# Bug Fixes
|
|
|
|
|
|
## astropy.modeling
|
|
|
|
|
|
* Fixed the Gaussian2D bounding_box when theta is an angular
|
|
|
|
|
|
Quantity. [#13021]
|
|
|
|
|
|
## astropy.utils
|
|
|
|
|
|
* Reverted astropy.utils.iers.iers.IERS_A_URL to
|
|
|
|
|
|
maia.usno.navy.mil domain instead of NASA FTP to work around
|
|
|
|
|
|
server issues. [#13004]
|
|
|
|
|
|
# Other Changes and Additions
|
|
|
|
|
|
* Updated bundled WCSLIB to version 7.9 with several bugfixes and
|
|
|
|
|
|
added support for time coordinate axes in wcsset() and
|
|
|
|
|
|
wcssub(). The four-digit type code for the time axis will have
|
|
|
|
|
|
the first digit set to 4, i.e., four digit code will be 4xxx
|
|
|
|
|
|
where x is a digit 0-9. For a full list of bug fixes see

# Bug Fixes
|
|
|
|
|
|
## astropy.convolution
|
|
|
|
|
|
* Bugfix in astropy.convolution.utils.discretize_model which
|
|
|
|
|
|
allows the function to handle a CompoundModel. Before this fix,
|
|
|
|
|
|
discretize_model was confusing CompoundModel with a callable
|
|
|
|
|
|
function. [#12959]
|
|
|
|
|
|
## astropy.io.fits
|
|
|
|
|
|
* Fix write and read FITS tables with multidimensional items,
|
|
|
|
|
|
using from_columns without previousely defined ColDefs
|
|
|
|
|
|
structure. [#12863]
|
|
|
|
|
|
## astropy.io.votable
|
|
|
|
|
|
* Fix VOTable linting to avoid use of shell option. [#12985]
|
|
|
|
|
|
astropy.utils
|
|
|
|
|
|
* Fix XML linting to avoid use of shell option. [#12985]
|
|
|
|
|
|
# Other Changes and Additions
|
|
|
|
|
|
* Updated the bundled CFITSIO library to 4.1.0. [#12967]
|
|
|
|
|
|
(when building --without system_cfitsio)
|
|
|
|
|
|
|
Accepting request 961615 from home:bnavigator:branches:devel:languages:python:numeric
- Update to 5.0.2
astropy.io.ascii
* Bugfix to add backwards compatibility for reading ECSV version
0.9 files with non-standard column datatypes (such as `object`,
`str`, `datetime64`, etc.), which would raise a ValueError in
ECSV version 1.0. [#12880]
* astropy.io.misc
* Bugfix for `units_mapping` schema's property name conflicts.
Changes:
- `inputs` to `unit_inputs`
- `outputs` to `unit_outputs` [#12800]
astropy.io.votable
* Fixed a bug where `astropy.io.votable.validate` was printing
output to `sys.stdout` when the `output` paramter was set to
`None`. `validate` now returns a string when `output` is set to
`None`, as documented. [#12604]
astropy.modeling
* Fix handling of units on `scale` parameter in BlackBody model.
[#12318]
* Indexing on models can now be used with all types of integers
(like `numpy.int64`) instead of just `int`. [#12561]
* Fix computation of the separability of a `CompoundModel` where
another `CompoundModel` is on the right hand side of the `&`
operator. [#12907]
* Provide a hook (`Model._calculate_separability_matrix`) to
allow subclasses of `Model` to define how to compute their
separability matrix. [#12900]
astropy.stats
* Fixed a bug in which running
`kuiper_false_positive_probability(D,N)` on distributions with
many data points could produce NaN values for the false
positive probability of the Kuiper statistic. [#12896]
astropy.wcs
* Fixed a bug due to which `naxis`, `pixel_shape`, and
`pixel_bounds` attributes of `astropy.wcs.WCS` were not
restored when an `astropy.wcs.WCS` object was unpickled. This
fix also eliminates `FITSFixedWarning` warning issued during
unpiclikng of the WCS objects related to the number of axes.
This fix also eliminates errors when unpickling WCS objects
originally created using non-default values for `key`,
`colsel`, and `keysel` parameters. [#12844]

Bug Fixes
|
|
|
|
|
|
astropy.io.fits
|
|
|
|
|
|
* In fits.io.getdata do not fall back to first non-primary
|
|
|
|
|
|
extension when user explicitly specifies an extension. [#11860]
|
|
|
|
|
|
* Ensure multidimensional masked columns round-trip properly to
|
|
|
|
|
|
FITS. [#11911]
|
|
|
|
|
|
* Ensure masked times round-trip to FITS, even if
|
|
|
|
|
|
multi-dimensional. [#11913]
|
|
|
|
|
|
* Raise ValueError if an np.float32 NaN/Inf value is assigned to
|
|
|
|
|
|
a header keyword. [#11922]
|
|
|
|
|
|
astropy.modeling
|
|
|
|
|
|
* Fixed bug in fix_inputs handling of bounding boxes. [#11908]
|
|
|
|
|
|
astropy.table
|
|
|
|
|
|
* Fix an error when converting to pandas any Table subclass that
|
|
|
|
|
|
automatically adds a table index when the table is created. An
|
|
|
|
|
|
example is a binned TimeSeries table. [#12018]
|
|
|
|
|
|
astropy.units
|
|
|
|
|
|
* Ensure that unpickling quantities and units in new sessions
|
|
|
|
|
|
does not change hashes and thus cause problems with (de)
|
|
|
|
|
|
composition such as getting different answers from the .si
|
|
|
|
|
|
attribute. [#11879]
|
|
|
|
|
|
* Fixed cannot import name imperial from astropy.units
|
|
|
|
|
|
namespace. [#11977]
|
|
|
|
|
|
astropy.utils
|
|
|
|
|
|
* Ensure any .info on Masked instances is propagated correctly
|
|
|
|
|
|
when viewing or slicing. As a consequence, MaskedQuantity can
|
|
|
|
|
|
now be correctly written to, e.g., ECSV format with
|
|
|
|
|
|
serialize_method='data_mask'. [#11910]

astropy.cosmology
|
|
|
|
|
|
* Fixed an issue where specializations of the comoving distance
|
|
|
|
|
|
calculation for certain cosmologies could not handle redshift
|
|
|
|
|
|
arrays. [#10980]
|
|
|
|
|
|
astropy.io.fits
|
|
|
|
|
|
* Fix bug where manual fixes to invalid header cards were not
|
|

|
|
|
preserved when saving a FITS file. [#11108]
|
|
|
|
|
|
astropy.io.votable
|
|
|

* NumericArray converter now properly broadcasts scalar mask to
|

|
|
|
array. [#11157]
|
|
|
|
|
|
astropy.table
|
|
|
|
|
|
* Fix bug when initializing a Table subclass that uses
|
|
|
|
|
|
TableAttribute's. If the data were an instance of the table
|
|
|
|
|
|
then attributes provided in the table initialization call
|
|
|
|
|
|
could be ignored. [#11217]
|
|
|
|
|
|
astropy.time
|
|
|
|
|
|
* Change epoch of TimeUnixTAI ("unix_tai") from
|
|
|
|
|
|
1970-01-01T00:00:00 UTC to 1970-01-01T00:00:00 TAI to match
|
|
|
|
|
|
the intended and documented behaviour. This essentially
|
|
|
|
|
|
changes the resulting times by 8.000082 seconds, the initial
|
|
|
|
|
|
offset between TAI and UTC. [#11249]
|
|
|
|
|
|
astropy.units
|
|
|
|
|
|
* Fixed a bug with the quantity_input decorator where allowing
|
|
|
|
|
|
dimensionless inputs for an argument inadvertently disabled
|
|
|
|
|
|
any checking of compatible units for that argument. [#11283]
|
|
|
|
|
|
astropy.utils
|
|
|
|
|
|
* Fix a bug so that np.shape, np.ndim and np.size again work on
|
|
|
|
|
|
classes that use ShapedLikeNDArray, like representations,
|
|
|
|
|
|
frames, sky coordinates, and times. [#11133]
|
|
|
|
|
|
astropy.wcs
|
|
|
|
|
|
* Fix error when a user defined proj_point parameter is passed
|
|
|
|
|
|
to fit_wcs_from_points. [#11139]

- Update to 4.0.3
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
Fixed a small bug where initializing an empty `Column`
|
|
|
|
|
|
with a structured dtype with a length and a shape
|
|
|
|
|
|
failed to give the requested dtype. [#10819]
|
|
|
|
|
|
* Fixed installation of the source distribution with
|
|
|
|
|
|
pip<19. [#10837, #10852]
|
|
|
|
|
|
|
Accepting request 840965 from home:bnavigator:branches:devel:languages:python:numeric
- Update to 4.0.2
New Features
* astropy.utils
astropy.utils.data.download_file now supports FTPS/FTP over
TLS. [#9964]
astropy.utils.data now uses a lock-free mechanism for caching.
This new mechanism uses a new cache layout and so ignores
caches created using earlier mechanisms (which were causing
lockups on clusters). The two cache formats can coexist but do
not share any files. [#10437, #10683]
astropy.utils.data now ignores the config item
astropy.utils.data.conf.download_cache_lock_attempts since no
locking is done. [#10437, #10683]
astropy.utils.data.download_file and related functions now
interpret the parameter or config file setting timeout=0 to
mean they should make no attempt to download files. [#10437,
#10683]
astropy.utils.import_file_to_cache now accepts a keyword-only
argument replace, defaulting to True, to determine whether it
should replace existing files in the cache, in a way as close
to atomic as possible. [#10437, #10683]
astropy.utils.data.download_file and related functions now
treat http://example.com and http://example.com/ as equivalent.
[#10631]
* astropy.wcs
The new auxiliary WCS parameters added in WCSLIB 7.1 are now
exposed as the aux attribute of Wcsprm. [#10333]
Updated bundled version of WCSLIB to v7.3. [#10433]
Bug fixes
* astropy.config
Added an extra fallback to os.expanduser('~') when trying to
find the user home directory. [#10570]
* astropy.constants
Corrected definition of parsec to 648 000 / pi AU following IAU
2015 B2 [#10569]
* astropy.convolution
Fixed a bug where a float-typed integers in the argument
x_range of astropy.convolution.utils.discretize_oversample_1D
(and the 2D version as well) fails because it uses
numpy.linspace, which requires an int. [#10696]
* astropy.coordinates
Ensure that for size-1 array SkyCoord and coordinate frames the
attributes also properly become scalars when indexed with 0.
[#10113]
Fixed a bug where SkyCoord.separation() and
SkyCoord.separation_3d were not accepting a frame object.
[#10332]
Ensure that the lon values in SkyOffsetFrame are wrapped
correctly at 180 degree regardless of how the underlying data
is represented. [#10163]
Fixed an error in the obliquity of the ecliptic when
transforming to/from the *TrueEcliptic coordinate frames. The
error would primarily result in an inaccuracy in the ecliptic
latitude on the order of arcseconds. [#10129]
Fixed an error in the computation of the location of solar
system bodies where the Earth location of the observer was
ignored during the correction for light travel time. [#10292]
Ensure that coordinates with proper motion that are transformed
to other coordinate frames still can be represented properly.
[#10276]
Improve the error message given when trying to get a cartesian
representation for coordinates that have both proper motion and
radial velocity, but no distance. [#10276]
Fixed an error where SkyCoord.apply_space_motion would return
incorrect results when no distance is set and proper motion is
high. [#10296]
Make the parsing of angles thread-safe so that Angle can be
used in Python multithreading. [#10556]
Fixed reporting of EarthLocation.info which previously raised
an exception. [#10592]
* astropy.io.ascii
Fixed a bug with the C fast_reader not correctly parsing
newlines when delimiter was also set to \n or \r; ensured
consistent handling of input strings without newline
characters. [#9929]
* astropy.io.fits
Fix integer formats of TFORMn=Iw columns in ASCII tables to
correctly read values exceeding int32 - setting int16, int32 or
int64 according to w. [#9901]
Fix unclosed memory-mapped FITS files in FITSDiff when
difference found. [#10159]
Fix crash when reading an invalid table file. [#10171]
Fix duplication issue when setting a keyword ending with space.
[#10482]
Fix ResourceWarning with fits.writeto and pathlib.Path object.
[#10599]
Fix repr for commentary cards and strip spaces for commentary
keywords. [#10640]
Fix compilation of cfitsio with Xcode 12. [#10772]
Fix handling of 1-dimensional arrays with a single element in
BinTableHDU [#10768]
* astropy.io.misc

- Update to 4.0.2
|
|
|
|
|
|
New Features
|
|
|
|
|
|
* astropy.utils
|
|
|
|
|
|
astropy.utils.data.download_file now supports FTPS/FTP over
|
|
|
|
|
|
TLS. [#9964]
|
|
|
|
|
|
astropy.utils.data now uses a lock-free mechanism for caching.
|
|
|
|
|
|
This new mechanism uses a new cache layout and so ignores
|
|
|
|
|
|
caches created using earlier mechanisms (which were causing
|
|
|
|
|
|
lockups on clusters). The two cache formats can coexist but do
|
|
|
|
|
|
not share any files. [#10437, #10683]
|
|
|
|
|
|
astropy.utils.data now ignores the config item
|
|
|
|
|
|
astropy.utils.data.conf.download_cache_lock_attempts since no
|
|
|
|
|
|
locking is done. [#10437, #10683]
|
|
|
|
|
|
astropy.utils.data.download_file and related functions now
|
|
|
|
|
|
interpret the parameter or config file setting timeout=0 to
|
|
|
|
|
|
mean they should make no attempt to download files. [#10437,
|
|
|
|
|
|
#10683]
|
|
|
|
|
|
astropy.utils.import_file_to_cache now accepts a keyword-only
|
|
|
|
|
|
argument replace, defaulting to True, to determine whether it
|
|
|
|
|
|
should replace existing files in the cache, in a way as close
|
|
|
|
|
|
to atomic as possible. [#10437, #10683]
|
|
|
|
|
|
astropy.utils.data.download_file and related functions now
|
|
|
|
|
|
treat http://example.com and http://example.com/ as equivalent.
|
|
|
|
|
|
[#10631]
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
The new auxiliary WCS parameters added in WCSLIB 7.1 are now
|
|
|
|
|
|
exposed as the aux attribute of Wcsprm. [#10333]
|
|
|
|
|
|
Updated bundled version of WCSLIB to v7.3. [#10433]
|
|
|
|
|
|
Bug fixes
|
|
|
|
|
|
* astropy.config
|
|
|
|
|
|
Added an extra fallback to os.expanduser('~') when trying to
|
|
|
|
|
|
find the user home directory. [#10570]
|
|
|
|
|
|
* astropy.constants
|
|
|
|
|
|
Corrected definition of parsec to 648 000 / pi AU following IAU
|
|
|
|
|
|
2015 B2 [#10569]
|
|
|
|
|
|
* astropy.convolution
|
|
|
|
|
|
Fixed a bug where a float-typed integers in the argument
|
|
|
|
|
|
x_range of astropy.convolution.utils.discretize_oversample_1D
|
|
|
|
|
|
(and the 2D version as well) fails because it uses
|
|
|
|
|
|
numpy.linspace, which requires an int. [#10696]
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
Ensure that for size-1 array SkyCoord and coordinate frames the
|
|
|
|
|
|
attributes also properly become scalars when indexed with 0.
|
|
|
|
|
|
[#10113]
|
|
|
|
|
|
Fixed a bug where SkyCoord.separation() and
|
|
|
|
|
|
SkyCoord.separation_3d were not accepting a frame object.
|
|
|
|
|
|
[#10332]
|
|
|
|
|
|
Ensure that the lon values in SkyOffsetFrame are wrapped
|
|
|
|
|
|
correctly at 180 degree regardless of how the underlying data
|
|
|
|
|
|
is represented. [#10163]
|
|
|
|
|
|
Fixed an error in the obliquity of the ecliptic when
|
|
|
|
|
|
transforming to/from the *TrueEcliptic coordinate frames. The
|
|
|
|
|
|
error would primarily result in an inaccuracy in the ecliptic
|
|
|
|
|
|
latitude on the order of arcseconds. [#10129]
|
|
|
|
|
|
Fixed an error in the computation of the location of solar
|
|
|
|
|
|
system bodies where the Earth location of the observer was
|
|
|
|
|
|
ignored during the correction for light travel time. [#10292]
|
|
|
|
|
|
Ensure that coordinates with proper motion that are transformed
|
|
|
|
|
|
to other coordinate frames still can be represented properly.
|
|
|
|
|
|
[#10276]
|
|
|
|
|
|
Improve the error message given when trying to get a cartesian
|
|
|
|
|
|
representation for coordinates that have both proper motion and
|
|
|
|
|
|
radial velocity, but no distance. [#10276]
|
|
|
|
|
|
Fixed an error where SkyCoord.apply_space_motion would return
|
|
|
|
|
|
incorrect results when no distance is set and proper motion is
|
|
|
|
|
|
high. [#10296]
|
|
|
|
|
|
Make the parsing of angles thread-safe so that Angle can be
|
|
|
|
|
|
used in Python multithreading. [#10556]
|
|
|
|
|
|
Fixed reporting of EarthLocation.info which previously raised
|
|
|
|
|
|
an exception. [#10592]
|
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
|
Fixed a bug with the C fast_reader not correctly parsing
|
|
|
|
|
|
newlines when delimiter was also set to \n or \r; ensured
|
|
|
|
|
|
consistent handling of input strings without newline
|
|
|
|
|
|
characters. [#9929]
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
Fix integer formats of TFORMn=Iw columns in ASCII tables to
|
|
|
|
|
|
correctly read values exceeding int32 - setting int16, int32 or
|
|
|
|
|
|
int64 according to w. [#9901]
|
|
|
|
|
|
Fix unclosed memory-mapped FITS files in FITSDiff when
|
|
|
|
|
|
difference found. [#10159]
|
|
|
|
|
|
Fix crash when reading an invalid table file. [#10171]
|
|
|
|
|
|
Fix duplication issue when setting a keyword ending with space.
|
|
|
|
|
|

|
|
|
|
|
|
Fix ResourceWarning with fits.writeto and pathlib.Path object.
|
|
|
|
|
|
[#10599]
|
|
|
|

|
|
|
|
|
|
keywords. [#10640]

a change in behavior in asdf 2.8. [#10674]
|
|
|
|
|
|
* astropy.io.registry

|
|
|
|
|
|
* astropy.io.votable
|
|
|
|
|
|
Fixed parsing failure of VOTable with no fields. When detecting
|
|
|
|
|
|
a non-empty table with no fields, the following warning/
|
|
|
|
|
|
exception is issued: E25 "No FIELDs are defined; DATA section

Fixed an issue where sigma_clip and SigmaClip.__call__ would
|
|
|
|
|
|
return a masked array instead of a ndarray when masked=False

|
|
|
|
and the input was a full-masked MaskedArray. [#10099]
|
|
|
|
|
|
Fixed bug with funcs.poisson_conf_interval where an integer for

ECSV or HDF5. If one of the data attributes of the mixin (e.g.
|
|
|
|
|
|
skycoord.ra) had the same name as one of the table column names
|
|
|
|

contain np.ma.masked elements to indicate masked data. [#10636]
|
|
|
|
|

|
|
|
- Update to 4.0
|
|
|
|
|
|
+ New Features
|
|
|
|
|
|
> astropy.config
|
|
|
|
|
|
* The config and cache directories and the name of the config file are now
|
|
|
|
|
|
customizable. This allows affiliated packages to put their configuration
|
|
|
|
|
|
files in locations other than ``CONFIG_DIR/.astropy/``.
|
|
|
|
|
|
> astropy.constants
|
|
|
|
|
|
* The version of constants can be specified via ScienceState in a way
|
|
|
|
|
|
that ``constants`` and ``units`` will be consistent.
|
|
|
|
|
|
* Default constants now use CODATA 2018 and IAU 2015 definitions.
|
|
|
|
|
|
* Constants can be pickled and unpickled.
|
|
|
|
|
|
> astropy.convolution
|
|
|
|
|
|
* Fixed a bug where having a kernel defined using unitless astropy
|
|
|
|
|
|
quantity objects would result in a crash
|
|
|
|
|
|
> astropy.coordinates
|
|
|
|
|
|
* Changed ``coordinates.solar_system_ephemeris`` to also accept local files
|
|
|
|
|
|
as input. The ephemeris can now be selected by either keyword (e.g. 'jpl',
|
|
|
|
|
|
'de430'), URL or file path.
|
|
|
|
|
|
* Added a ``cylindrical`` property to ``SkyCoord`` for shorthand access to a
|
|
|
|
|
|
``CylindricalRepresentation`` of the coordinate, as is already available
|
|
|
|
|
|
for other common representations.
|
|
|
|
|
|
* The default parameters for the ``Galactocentric`` frame are now controlled by
|
|
|
|
|
|
a ``ScienceState`` subclass, ``galactocentric_frame_defaults``. New
|
|
|
|
|
|
parameter sets will be added to this object periodically to keep up with
|
|
|
|
|
|
ever-improved measurements of the solar position and motion.
|
|
|
|
|
|
* Coordinate frame classes can now have multiple aliases by assigning a list
|
|
|
|
|
|
of aliases to the class variable ``name``. Any of the aliases can be used
|
|
|
|
|
|
for attribute-style access or as the target of ``tranform_to()`` calls.
|
|
|
|
|
|
|
|
|
|
|
|
* Passing a NaN to ``Distance`` no longer raises a warning.
|
|
|
|
|
|
> astropy.cosmology
|
|
|
|
|
|
* The pre-publication Planck 2018 cosmological parameters are included as the
|
|
|
|
|
|
``Planck2018_arXiv_v2`` object. Please note that the values are preliminary,
|
|
|
|
|
|
and when the paper is accepted a final version will be included as
|
|
|
|
|
|
``Planck18``.
|
|
|
|
|
|
> astropy.io.ascii
|
|
|
|
|
|
* Removed incorrect warnings on ``Overflow`` when reading in
|
|
|
|
|
|
``FloatType`` 0.0 with ``use_fast_converter``; synchronised
|
|
|
|
|
|
``IntType`` ``Overflow`` warning messages.
|
|
|
|
|
|
> astropy.io.misc
|
|
|
|
|
|
* Eliminate deprecated compatibility mode when writing ``Table`` metadata to
|
|
|
|
|
|
HDF5 format.
|
|
|
|
|
|
* Add support for orthogonal polynomial models to ASDF.
|
|
|
|
|
|
> astropy.io.fits
|
|
|
|
|
|
* Changed the ``fitscheck`` and ``fitsdiff`` script to use the ``argparse``
|
|
|
|
|
|
module instead of ``optparse``.
|
|
|
|
|
|
* Allow writing of ``Table`` objects with ``Time`` columns that are also table
|
|
|
|
|
|
indices to FITS files.
|
|
|
|
|
|
> astropy.io.votable
|
|
|
|
|
|
* Support VOTable version 1.4. The main addition is the new element, TIMESYS,
|
|
|
|
|
|
which allows defining of metadata for temporal coordinates much like COOSYS
|
|
|
|
|
|
defines metadata for celestial coordinates.
|
|
|
|
|
|
> astropy.logger
|
|
|
|
|
|
* Added a configuration option to specify the text encoding of the log file,
|
|
|
|
|
|
with the default behavior being the platform-preferred encoding.
|
|
|
|
|
|
> astropy.modeling
|
|
|
|
|
|
* Major rework of modeling internals. `See modeling documentation for details.
|
|
|
|
|
|
<https://docs.astropy.org/en/v4.0.x/modeling/changes_for_4.html>`_ .
|
|
|
|
|
|
* Add ``Tabular1D.inverse``.
|
|
|
|
|
|
* ``Model.rename`` was changed to add the ability to rename ``Model.inputs``
|
|
|
|
|
|
and ``Model.outputs``.
|
|
|
|
|
|
* New function ``fix_inputs`` to generate new models from others by fixing
|
|
|
|
|
|
specific inputs variable values to constants.
|
|
|
|
|
|
* ``inputs`` and ``outputs`` are now model instance attributes, and ``n_inputs``
|
|
|
|
|
|
and ``n_outputs`` are class attributes. Backwards compatible default
|
|
|
|
|
|
values of ``inputs`` and ``outputs`` are generated. ``Model.inputs`` and
|
|
|
|
|
|
``Model.outputs`` are now settable which allows renaming them on per user
|
|
|
|
|
|
case.
|
|
|
|
|
|
* Add a new model representing a sequence of rotations in 3D around an
|
|
|
|
|
|
arbitrary number of axes.
|
|
|
|
|
|
* Add many of the numpy ufunc functions as models.
|
|
|
|
|
|
* Add ``BlackBody`` model.
|
|
|
|
|
|
* Add ``Drude1D`` model.
|
|
|
|
|
|
* Added analytical King model (KingProjectedAnalytic1D).
|
|
|
|
|
|
* Added Exponential1D and Logarithmic1D models.
|
|
|
|
|
|
> astropy.nddata
|
|
|
|
|
|
* Add a way for technically invalid but unambiguous units in a fits header
|
|
|
|
|
|
to be parsed by ``CCDData``.
|
|
|
|
|
|
* ``NDData`` now only accepts WCS objects which implement either the high, or
|
|
|
|
|
|
low level APE 14 WCS API. All WCS objects are converted to a high level WCS
|
|
|
|
|
|
object, so ``NDData.wcs`` now always returns a high level APE 14 object. Not
|
|
|
|
|
|
all array slices are valid for wcs objects, so some slicing operations which
|
|
|
|
|
|
used to work may now fail.
|
|
|
|
|
|
> astropy.stats
|
|
|
|
|
|
* The ``biweight_location``, ``biweight_scale``, and
|
|
|
|
|
|
``biweight_midvariance`` functions now allow for the ``axis``
|
|
|
|
|
|
keyword to be a tuple of integers.
|
|
|
|
|
|
* Added an ``ignore_nan`` option to the ``biweight_location``,
|
|
|
|
|
|
``biweight_scale``, and ``biweight_midvariance`` functions.
|
|
|
|
|
|
* A numpy ``MaskedArray`` can now be input to the ``biweight_location``,
|
|
|
|
|
|
``biweight_scale``, and ``biweight_midvariance`` functions.
|
|
|
|
|
|
* Removed the warning related to p0 in the Bayesian blocks algorithm. The
|
|
|
|
|
|
caveat related to p0 is described in the docstring for ``Events``.
|
|
|
|
|
|
> astropy.table
|
|
|
|
|
|
* Improved the implementation of ``Table.replace_column()`` to provide
|
|
|
|
|
|
a speed-up of 5 to 10 times for wide tables. The method can now accept
|
|
|
|
|
|
any input which convertible to a column of the correct length, not just
|
|
|
|
|
|
``Column`` subclasses.
|
|
|
|
|
|
* Improved the implementation of ``Table.add_column()`` to provide a speed-up
|
|
|
|
|
|
of 2 to 10 (or more) when adding a column to tables, with increasing benefit
|
|
|
|
|
|
as the number of columns increases. The method can now accept any input
|
|
|
|
|
|
which is convertible to a column of the correct length, not just ``Column``
|
|
|
|
|
|
subclasses.
|
|
|
|
|
|
* Changed the implementation of ``Table.add_columns()`` to use the new
|
|
|
|
|
|
``Table.add_column()`` method. In most cases the performance is similar
|
|
|
|
|
|
or slightly faster to the previous implemenation.
|
|
|
|
|
|
* ``MaskedColumn.data`` will now return a plain ``MaskedArray`` rather than
|
|
|
|
|
|
the previous (unintended) ``masked_BaseColumn``.
|
|
|
|
|
|
* Added depth-wise stacking ``dstack()`` in higher level table operation.
|
|
|
|
|
|
It help will in stacking table column depth-wise.
|
|
|
|
|
|
* Added a new table equality method ``values_equal()`` which allows comparison
|
|
|
|
|
|
table values to another table, list, or value, and returns an
|
|
|
|
|
|
element-by-element equality table.
|
|
|
|
|
|
* Added new ``join_type='cartesian'`` option to the ``join`` operation.
|
|
|
|
|
|
* Allow adding a table column as a list of mixin-type objects, for instance
|
|
|
|
|
|
``t['q'] = [1 * u.m, 2 * u.m]``.
|
|
|
|
|
|
* Allow table ``join()`` using any sortable key column (e.g. Time), not
|
|
|
|
|
|
just ndarray subclasses. A column is considered sortable if there is a
|
|
|
|
|
|
``<column>.info.get_sortable_arrays()`` method that is implemented.
|
|
|
|
|
|
* Added ``Table.iterrows()`` for making row-wise iteration faster.
|
|
|
|
|
|
* Allow table to be initialized with a list of dict where the dict keys
|
|
|
|
|
|
are not the same in every row. The table column names are the set of all keys
|
|
|
|
|
|
found in the input data, and any missing key/value pairs are turned into
|
|
|
|
|
|
missing data in the table.
|
|
|
|
|
|
* Prevent unnecessary ERFA warnings when indexing by ``Time`` columns.
|
|
|
|
|
|
* Added support for sorting tables which contain non-mutable mixin columns
|
|
|
|
|
|
(like ``SkyCoord``) for which in-place item update is not allowed.
|
|
|
|
|
|
* Ensured that inserting ``np.ma.masked`` (or any other value with a mask) into
|
|
|
|
|
|
a ``MaskedColumn`` causes a masked entry to be inserted.
|
|
|
|
|
|
* Fixed a bug that caused an exception when initializing a ``MaskedColumn`` from
|
|
|
|
|
|
another ``MaskedColumn`` that has a structured dtype.
|
|
|
|
|
|
> astropy.tests
|
|
|
|
|
|
* The plugin that handles the custom header in the test output has been
|
|
|
|
|
|
moved to the ``pytest-astropy-header plugin`` package. `See the README at
|
|
|
|
|
|
<https://github.com/astropy/pytest-astropy-header>`__ for information about
|
|
|
|
|
|
using this new plugin.
|
|
|
|
|
|
> astropy.time
|
|
|
|
|
|
* Added a new time format ``ymdhms`` for representing times via year, month,
|
|
|
|
|
|
day, hour, minute, and second attributes.
|
|
|
|
|
|
* ``TimeDelta`` gained a ``to_value`` method, so that it becomes easier to
|
|
|
|
|
|
use it wherever a ``Quantity`` with units of time could be used.
|
|
|
|
|
|
* Made scalar ``Time`` and ``TimeDelta`` objects hashable based on JD, time
|
|
|
|
|
|
scale, and location attributes.
|
|
|
|
|
|
* Improved error message when bad input is used to initialize a ``Time`` or
|
|
|
|
|
|
``TimeDelta`` object and the format is specified.
|
|
|
|
|
|
* Allow numeric time formats to be initialized with numpy ``longdouble``,
|
|
|
|
|
|
``Decimal`` instances, and strings. One can select just one of these
|
|
|
|
|
|
using ``in_subfmt``. The output can be similarly set using ``out_subfmt``.
|
|
|
|
|
|
|
|
|
|
|
|
* Introduce a new ``.to_value()`` method for ``Time`` (and adjusted the
|
|
|
|
|
|
existing method for ``TimeDelta``) so that one can get values in a given
|
|
|
|
|
|
``format`` and possible ``subfmt`` (e.g., ``to_value('mjd', 'str')``.
|
|
|
|
|
|
* Prevent unecessary ERFA warnings when sorting ``Time`` objects.
|
|
|
|
|
|
> astropy.timeseries
|
|
|
|
|
|
* Addig ``epoch_phase``, ``wrap_phase`` and ``normalize_phase`` keywords to
|
|
|
|
|
|
``TimeSeries.fold()`` to control the phase of the epoch and to return
|
|
|
|
|
|
normalized phase rather than time for the folded TimeSeries.
|
|
|
|
|
|
> astropy.uncertainty
|
|
|
|
|
|
* ``Distribution`` was rewritten such that it deals better with subclasses.
|
|
|
|
|
|
As a result, Quantity distributions now behave correctly with ``to`` methods
|
|
|
|
|
|
yielding new distributions of the kind expected for the starting
|
|
|
|
|
|
distribution, and ``to_value`` yielding ``NdarrayDistribution`` instances.
|
|
|
|
|
|
|
|
|
|
|
|
* The ``pdf_*`` properties that were used to calculate statistical properties
|
|
|
|
|
|
of ``Distrubution`` instances were changed into methods. This allows one
|
|
|
|
|
|
to pass parameters such as ``ddof`` to ``pdf_std`` and ``pdf_var`` (which
|
|
|
|
|
|
generally should equal 1 instead of the default 0), and reflects that these
|
|
|
|
|
|
are fairly involved calcuations, not just "properties".
|
|
|
|
|
|
> astropy.units
|
|
|
|
|
|
* Support for unicode parsing. Currently supported superscripts are Ohm,
|
|
|
|
|
|
Ångström, and the micro-sign.
|
|
|
|
|
|
* Accept non-unit type annotations in @quantity_input.
|
|
|
|
|
|
* For numpy 1.17 and later, the new ``__array_function__`` protocol is used to
|
|
|
|
|
|
ensure that all top-level numpy functions interact properly with
|
|
|
|
|
|
``Quantity``, preserving units also in operations like ``np.concatenate``.
|
|
|
|
|
|
|
|
|
|
|
|
* Add equivalencies for surface brightness units to spectral_density.
|
|
|
|
|
|
> astropy.utils
|
|
|
|
|
|
* ``astropy.utils.data.download_file`` and
|
|
|
|
|
|
``astropy.utils.data.get_readable_fileobj`` now provides an ``http_headers``
|
|
|
|
|
|
keyword to pass in specific request headers for the download. It also now
|
|
|
|
|
|
defaults to providing ``User-Agent: Astropy`` and ``Accept: */*``
|
|
|
|
|
|
headers. The default ``User-Agent`` value can be set with a new
|
|
|
|
|
|
``astropy.data.conf.default_http_user_agent`` configuration item.
|
|
|
|
|
|
|
|
|
|
|
|
* Added a new ``astropy.utils.misc.unbroadcast`` function which can be used
|
|
|
|
|
|
to return the smallest array that can be broadcasted back to the initial
|
|
|
|
|
|
array.
|
|
|
|
|
|
* The specific IERS Earth rotation parameter table used for time and
|
|
|
|
|
|
coordinate transformations can now be set, either in a context or per
|
|
|
|
|
|
session, using ``astropy.utils.iers.earth_rotation_table``.
|
|
|
|
|
|
* Added ``export_cache`` and ``import_cache`` to permit transporting
|
|
|
|
|
|
downloaded data to machines with no Internet connection. Several new
|
|
|
|
|
|
functions are available to investigate the cache contents; e.g.,
|
|
|
|
|
|
``check_download_cache`` can be used to confirm that the persistent
|
|
|
|
|
|
cache has not become damaged.
|
|
|
|
|
|
* A new ``astropy.utils.iers.LeapSeconds`` class has been added to track
|
|
|
|
|
|
leap seconds.
|
|
|
|
|
|
> astropy.visualization
|
|
|
|
|
|
* Added a new ``time_support`` context manager/function for making it easy to
|
|
|
|
|
|
plot and format ``Time`` objects in Matplotlib.
|
|
|
|
|
|
* Added support for plotting any WCS compliant with the generalized (APE 14)
|
|
|
|
|
|
WCS API with WCSAxes.
|
|
|
|
|
|
* Improved display of information when inspecting ``WCSAxes.coords``.
|
|
|
|
|
|
* Improved error checking for the ``slices=`` argument to ``WCSAxes``.
|
|
|
|
|
|
* Added support for more solar frames in WCSAxes.
|
|
|
|
|
|
* Add support for one dimensional plots to ``WCSAxes``.
|
|
|
|
|
|
* Add a ``get_format_unit`` to ``wcsaxes.CoordinateHelper``.
|
|
|
|
|
|
* ``WCSAxes`` now, by default, sets a default label for plot axes which is the
|
|
|
|
|
|
WCS physical type (and unit) for that axis. This can be disabled using the
|
|
|
|
|
|
``coords[i].set_auto_axislabel(False)`` or by explicitly setting an axis
|
|
|
|
|
|
label.
|
|
|
|
|
|
* Fixed the display of tick labels when plotting all sky images that have a
|
|
|
|
|
|
coord_wrap less than 360.
|
|
|
|
|
|
> astropy.wcs
|
|
|
|
|
|
* Added a ``astropy.wcs.wcsapi.pixel_to_pixel`` function that can be used to
|
|
|
|
|
|
transform pixel coordinates in one dataset with a WCS to pixel coordinates
|
|
|
|
|
|
in another dataset with a different WCS. This function is designed to be
|
|
|
|
|
|
efficient when the input arrays are broadcasted views of smaller
|
|
|
|
|
|
arrays.
|
|
|
|
|
|
* Added a ``local_partial_pixel_derivatives`` function that can be used to
|
|
|
|
|
|
determine a matrix of partial derivatives of each world coordinate with
|
|
|
|
|
|
respect to each pixel coordinate.
|
|
|
|
|
|
* Updated wcslib to v6.4.
|
|
|
|
|
|
* Improved the ``SlicedLowLevelWCS`` class in ``astropy.wcs.wcsapi`` to avoid
|
|
|
|
|
|
storing chains of nested ``SlicedLowLevelWCS`` objects when applying multiple
|
|
|
|
|
|
slicing operations in turn.
|
|
|
|
|
|
* Added a ``wcs_info_str`` function to ``astropy.wcs.wcsapi`` to show a summary
|
|
|
|
|
|
of an APE-14-compliant WCS as a string.
|
|
|
|
|
|
* Added two new optional attributes to the APE 14 low-level WCS:
|
|
|
|
|
|
``pixel_axis_names`` and ``world_axis_names``.
|
|
|
|
|
|
* Updated the WCS class to now correctly take and return ``Time`` objects in
|
|
|
|
|
|
the high-level APE 14 API (e.g. ``pixel_to_world``.
|
|
|
|
|
|
* ``SlicedLowLevelWCS`` now raises ``IndexError`` rather than ``ValueError`` on
|
|
|
|
|
|
an invalid slice.
|
|
|
|
|
|
* Added ``fit_wcs_from_points`` function to ``astropy.wcs.utils``. Fits a WCS
|
|
|
|
|
|
object to set of matched detector/sky coordinates.
|
|
|
|
|
|
* Fix various bugs in ``SlicedLowLevelWCS`` when the WCS being sliced was one
|
|
|
|
|
|
dimensional.

|
|
* Removed the deprecated keyword argument ``stddev`` from

|
|
|
* Deprecated and renamed ``MexicanHat1DKernel`` and ``MexicanHat2DKernel``

> astropy.coordinates
|
|
|
|
|
|
* Removed the ``recommended_units`` attribute from Representations; it was
|
|
|
|
|
|
deprecated since 3.0.
|
|
|
|
|
|
* Removed the deprecated frame attribute classes, ``FrameAttribute``,
|
|
|
|
|
|
``TimeFrameAttribute``, ``QuantityFrameAttribute``,
|
|
|
|
|
|
``CartesianRepresentationFrameAttribute``; deprecated since 3.0.
|
|
|
|
|
|
* Removed ``longitude`` and ``latitude`` attributes from ``EarthLocation``;
|
|
|
|
|
|
deprecated since 2.0.
|
|
|
|
|
|
* The ``DifferentialAttribute`` for frame classes now passes through any input
|
|
|
|
|
|
to the ``allowed_classes`` if only one allowed class is specified, i.e. this
|
|
|
|
|
|
now allows passing a quantity in for frame attributes that use
|
|
|
|
|
|
``DifferentialAttribute``.
|
|
|
|
|
|
* Removed the deprecated ``galcen_ra`` and ``galcen_dec`` attributes from the

|
|
|
|
``Galactocentric`` frame.
|
|
|

|
|
|
|
|

|
|
|

|
|
* Masked column handling has changed, see ``astropy.table`` entry below.
|
|
|
|
|
|
|
|
|
|
|
|
* Removed deprecated ``usecPickle`` kwarg from ``fnunpickle`` and
|
|
|
|
|
|
``fnpickle``.
|
|
|
|
|
|
> astropy.io.fits
|
|
|
|
|
|
* Masked column handling has changed, see ``astropy.table`` entry below.
|
|
|
|
|
|
|
|
|
|
|
|
* ``io.fits.Header`` has been made safe for subclasses for copying and slicing.
|
|
|
|
|
|
As a result of this change, the private subclass ``CompImageHeader``
|
|
|
|
|
|
now always should be passed an explicit ``image_header``.
|
|
|
|
|
|
* Removed the deprecated ``tolerance`` option in ``fitsdiff`` and
|
|
|
|
|
|
``io.fits.diff`` classes.
|
|
|
|
|
|
* Removed deprecated keyword arguments for ``CompImageHDU``:
|
|
|
|
|
|
``compressionType``, ``tileSize``, ``hcompScale``, ``hcompSmooth``,
|
|
|
|
|
|
``quantizeLevel``.
|
|
|
|
|
|
> astropy.io.votable
|
|
|
|
|
|
* Changed ``pedantic`` argument to ``verify`` and change it to have three
|
|
|
|
|
|
string-based options (``ignore``, ``warn``, and ``exception``) instead of
|
|
|
|
|
|
just being a boolean. In addition, changed default to ``ignore``, which means
|
|
|
|
|
|
that warnings will not be shown by default when loading VO tables.
|
|
|
|
|
|
> astropy.modeling
|
|
|
|
|
|
* Eliminates support for compound classes (but not compound instances!)
|
|
|
|
|
|
* Slicing compound models more restrictive.
|
|
|
|
|
|
* Shape of parameters now includes n_models as dimension.
|
|
|
|
|
|
* Parameter instances now hold values instead of models.
|
|
|
|
|
|
* Compound model parameters now share instance and value with
|
|
|
|
|
|
constituent models.
|
|
|
|
|
|
* No longer possible to assign slices of parameter values to model parameters
|
|
|
|
|
|
attribute (it is possible to replace it with a complete array).
|
|
|
|
|
|
* Many private attributes and methods have changed (see documentation).
|
|
|
|
|
|
* Deprecated ``BlackBody1D`` model and ``blackbody_nu`` and
|
|
|
|
|
|
``blackbody_lambda`` functions.
|
|
|
|
|
|
* The deprecated ``rotations.rotation_matrix_from_angle`` was removed.
|
|
|
|
|
|
* Deprecated and renamed ``MexicanHat1D`` and ``MexicanHat2D``
|
|
|
|
|
|
to ``RickerWavelet1D`` and ``RickerWavelet2D``.
|
|
|
|
|
|
* Deprecated ``modeling.utils.ExpressionTree``.
|
|
|
|
|
|
> astropy.stats
|
|
|
|
|
|
* Removed the ``iters`` keyword from sigma clipping stats functions.
|
|
|
|
|
|
* Renamed the ``a`` parameter to ``data`` in biweight stat functions.
|
|
|
|
|
|
* Renamed the ``a`` parameter to ``data`` in ``median_absolute_deviation``.
|
|
|
|
|
|
|
|
|
|
|
|
* Renamed the ``conflevel`` keyword to ``confidence_level`` in
|
|
|
|
|
|
``poisson_conf_interval``. Usage of ``conflevel`` now issues
|
|
|
|
|
|
``AstropyDeprecationWarning``.
|
|
|
|
|
|
* Renamed the ``conf`` keyword to ``confidence_level`` in
|
|
|
|
|
|
``binom_conf_interval`` and ``binned_binom_proportion``. Usage of ``conf``
|
|
|
|
|
|
now issues ``AstropyDeprecationWarning``.
|
|
|
|
|
|
* Renamed the ``conf_lvl`` keyword to ``confidence_level`` in
|
|
|
|
|
|
``jackknife_stats``. Usage of ``conf_lvl`` now issues
|
|
|
|
|
|
``AstropyDeprecationWarning``.
|
|
|
|
|
|
> astropy.table
|
|
|
|
|
|
* The handling of masked columns in the ``Table`` class has changed in a way
|
|
|
|
|
|
that may impact program behavior. Now a ``Table`` with ``masked=False``
|
|
|
|
|
|
may contain both ``Column`` and ``MaskedColumn`` objects, and adding a
|
|
|
|
|
|
masked column or row to a table no longer "upgrades" the table and columns
|
|
|
|
|
|
to masked. This means that tables with masked data which are read via
|
|
|
|
|
|
``Table.read()`` will now always have ``masked=False``, though specific
|
|
|
|
|
|
columns will be masked as needed. Two new table properties
|
|
|
|
|
|
``has_masked_columns`` and ``has_masked_values`` were added. See the
|
|
|
|
|
|
`Masking change in astropy 4.0 section within
|
|
|
|
|
|
<https://docs.astropy.org/en/v4.0.x/table/masking.html>`_ for
|
|
|
|
|
|
details.
|
|
|
|
|
|
* Table operation functions such as ``join``, ``vstack``, ``hstack``, etc now
|
|
|
|
|
|
always return a table with ``masked=False``, though the individual columns
|
|
|
|
|
|
may be masked as necessary.
|
|
|
|
|
|
* Changed implementation of ``Table.add_column()`` and ``Table.add_columns()``
|
|
|
|
|
|
methods. Now it is possible add any object(s) which can be converted or
|
|
|
|
|
|
broadcasted to a valid column for the table. ``Table.__setitem__`` now
|
|
|
|
|
|
just calls ``add_column``.
|
|
|
|
|
|
* Changed default table configuration setting ``replace_warnings`` from
|
|
|
|
|
|
``['slice']`` to ``[]``. This removes the default warning when replacing
|
|
|
|
|
|
a table column that is a slice of another column.
|
|
|
|
|
|
* Removed the non-public method
|
|
|
|
|
|
``astropy.table.np_utils.recarray_fromrecords``.
|
|
|
|
|
|
> astropy.tests
|
|
|
|
|
|
* In addition to ``DeprecationWarning``, now ``FutureWarning`` and
|
|
|
|
|
|
``ImportWarning`` would also be turned into exceptions.
|
|
|
|
|
|
* ``warnings_to_ignore_by_pyver`` option in
|
|
|
|
|
|
``enable_deprecations_as_exceptions()`` has changed. Please refer to API
|
|
|
|
|
|
documentation.
|
|
|
|
|
|
* Default settings for ``warnings_to_ignore_by_pyver`` are updated to remove
|
|
|
|
|
|
very old warnings that are no longer relevant and to add a new warning
|
|
|
|
|
|
caused by ``pytest-doctestplus``.
|
|
|
|
|
|
> astropy.time
|
|
|
|
|
|
* ``Time.get_ut1_utc`` now uses the auto-updated ``IERS_Auto`` by default,
|
|
|
|
|
|
instead of the bundled ``IERS_B`` file.
|
|
|
|
|
|
* Time formats that do not use ``val2`` now raise ValueError instead of
|
|
|
|
|
|
silently ignoring a provided value.
|
|
|
|
|
|
* Custom time formats can now accept floating-point types with extended
|
|
|
|
|
|
precision. Existing time formats raise exceptions rather than discarding
|
|
|
|
|
|
extended precision through conversion to ordinary floating-point.
|
|
|
|
|
|
* Time formats (implemented in subclasses of ``TimeFormat``) now have
|
|
|
|
|
|
their input and output routines more thoroughly validated, making it more
|
|
|
|
|
|
difficult to create damaged ``Time`` objects.
|
|
|
|
|
|
* The ``TimeDelta.to_value()`` method now can also take the ``format`` name
|
|
|
|
|
|
as its argument, in which case the value will be calculated using the
|
|
|
|
|
|
``TimeFormat`` machinery. For this case, one can also pass a ``subfmt``
|
|
|
|
|
|
argument to retrieve the value in another form than ``float``.
|
|
|
|
|
|
> astropy.timeseries
|
|
|
|
|
|
* Keyword ``midpoint_epoch`` is renamed to ``epoch_time``.
|
|
|
|
|
|
> astropy.uncertainty
|
|
|
|
|
|
* ``Distribution`` was rewritten such that it deals better with subclasses.
|
|
|
|
|
|
As a result, Quantity distributions now behave correctly with ``to`` methods
|
|
|
|
|
|
yielding new distributions of the kind expected for the starting distribution,
|
|
|
|
|
|
and ``to_value`` yielding ``NdarrayDistribution`` instances.
|
|
|
|
|
|
> astropy.units
|
|
|
|
|
|
* For consistency with ``ndarray``, scalar ``Quantity.value`` will now return
|
|
|
|
|
|
a numpy scalar rather than a python one. This should help keep track of
|
|
|
|
|
|
precision better, but may lead to unexpected results for the rare cases
|
|
|
|
|
|
where numpy scalars behave differently than python ones (e.g., taking the
|
|
|
|
|
|
square root of a negative number).
|
|
|
|
|
|
* Removed the ``magnitude_zero_points`` module, which was deprecated in
|
|
|
|
|
|
favour of ``astropy.units.photometric`` since 3.1.
|
|
|
|
|
|
* ``EquivalentUnitsList`` now has a ``_repr_html_`` method to output a HTML
|
|
|
|
|
|
table on a call to ``find_equivalent_units`` in Jupyter notebooks.
|
|
|
|
|
|
> astropy.utils
|
|
|
|
|
|
* ``download_file`` and related functions now accept a list of fallback
|
|
|
|
|
|
sources, and they are able to update the cache at the user's request.
|
|
|
|
|
|
* Allow ``astropy.utils.console.ProgressBarOrSpinner.map`` and
|
|
|
|
|
|
``.map_unordered`` to take an argument ``multiprocessing_start_method`` to
|
|
|
|
|
|
control how subprocesses are started; the different methods (``fork``,
|
|
|
|
|
|
``spawn``, and ``forkserver``) have different implications in terms of
|
|
|
|
|
|
security, efficiency, and behavioural anomalies. The option is useful in
|
|
|
|
|
|
particular for cross-platform testing because Windows supports only ``spawn``
|
|
|
|
|
|
while Linux defaults to ``fork``.
|
|
|
|
|
|
* All operations that act on the astropy download cache now take an argument
|
|
|
|
|
|
``pkgname`` that allows one to specify which package's cache to use.
|
|
|
|
|
|
|
|
|
|
|
|
* Removed deprecated ``funcsigs`` and ``futures`` from
|
|
|
|
|
|
``astropy.utils.compat``.
|
|
|
|
|
|
* Removed the deprecated ``astropy.utils.compat.numpy`` module.
|
|
|
|
|
|
* Deprecated ``InheritDocstrings`` as it is natively supported by
|
|
|
|
|
|
Sphinx 1.7 or higher.
|
|
|
|
|
|
* Deprecated ``astropy.utils.timer`` module, which has been moved to
|
|
|
|
|
|
``astroquery.utils.timer`` and will be part of ``astroquery`` 0.4.0.
|
|
|
|
|
|
* Deprecated ``astropy.utils.misc.set_locale`` function, as it is meant for
|
|
|
|
|
|
internal use only.
|
|
|
|
|
|
* The implementation of ``data_info.DataInfo`` has changed (for a considerable
|
|
|
|
|
|
performance boost). Generally, this should not affect simple subclasses, but
|
|
|
|
|
|
because the class now uses ``__slots__`` any attributes on the class have to
|
|
|
|
|
|
be explicitly given a slot.
|
|
|
|
|
|
* ``IERS`` tables now use ``nan`` to mark missing values
|
|
|
|
|
|
(rather than ``1e20``).
|
|
|
|
|
|
> astropy.visualization
|
|
|
|
|
|
* The default ``clip`` value is now ``False`` in ``ImageNormalize``.
|
|
|
|
|
|
* The default ``clip`` value is now ``False`` in ``simple_norm``.
|
|
|
|
|
|
|
|
|
|
|
|
* Infinite values are now excluded when calculating limits in
|
|
|
|
|
|
``ManualInterval`` and ``MinMaxInterval``. They were already excluded in
|
|
|
|
|
|
all other interval classes.

* The ``QuantityAttribute`` class now supports a None default value if a unit

is specified.
|
|
|
|
|
|
* When ``Representation`` classes with the same name are defined, this no
|
|
|
|
|
|
longer leads to a ``ValueError``, but instead to a warning and the removal
|
|
|
|
|
|
of both from the name registry (i.e., one either has to use the class itself
|
|
|
|
|

|
* Fix inaccuracy when converting between TimeDelta and datetime.timedelta.

* Ensure that output from test functions of and comparisons between quantities
|
|
|
|
|
|
can be stored into pre-allocated output arrays (using ``out=array``)

|
|
|
* For the default ``IERS_Auto`` table, which combines IERS A and B values, the
|
|
|
|
|
|
IERS nutation parameters "dX_2000A" and "dY_2000A" are now also taken from
|
|
|
|
|
|
the actual IERS B file rather than from the B values stored in the IERS A
|
|
|
|
|
|
file. Any differences should be negligible for any practical application,
|
|
|
|
|
|
but this may help exactly reproducing results.

|
|
|
|
|
* Calling ``WCSAxes.set_axis_off()`` now correctly turns off drawing the Axes.
|
|
|
|
|
|
|
|
|
|
|
|
* Fix incorrect transformation behavior in ``WCSAxes.plot_coord`` and correctly
|
|
|
|
|
|
handle when input coordinates are not already in spherical representations.
|
|
|
|
|
|
|
|
|
|
|
|
* Fixed ``ImageNormalize`` so that when it is intialized without
|
|
|
|
|
|
``data`` it will still use the input ``interval`` class.
|
|
|
|
|
|
* Fixed ``ImageNormalize`` to handle input data with non-finite
|
|
|
|
|
|
values.
|
|
|
|
|
|
> astropy.wcs
|
|
|
|
|
|
* Fix incorrect value returned by
|
|
|
|
|
|
``wcsapi.HighLevelWCSWrapper.axis_correlation_matrix``.
|
|
|
|
|
|
* Fix NaN-masking of world coordinates when some but not all of the coordinates
|
|
|
|
|
|
were flagged as invalid by WCSLIB. This occurred for example with WCS with >2
|
|
|
|
|
|
dimensions where two of the dimensions were celestial coordinates and pixel
|
|
|
|
|
|
coordinates ouside of the 'sky' were converted to world coordinates -
|
|
|
|
|
|
previously all world coordinates were masked even if uncorrelated with the
|
|
|
|
|
|
celestial axes, but this is no longer the case.
|
|
|
|
|
|
* The default WCS to celestial frame mapping for world coordinate systems that
|
|
|
|
|
|
specify ``TLON`` and ``TLAT`` coordinates will now return an ITRS frame with
|
|
|
|
|
|
the representation class set to ``SphericalRepresentation``. This fixes a bug
|
|
|
|
|
|
that caused ``WCS.pixel_to_world`` to raise an error for such world
|
|
|
|
|
|
coordinate systems.
|
|
|
|
|
|
* ``FITSWCSAPIMixin`` now returns tuples not lists from ``pixel_to_world`` and
|
|
|
|
|
|
``world_to_pixel``.
|
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
|
* Versions of Python <3.6 are no longer supported.
|
|
|
|
|
|
* Matplotlib 2.1 and later is now required.
|
|
|
|
|
|
* Versions of Numpy <1.16 are no longer supported.
|
|
|
|
|
|
* Updated the bundled CFITSIO library to 3.470. See
|
|
|
|
|
|
``cextern/cfitsio/docs/changes.txt`` for additional information.
|
|
|
|
|
|
* The bundled ERFA was updated to version 1.7.0. This is based on
|
|
|
|
|
|
SOFA 20190722. This includes a fix to avoid precision loss for negative
|
|
|
|
|
|
JDs, and also includes additional routines to allow updates to the
|
|
|
|
|
|
leap-second table.
|
|
|
|
|
|
* The default server for the IERS data files has been updated to reflect
|
|
|
|
|
|
long-term downtime of the canonical USNO server.

|
|
|
|
|
|
|
|
|
|
|
- Update to 3.2.3
|
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
|
* Updated IERS A URLs due to USNO prolonged maintenance
|
|
|
|
|
|
- Update to 3.2.2
|
|
|
|
|
|
+ Bug fixes
|
|
|
|
|
|
* astropy.convolution
|
|
|
|
|
|
> Fixed a bug in ``discretize_oversample_1D/2D()`` from
|
|
|
|
|
|
``astropy.convolution.utils``, which might occasionally introduce unexpected
|
|
|
|
|
|
oversampling grid dimensions due to a numerical precision issue.
|
|
|
|
|
|
> Fixed a bug where having a kernel defined using unitless astropy
|
|
|
|
|
|
quantity objects would result in a crash
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
> Fix concatenation of representations for cases where the units were different.
|
|
|
|
|
|
> Check for NaN values in catalog and match coordinates before building and
|
|
|
|
|
|
querying the ``KDTree`` for coordinate matching.
|
|
|
|
|
|
> Fix sky coordinate matching when a dimensionless distance is provided.
|
|
|
|
|
|
> Raise a faster and more meaningful error message when differential data units
|
|
|
|
|
|
are not compatible with a containing representation's units.
|
|
|
|
|
|
> Changed the timescale in ICRS to CIRS from 'tdb' to 'tt' conversion and
|
|
|
|
|
|
vice-versa, as the erfa function that gets called in the process, pnm06a
|
|
|
|
|
|
accepts time in TT.
|
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
|
> Fixed the fast reader when used in parallel and with the multiprocessing
|
|
|
|
|
|
'spawn' method (which is the default on MacOS X with Python 3.8 and later),
|
|
|
|
|
|
and enable parallel fast reader on Windows.
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
> Fixes bug where an invalid TRPOS<n> keyword was being generated for FITS
|
|
|
|
|
|
time column when no location was available.
|
|
|
|
|
|
> Fixed a wrong exception when converting a Table with a unit that is not FITS
|
|
|
|
|
|
compliant and not convertible to a string using ``format='fits'``.
|
|
|
|
|
|
> Fixed an issue with A3DTABLE extension that could not be read.
|
|
|
|
|
|
> Fixed the update of the header when creating GroupsHDU from data.
|
|
|
|
|
|
* astropy.nddata
|
|
|
|
|
|
> Fix to ``add_array``, which now accepts ``array_small`` having dimensions
|
|
|
|
|
|
equal to ``array_large``, instead of only allowing smaller sizes of
|
|
|
|
|
|
arrays.
|
|
|
|
|
|
* astropy.stats
|
|
|
|
|
|
> Fixed ``median_absolute_deviation`` for the case where ``ignore_nan=True``
|
|
|
|
|
|
and an input masked array contained both NaNs and infs.
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
> Comparisons between ``Column`` instances and ``Quantity`` will now
|
|
|
|
|
|
correctly take into account the unit (as was already the case for
|
|
|
|
|
|
regular operations such as addition).
|
|
|
|
|
|
* astropy.time
|
|
|
|
|
|
> Allow ``Time`` to be initialized with an empty value for all formats.
|
|
|
|
|
|
> Fixed a troubling bug in which ``Time`` could loose precision, with deviations
|
|
|
|
|
|
of 300 ns.
|
|
|
|
|
|
* astropy.timeseries
|
|
|
|
|
|
> Fixed handling of ``Quantity`` input data for all methods of
|
|
|
|
|
|
``LombScarge.false_alarm_probabilty``.
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
> Allow conversion of ``Column`` with logarithmic units to a suitable
|
|
|
|
|
|
``Quantity`` subclass if ``subok=True``.
|
|
|
|
|
|
> Ensured that we simplify powers to smaller denominators if that is
|
|
|
|
|
|
consistent within rounding precision.
|
|
|
|
|
|
> Ensured that the powers shown in a unit's repr are always correct,
|
|
|
|
|
|
not oversimplified.
|
|
|
|
|
|
* astropy.utils
|
|
|
|
|
|
> Fixed ``find_api_page`` access by using custom request headers and HTTPS
|
|
|
|
|
|
when version is specified.
|
|
|
|
|
|
> Make ``download_file`` (and by extension ``get_readable_fileobj`` and others)
|
|
|
|
|
|
check the size of downloaded files against the size claimed by the server.
|
|
|
|
|
|
> Fix ``find_current_module`` so that it works properly if astropy is being used
|
|
|
|
|
|
inside a bundle such as that produced by PyInstaller.
|
|
|
|
|
|
> Fix path to renamed classes, which previously included duplicate path/module
|
|
|
|
|
|
information under certain circumstances.
|
|
|
|
|
|
* astropy.visualization
|
|
|
|
|
|
> Silence numpy runtime warnings in ``WCSAxes`` when drawing grids.
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
> Fixed equality test between ``cunit`` where the first element was equal but
|
|
|
|
|
|
the following elements differed.
|
|
|
|
|
|
> Fixed a crash while loading a WCS from headers containing duplicate SIP
|
|
|
|
|
|
keywords.
|
|
|
|
|
|
> Fixed a possible buffer overflow when using too large negative indices for
|
|
|
|
|
|
``cunit`` or ``ctype``
|
|
|
|
|
|
> Fixed reference counting in ``WCSBase.__init__``
|
|
|
|
|
|
> Fix ``SlicedLowLevelWCS`` ``world_to_pixel_values`` and
|
|
|
|
|
|
``pixel_to_world_values`` when inputs need broadcasting to the same shape.
|
|
|
|
|
|
(i.e. when one input is sliced out)
|
|
|
|
|
|
> Fixed a bug that caused ``WCS.array_shape``, ``WCS.pixel_shape`` and
|
|
|
|
|
|
``WCS.pixel_bounds`` to be incorrect after using ``WCS.sub``.
|
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
|
* Fixed a bug that caused files outside of the astropy module directory to be
|
|
|
|
|
|
included as package data, resulting in some cases in errors when doing
|
|
|
|
|
|
repeated builds.

|
|
- Add conflicts with perl-Data-ShowTable
|
|
|
|
|
|
|
Accepting request 717717 from home:TheBlackCat:branches:devel:languages:python:numeric
- Update to 3.2.1
+ Bug fixes
* astropy.io.fits
> Avoid reporting a warning with ``BinTableHDU.from_columns`` with keywords that
are not provided by the user.
> Fix ``Header.fromfile`` to work on FITS files.
> Fix reading of empty ``BinTableHDU`` when stored in a gzip-compressed file.
* astropy.table
> Fix a problem where mask was dropped when creating a ``MaskedColumn``
from a list of ``MaskedArray`` objects.
* astropy.wcs
> Added ``None`` to be displayed as a ``world_axis_physical_types`` in
the ``WCS`` repr, as ``None`` values are now supported in ``APE14``.
- Update to 3.2
+ New Features
* astropy.constants
> Add CODATA 2018 constants but not make them default because the
redefinition of SI units that will follow has not been implemented
yet.
* astropy.coordinates
> New ``BarycentricMeanEcliptic``, ``HeliocentricTrueEcliptic`` and
``GeocentricTrueEcliptic`` frames.
The ecliptic frames are no longer considered experimental.
> The default time scale for epochs like 'J2000' or 'B1975' is now "tt",
which is the correct one for 'J2000' and avoids leap-second warnings
for epochs in the far future or past.
* astropy.extern
> Bundled ``six`` now emits ``AstropyDeprecationWarning``. It will be removed
in 4.0.
* astropy.io.ascii
> IPAC tables now output data types of ``float`` instead of ``double``, or
``int`` instead of ``long``, based on the column ``dtype.itemsize``.
> Update handling of MaskedColumn columns when using the 'data_mask' serialization
method. This can make writing ECSV significantly faster if the data do not
actually have any masked values.
> Fixed a bug that caused newlines to be incorrect when writing out ASCII tables
on Windows (they were ``\r\r\n`` instead of ``\r\n``).
* astropy.io.misc
> Implement serialization of ``TimeDelta`` in ASDF.
> Implement serialization of ``EarthLocation`` in ASDF.
> Implement serialization of ``SkyCoord`` in ASDF.
> Support serialization of Astropy tables with mixin columns in ASDF.
> No warnings when reading HDF5 files with only one table and no ``path=``
argument
> The HDF5 writer will now create a default table instead of raising an
exception when ``path=`` is not specified and when writing to empty/new HDF5
files.
* astropy.io.fits
> Optimize parsing of cards within the ``Header`` class.
> Optimize the parsing of headers to get the structural keywords that are
needed to find extensions. Thanks to this, getting a random HDU from a file
with many extensions is much faster than before, in particular when the
extension headers contain many keywords.
> Change behavior of FITS undefined value in ``Header`` such that ``None``
is used in Python to represent FITS undefined when using dict interface.
``Undefined`` can also be assigned and is translated to ``None``.
Previously setting a header card value to ``None`` resulted in an
empty string field rather than a FITS undefined value.
> Allow ``Header.fromstring`` and ``Card.fromstring`` to accept ``bytes``.
* astropy.io.registry
> Implement ``Table`` reader and writer for ``ASDF``.
> Implement ``Table`` reader and writer methods to wrap ``pandas`` I/O methods
for CSV, Fixed width format, HTML, and JSON.
> Add ``help()`` and ``list_formats()`` methods to unified I/O ``read`` and
``write`` methods. For example ``Table.read.help()`` gives help on available
``Table`` read formats and ``Table.read.help('fits')`` gives detailed
help on the arguments for reading FITS table file.
* astropy.table
> Initializing a table with ``Table(rows=...)``, if the first item is an ``OrderedDict``,
now uses the column order of the first row.
> Added new pprint_all() and pformat_all() methods to Table. These two new
methods print the entire table by default.
> Removed restriction of initializing a Table from a dict with copy=False.
> Improved speed of table row access by a factor of about 2-3. Improved speed
of Table len() by a factor of around 3-10 (depending on the number of columns).
> Improved the Table - pandas ``DataFrame`` interface (``to_pandas()`` and
``from_pandas()``). Mixin columns like ``Time`` and ``Quantity`` can now be
converted to pandas by flattening the columns as necessary to plain
columns. ``Time`` and ``TimeDelta`` columns get converted to
corresponding pandas date or time delta types. The ``DataFrame``
index is now handled in the conversion methods.
> Added ``rename_columns`` method to rename multiple columns in one call.
> Improved Table performance by reducing unnecessary calls to copy and deepcopy,
especially as related to the table and column ``meta`` attributes. Changed the
behavior when slicing a table (either in rows or with a list of column names)
so now the sliced output gets a light (key-only) copy of ``meta`` instead of a
deepcopy. Changed the ``Table.meta`` class-level descriptor so that assigning
directly to ``meta``, e.g. ``tbl.meta = new_meta`` no longer does a deepcopy
and instead just directly assigns the ``new_meta`` object reference. Changed
Table initialization so that input ``meta`` is copied only if ``copy=True``.
> Improved Table slicing performance with internal implementation changes
related to column attribute access and certain input validation.
> Added ``reverse`` argument to the ``sort`` and ``argsort`` methods to allow
sorting in reverse order.
> Improved ``Table.sort()`` performance by removing ``self[keys]`` from code
which is creating deep copies of ``meta`` attribute and adding a new keyword
``names`` in ``get_index()`` to get index by using a list or tuple containing
names of columns.
> Expose ``represent_mixins_as_columns`` as a public function in the
``astropy.table`` subpackage. This previously-private function in the
``table.serialize`` module is used to represent mixin columns in a Table as
one or more plain Column objects.
* astropy.timeseries
> Added a new astropy.timeseries sub-package to represent and manipulate
sampled and binned time series.
> The ``BoxLeastSquares`` and ``LombScargle`` classes have been moved to
``astropy.timeseries.periodograms`` from ``astropy.stats``.
> Added the ability to provide absolute ``Time`` objects to the
``BoxLeastSquares`` and ``LombScargle`` periodogram classes.
> Added model inspection methods (``model_parameters()``, ``design_matrix()``,
and ``offset()``) to ``astropy.timeseries.LombScargle`` class .
* astropy.units
> ``Quantity`` overrides of ``ndarray`` methods such as ``sum``, ``min``,
``max``, which are implemented via reductions, have been removed since they
are dealt with in ``Quantity.__array_ufunc__``. This should not affect
subclasses, but they may consider doing similarly. Note that this
does not include methods that use more complicated python code such as
``mean``, ``std`` and ``var``.
* astropy.visualization
> Added ``CompositeStretch``, which inherits from ``CompositeTransform`` and
also ``BaseStretch`` so that it can be used with ``ImageNormalize``.
> Added a ``log_a`` argument to the ``simple_norm`` method. Similar to the
exposing of the ``asinh_a`` argument for ``AsinhStretch``, the new
``log_a`` argument is now exposed for ``LogStretch``.
* astropy.wcs
> WCSLIB was updated to v 6.2.
This adds support for time-related WCS keywords (WCS Paper VII).
FITS headers containing ``Time`` axis are parsed and the axis is included in
the WCS object.
> The ``OBSGEO`` attribute as expanded to 6 members - ``XYZLBH``.
> Added a new class ``SlicedLowLevelWCS`` in ``astropy.wcs.wcsapi`` that can be
used to slice any WCS that conforms to the ``BaseLowLevelWCS`` API.
> Updated implementation of ``WCS.__getitem__`` and ``WCS.slice`` to now return
a ``SlicedLowLevelWCS`` rather than raising an error when reducing the
dimensionality of the WCS.
+ API Changes
* astropy.coordinates
> ``QuantityAttribute`` no longer has a default value for ``default``. The
previous value of None was misleading as it always was an error.
> The default J2000 has been changed to use be January 1, 2000 12:00 TT instead
of UTC. This is more in line with convention.
* astropy.io.ascii
> IPAC tables now output data types of ``float`` instead of ``double``, or
``int`` instead of ``long``, based on the column ``dtype.itemsize``.
* astropy.io.misc
> Unit equivalencies can now be serialized to ASDF.
* astropy.modeling
> Composition of model classes is deprecated and will be removed in 4.0.
Composition of model instances remain unaffected.
* astropy.stats
> The ``BoxLeastSquares`` and ``LombScargle`` classes have been moved to the
``astropy.timeseries.periodograms`` module and will now emit a deprecation
warning when imported from ``astropy.stats``.
* astropy.table
> Converting an empty table to an array using ``as_array`` method now returns
an empty array instead of ``None``.
> Changed the behavior when slicing a table (either in rows or with a list of column
names) so now the sliced output gets a light (key-only) copy of ``meta`` instead of
a deepcopy. Changed the ``Table.meta`` class-level descriptor so that assigning
directly to ``meta``, e.g. ``tbl.meta = new_meta`` no longer does a deepcopy
and instead just directly assigns the ``new_meta`` object reference. Changed
Table initialization so that input ``meta`` is copied only if ``copy=True``.
> Added a keyword ``names`` in ``Table.as_array()``. If provided this specifies
a list of column names to include for the returned structured array.
* astropy.tests
> Removed ``pytest_plugins`` as they are completely broken for ``pytest>=4``.
> Removed the ``astropy.tests.plugins.config`` plugin and removed the
``--astropy-config-dir`` and ``--astropy-cache-dir`` options from
testing. Please use caching functionality that is natively in ``pytest``.
* astropy.time
> The default time scale for epochs like 'J2000' or 'B1975' is now "tt",
which is the correct one for 'J2000' and avoids leap-second warnings
for epochs in the far future or past.
* astropy.units
> Unit equivalencies can now be introspected.
* astropy.wcs
> The ``world_to_pixel``, ``world_to_array_index*``, ``pixel_to_world*`` and
``array_index_to_world*`` methods now all consistently return scalars, arrays,
or objects not wrapped in a one-element tuple/list when only one scalar,
array, or object (as was previously already the case for ``WCS.pixel_to_world``
and ``WCS.array_index_to_world``).
* astropy.utils
> It is now possible to control the number of cores used by ``ProgressBar.map``
by passing a positive integer as the ``multiprocess`` keyword argument. Use
``True`` to use all cores.
+ Bug Fixes
* astropy.coordinates
> ``BarycentricTrueEcliptic``, ``HeliocentricTrueEcliptic`` and
``GeocentricTrueEcliptic`` now use the correct transformation
(including nutation), whereas the new ``*MeanEcliptic`` classes
use the nutation-free transformation.
> Representations with ``float32`` coordinates can now be transformed,
although the output will always be ``float64``.
> Fixed bug that prevented using differentials with HCRS<->ICRS
transformations.
* astropy.io.ascii
> Fixed a bug where an exception was raised when writing a table which includes
mixin columns (e.g. a Quantity column) and the output format was specified
using the ``formats`` keyword.
* astropy.io.misc
> Fixed bug in ASDF tag that inadvertently introduced dependency on ``pytest``.
* astropy.modeling
> Fixed slowness for certain compound models consisting of large numbers
of multi-input models
> Fixed bugs in fitting of compound models with units.
* astropy.nddata
> Fixed bug in reading multi-extension FITS files written by earlier versions
of ``CCDData``.
> Fixed two errors in the way ``CCDData`` handles FITS files with WCS in the
header. Some of the WCS keywords that should have been removed from the
header were not, potentially leading to FITS files with inconsistent
WCS.
* astropy.table
> Fixed a bug when initializing from an empty list: ``Table([])`` no longer
results in a crash.
> Fixed a bug when initializing from an existing ``Table``. In this case the
input ``meta`` argument was being ignored. Now the input ``meta``, if
supplied, will be used as the ``meta`` for the new ``Table``.
> Fix the conversion of bytes values to Python ``str`` with ``Table.tolist``.
* astropy.time
> Fixed a number of issues to ensure a consistent output type resulting from
multiplication or division involving a ``TimeDelta`` instance. The output is
now always a ``TimeDelta`` if the result is a time unit (like u.s or u.d),
otherwise it will be a ``Quantity``.
> Multiplication between two ``TimeDelta`` instances is now possible, resulting
in a ``Quantity`` with units of time squared (division already correctly
resulted in a dimensionless ``Quantity``).
> Like for comparisons, addition, and subtraction of ``Time`` instances with
with non-time instances, multiplication and division of ``TimeDelta``
instances with incompatible other instances no longer immediately raise an
``UnitsError`` or ``TypeError`` (depending on the other instance), but
rather go through the regular Python mechanism of ``TimeDelta`` returning
``NotImplemented`` (which will lead to a regular ``TypeError`` unless the
other instance can handle ``TimeDelta``).
> Corrected small rounding errors that could cause the ``jd2`` values in
``Time`` to fall outside the range of -0.5 to 0.5.
* astropy.units
> Added a ``Quantity.to_string`` method to add flexibility to the string formatting
of quantities. It produces unadorned or LaTeX strings, and accepts two different
sets of delimiters in the latter case: ``inline`` and ``display``.
> Ensure classes that mimic quantities by having a ``unit`` attribute and/or
``to`` and ``to_value`` methods can be properly used to initialize ``Quantity``
or set ``Quantity`` instance items.
> Add support for ``<<`` to create logarithmic units.
> Add support for the ``clip`` ufunc, which in numpy 1.17 is used to implement
``np.clip``. As part of that, remove the ``Quantity.clip`` method under
numpy 1.17.
> Fix parsing of numerical powers in FITS-compatible units.
* astropy.wcs
> Added a ``PyUnitListProxy_richcmp`` method in ``UnitListProxy`` class to enable
``WCS.wcs.cunit`` equality testing. It helps to check whether the two instances of
``WCS.wcs.cunit`` are equal or not by comparing the data members of
``UnitListProxy`` class
> Fixed ``SlicedLowLevelWCS`` when ``array_shape`` is ``None``.
> Do not attempt to delete repeated distortion keywords multiple times when
loading distortions with ``_read_distortion_kw`` and
``_read_det2im_kw``.
+ Other Changes and Additions
> Update bundled expat to 2.2.6.
> Added instructions for uploading releases to Zenodo.
> The bug fixes to the behaviour of ``TimeDelta`` for multiplcation and
division, which ensure that the output is now always a ``TimeDelta`` if the
result is a time unit (like u.s or u.d) and otherwise a ``Quantity``, imply
that sometimes the output type will be different than it was before.
> For types unrecognized by ``TimeDelta``, multiplication and division now
will consistently return a ``TypeError`` if the other instance cannot handle
``TimeDelta`` (rather than ``UnitsError`` or ``TypeError`` depending on
presumed abilities of the other instance).
> Multiplication between two ``TimeDelta`` instances will no longer result in
an ``OperandTypeError``, but rather result in a ``Quantity`` with units of
time squared (division already correctly resulted in a dimensionless
``Quantity``).
> Made running the tests insensitive to local user configuration when running
the tests in parallel mode or directly with pytest.
> Added a narrative style guide to the documentation for contributor reference.
> Ensure we call numpy equality functions in a way that reduces the number
of ``DeprecationWarning``.
+ Installation
> We now require setuptools 30.3.0 or later to install the core astropy
package.
> We now define groups of dependencies that can be installed with pip, e.g.
``pip install astropy[all]`` (to install all optional dependencies).

|
|
|
|
|
|
|
|
|
|
|
|
- Update to 3.2.1
|
|
|
|
|
|
+ Bug fixes
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
> Avoid reporting a warning with ``BinTableHDU.from_columns`` with keywords that
|
|
|
|
|
|
are not provided by the user.
|
|
|
|
|
|
> Fix ``Header.fromfile`` to work on FITS files.
|
|
|
|
|
|
> Fix reading of empty ``BinTableHDU`` when stored in a gzip-compressed file.
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
> Fix a problem where mask was dropped when creating a ``MaskedColumn``
|
|
|
|
|
|
from a list of ``MaskedArray`` objects.
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
> Added ``None`` to be displayed as a ``world_axis_physical_types`` in
|
|
|
|
|
|
the ``WCS`` repr, as ``None`` values are now supported in ``APE14``.
|
|
|
|
|
|
- Update to 3.2
|
|
|
|
|
|
+ New Features
|
|
|
|
|
|
* astropy.constants
|
|
|
|
|
|
> Add CODATA 2018 constants but not make them default because the
|
|
|
|
|
|
redefinition of SI units that will follow has not been implemented
|
|
|
|
|
|
yet.
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
> New ``BarycentricMeanEcliptic``, ``HeliocentricTrueEcliptic`` and
|
|
|
|
|
|
``GeocentricTrueEcliptic`` frames.
|
|
|
|
|
|
The ecliptic frames are no longer considered experimental.
|
|
|
|
|
|
> The default time scale for epochs like 'J2000' or 'B1975' is now "tt",
|
|
|
|
|
|
which is the correct one for 'J2000' and avoids leap-second warnings
|
|
|
|
|
|
for epochs in the far future or past.
|
|
|
|
|
|
* astropy.extern
|
|
|
|
|
|
> Bundled ``six`` now emits ``AstropyDeprecationWarning``. It will be removed
|
|
|
|
|
|
in 4.0.
|
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
|
> IPAC tables now output data types of ``float`` instead of ``double``, or
|
|
|
|
|
|
``int`` instead of ``long``, based on the column ``dtype.itemsize``.
|
|
|
|
|
|
> Update handling of MaskedColumn columns when using the 'data_mask' serialization
|
|
|
|
|
|
method. This can make writing ECSV significantly faster if the data do not
|
|
|
|
|
|
actually have any masked values.
|
|
|
|
|
|
> Fixed a bug that caused newlines to be incorrect when writing out ASCII tables
|
|
|
|
|
|
on Windows (they were ``\r\r\n`` instead of ``\r\n``).
|
|
|
|
|
|
* astropy.io.misc
|
|
|
|
|
|
> Implement serialization of ``TimeDelta`` in ASDF.
|
|
|
|
|
|
> Implement serialization of ``EarthLocation`` in ASDF.
|
|
|
|
|
|
> Implement serialization of ``SkyCoord`` in ASDF.
|
|
|
|
|
|
> Support serialization of Astropy tables with mixin columns in ASDF.
|
|
|
|
|
|
> No warnings when reading HDF5 files with only one table and no ``path=``
|
|
|
|
|
|
argument
|
|
|
|
|
|
> The HDF5 writer will now create a default table instead of raising an
|
|
|
|
|
|
exception when ``path=`` is not specified and when writing to empty/new HDF5
|
|
|
|
|
|
files.
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
> Optimize parsing of cards within the ``Header`` class.
|
|
|
|
|
|
> Optimize the parsing of headers to get the structural keywords that are
|
|
|
|
|
|
needed to find extensions. Thanks to this, getting a random HDU from a file
|
|
|
|
|
|
with many extensions is much faster than before, in particular when the
|
|
|
|
|
|
extension headers contain many keywords.
|
|
|
|
|
|
> Change behavior of FITS undefined value in ``Header`` such that ``None``
|
|
|
|
|
|
is used in Python to represent FITS undefined when using dict interface.
|
|
|
|
|
|
``Undefined`` can also be assigned and is translated to ``None``.
|
|
|
|
|
|
Previously setting a header card value to ``None`` resulted in an
|
|
|
|
|
|
empty string field rather than a FITS undefined value.
|
|
|
|
|
|
> Allow ``Header.fromstring`` and ``Card.fromstring`` to accept ``bytes``.
|
|
|
|
|
|
* astropy.io.registry
|
|
|
|
|
|
> Implement ``Table`` reader and writer for ``ASDF``.
|
|
|
|
|
|
> Implement ``Table`` reader and writer methods to wrap ``pandas`` I/O methods
|
|
|
|
|
|
for CSV, Fixed width format, HTML, and JSON.
|
|
|
|
|
|
> Add ``help()`` and ``list_formats()`` methods to unified I/O ``read`` and
|
|
|
|
|
|
``write`` methods. For example ``Table.read.help()`` gives help on available
|
|
|
|
|
|
``Table`` read formats and ``Table.read.help('fits')`` gives detailed
|
|
|
|
|
|
help on the arguments for reading FITS table file.
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
> Initializing a table with ``Table(rows=...)``, if the first item is an ``OrderedDict``,
|
|
|
|
|
|
now uses the column order of the first row.
|
|
|
|
|
|
> Added new pprint_all() and pformat_all() methods to Table. These two new
|
|
|
|
|
|
methods print the entire table by default.
|
|
|
|
|
|
> Removed restriction of initializing a Table from a dict with copy=False.
|
|
|
|
|
|
> Improved speed of table row access by a factor of about 2-3. Improved speed
|
|
|
|
|
|
of Table len() by a factor of around 3-10 (depending on the number of columns).
|
|
|
|
|
|
> Improved the Table - pandas ``DataFrame`` interface (``to_pandas()`` and
|
|
|
|
|
|
``from_pandas()``). Mixin columns like ``Time`` and ``Quantity`` can now be
|
|
|
|
|
|
converted to pandas by flattening the columns as necessary to plain
|
|
|
|
|
|
columns. ``Time`` and ``TimeDelta`` columns get converted to
|
|
|
|
|
|
corresponding pandas date or time delta types. The ``DataFrame``
|
|
|
|
|
|
index is now handled in the conversion methods.
|
|
|
|
|
|
> Added ``rename_columns`` method to rename multiple columns in one call.
|
|
|
|
|
|
> Improved Table performance by reducing unnecessary calls to copy and deepcopy,
|
|
|
|
|
|
especially as related to the table and column ``meta`` attributes. Changed the
|
|
|
|
|
|
behavior when slicing a table (either in rows or with a list of column names)
|
|
|
|
|
|
so now the sliced output gets a light (key-only) copy of ``meta`` instead of a
|
|
|
|
|
|
deepcopy. Changed the ``Table.meta`` class-level descriptor so that assigning
|
|
|
|
|
|
directly to ``meta``, e.g. ``tbl.meta = new_meta`` no longer does a deepcopy
|
|
|
|
|
|
and instead just directly assigns the ``new_meta`` object reference. Changed
|
|
|
|
|
|
Table initialization so that input ``meta`` is copied only if ``copy=True``.
|
|
|
|
|
|
> Improved Table slicing performance with internal implementation changes
|
|
|
|
|
|
related to column attribute access and certain input validation.
|
|
|
|
|
|
> Added ``reverse`` argument to the ``sort`` and ``argsort`` methods to allow
|
|
|
|
|
|
sorting in reverse order.
|
|
|
|
|
|
> Improved ``Table.sort()`` performance by removing ``self[keys]`` from code
|
|
|
|
|
|
which is creating deep copies of ``meta`` attribute and adding a new keyword
|
|
|
|
|
|
``names`` in ``get_index()`` to get index by using a list or tuple containing
|
|
|
|
|
|
names of columns.
|
|
|
|
|
|
> Expose ``represent_mixins_as_columns`` as a public function in the
|
|
|
|
|
|
``astropy.table`` subpackage. This previously-private function in the
|
|
|
|
|
|
``table.serialize`` module is used to represent mixin columns in a Table as
|
|
|
|
|
|
one or more plain Column objects.
|
|
|
|
|
|
* astropy.timeseries
|
|
|
|
|
|
> Added a new astropy.timeseries sub-package to represent and manipulate
|
|
|
|
|
|
sampled and binned time series.
|
|
|
|
|
|
> The ``BoxLeastSquares`` and ``LombScargle`` classes have been moved to
|
|
|
|
|
|
``astropy.timeseries.periodograms`` from ``astropy.stats``.
|
|
|
|
|
|
> Added the ability to provide absolute ``Time`` objects to the
|
|
|
|
|
|
``BoxLeastSquares`` and ``LombScargle`` periodogram classes.
|
|
|
|
|
|
> Added model inspection methods (``model_parameters()``, ``design_matrix()``,
|
|
|
|
|
|
and ``offset()``) to ``astropy.timeseries.LombScargle`` class .
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
> ``Quantity`` overrides of ``ndarray`` methods such as ``sum``, ``min``,
|
|
|
|
|
|
``max``, which are implemented via reductions, have been removed since they
|
|
|
|
|
|
are dealt with in ``Quantity.__array_ufunc__``. This should not affect
|
|
|
|
|
|
subclasses, but they may consider doing similarly. Note that this
|
|
|
|
|
|
does not include methods that use more complicated python code such as
|
|
|
|
|
|
``mean``, ``std`` and ``var``.
|
|
|
|
|
|
* astropy.visualization
|
|
|
|
|
|
> Added ``CompositeStretch``, which inherits from ``CompositeTransform`` and
|
|
|
|
|
|
also ``BaseStretch`` so that it can be used with ``ImageNormalize``.
|
|
|
|
|
|
> Added a ``log_a`` argument to the ``simple_norm`` method. Similar to the
|
|
|
|
|
|
exposing of the ``asinh_a`` argument for ``AsinhStretch``, the new
|
|
|
|
|
|
``log_a`` argument is now exposed for ``LogStretch``.
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
> WCSLIB was updated to v 6.2.
|
|
|
|
|
|
This adds support for time-related WCS keywords (WCS Paper VII).
|
|
|
|
|
|
FITS headers containing ``Time`` axis are parsed and the axis is included in
|
|
|
|
|
|
the WCS object.
|
|
|
|
|
|
> The ``OBSGEO`` attribute as expanded to 6 members - ``XYZLBH``.
|
|
|
|
|
|
> Added a new class ``SlicedLowLevelWCS`` in ``astropy.wcs.wcsapi`` that can be
|
|
|
|
|
|
used to slice any WCS that conforms to the ``BaseLowLevelWCS`` API.
|
|
|
|
|
|
> Updated implementation of ``WCS.__getitem__`` and ``WCS.slice`` to now return
|
|
|
|
|
|
a ``SlicedLowLevelWCS`` rather than raising an error when reducing the
|
|
|
|
|
|
dimensionality of the WCS.
|
|
|
|
|
|
+ API Changes
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
> ``QuantityAttribute`` no longer has a default value for ``default``. The
|
|
|
|
|
|
previous value of None was misleading as it always was an error.
|
|
|
|
|
|
> The default J2000 has been changed to use be January 1, 2000 12:00 TT instead
|
|
|
|
|
|
of UTC. This is more in line with convention.
|
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
|
> IPAC tables now output data types of ``float`` instead of ``double``, or
|
|
|
|
|
|
``int`` instead of ``long``, based on the column ``dtype.itemsize``.
|
|
|
|
|
|
* astropy.io.misc
|
|
|
|
|
|
> Unit equivalencies can now be serialized to ASDF.
|
|
|
|
|
|
* astropy.modeling
|
|
|
|
|
|
> Composition of model classes is deprecated and will be removed in 4.0.
|
|
|
|
|
|
Composition of model instances remain unaffected.
|
|
|
|
|
|
* astropy.stats
|
|
|
|
|
|
> The ``BoxLeastSquares`` and ``LombScargle`` classes have been moved to the
|
|
|
|
|
|
``astropy.timeseries.periodograms`` module and will now emit a deprecation
|
|
|
|
|
|
warning when imported from ``astropy.stats``.
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
> Converting an empty table to an array using ``as_array`` method now returns
|
|
|
|
|
|
an empty array instead of ``None``.
|
|
|
|
|
|
> Changed the behavior when slicing a table (either in rows or with a list of column
|
|
|
|
|
|
names) so now the sliced output gets a light (key-only) copy of ``meta`` instead of
|
|
|
|
|
|
a deepcopy. Changed the ``Table.meta`` class-level descriptor so that assigning
|
|
|
|
|
|
directly to ``meta``, e.g. ``tbl.meta = new_meta`` no longer does a deepcopy
|
|
|
|
|
|
and instead just directly assigns the ``new_meta`` object reference. Changed
|
|
|
|
|
|
Table initialization so that input ``meta`` is copied only if ``copy=True``.
|
|
|
|
|
|
> Added a keyword ``names`` in ``Table.as_array()``. If provided this specifies
|
|
|
|
|
|
a list of column names to include for the returned structured array.
|
|
|
|
|
|
* astropy.tests
|
|
|
|
|
|
> Removed ``pytest_plugins`` as they are completely broken for ``pytest>=4``.
|
|
|
|
|
|
> Removed the ``astropy.tests.plugins.config`` plugin and removed the
|
|
|
|
|
|
``--astropy-config-dir`` and ``--astropy-cache-dir`` options from
|
|
|
|
|
|
testing. Please use caching functionality that is natively in ``pytest``.
|
|
|
|
|
|
* astropy.time
|
|
|
|
|
|
> The default time scale for epochs like 'J2000' or 'B1975' is now "tt",
|
|
|
|
|
|
which is the correct one for 'J2000' and avoids leap-second warnings
|
|
|
|
|
|
for epochs in the far future or past.
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
> Unit equivalencies can now be introspected.
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
> The ``world_to_pixel``, ``world_to_array_index*``, ``pixel_to_world*`` and
|
|
|
|
|
|
``array_index_to_world*`` methods now all consistently return scalars, arrays,
|
|
|
|
|
|
or objects not wrapped in a one-element tuple/list when only one scalar,
|
|
|
|
|
|
array, or object (as was previously already the case for ``WCS.pixel_to_world``
|
|
|
|
|
|
and ``WCS.array_index_to_world``).
|
|
|
|
|
|
* astropy.utils
|
|
|
|
|
|
> It is now possible to control the number of cores used by ``ProgressBar.map``
|
|
|
|
|
|
by passing a positive integer as the ``multiprocess`` keyword argument. Use
|
|
|
|
|
|
``True`` to use all cores.
|
|
|
|
|
|
+ Bug Fixes
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
> ``BarycentricTrueEcliptic``, ``HeliocentricTrueEcliptic`` and
|
|
|
|
|
|
``GeocentricTrueEcliptic`` now use the correct transformation
|
|
|
|
|
|
(including nutation), whereas the new ``*MeanEcliptic`` classes
|
|
|
|
|
|
use the nutation-free transformation.
|
|
|
|
|
|
> Representations with ``float32`` coordinates can now be transformed,
|
|
|
|
|
|
although the output will always be ``float64``.
|
|
|
|
|
|
> Fixed bug that prevented using differentials with HCRS<->ICRS
|
|
|
|
|
|
transformations.
|
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
|
> Fixed a bug where an exception was raised when writing a table which includes

|
|
using the ``formats`` keyword.
|
|
|
|
|
|
* astropy.io.misc
|
|
|
|
|
|
> Fixed bug in ASDF tag that inadvertently introduced dependency on ``pytest``.
|
|
|
|
|
|
* astropy.modeling
|
|
|
|
|
|
> Fixed slowness for certain compound models consisting of large numbers
|
|

|
|
|
of multi-input models
|
|
|
|
|
|
> Fixed bugs in fitting of compound models with units.
|
|
|
|
|
|
* astropy.nddata
|
|
|
|
|
|
> Fixed bug in reading multi-extension FITS files written by earlier versions
|
|
|
|
|
|
of ``CCDData``.
|
|
|
|
|
|
> Fixed two errors in the way ``CCDData`` handles FITS files with WCS in the
|
|
|
|
|
|
header. Some of the WCS keywords that should have been removed from the
|
|
|
|
|
|
header were not, potentially leading to FITS files with inconsistent
|
|
|
|
|
|
WCS.
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
> Fixed a bug when initializing from an empty list: ``Table([])`` no longer
|
|
|
|
|
|
results in a crash.
|
|
|
|
|
|
> Fixed a bug when initializing from an existing ``Table``. In this case the
|
|
|
|
|
|
input ``meta`` argument was being ignored. Now the input ``meta``, if
|
|
|
|
|
|
supplied, will be used as the ``meta`` for the new ``Table``.
|
|
|
|
|
|
> Fix the conversion of bytes values to Python ``str`` with ``Table.tolist``.
|
|
|
|
|
|
* astropy.time
|
|
|
|
|
|
> Fixed a number of issues to ensure a consistent output type resulting from
|
|
|
|
|
|
multiplication or division involving a ``TimeDelta`` instance. The output is
|
|
|
|
|
|
now always a ``TimeDelta`` if the result is a time unit (like u.s or u.d),
|
|
|
|
|
|
otherwise it will be a ``Quantity``.
|
|
|
|
|
|
> Multiplication between two ``TimeDelta`` instances is now possible, resulting
|
|
|
|
|
|
in a ``Quantity`` with units of time squared (division already correctly
|
|
|
|
|
|
resulted in a dimensionless ``Quantity``).
|
|
|
|
|
|
> Like for comparisons, addition, and subtraction of ``Time`` instances with
|
|
|
|
|
|
with non-time instances, multiplication and division of ``TimeDelta``
|
|
|
|
|
|
instances with incompatible other instances no longer immediately raise an
|
|
|
|
|
|
``UnitsError`` or ``TypeError`` (depending on the other instance), but
|
|
|
|
|
|
rather go through the regular Python mechanism of ``TimeDelta`` returning
|
|
|
|
|
|
``NotImplemented`` (which will lead to a regular ``TypeError`` unless the
|
|
|
|
|
|
other instance can handle ``TimeDelta``).
|
|
|
|
|
|
> Corrected small rounding errors that could cause the ``jd2`` values in
|
|
|
|
|
|
``Time`` to fall outside the range of -0.5 to 0.5.
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
> Added a ``Quantity.to_string`` method to add flexibility to the string formatting
|
|
|
|
|
|
of quantities. It produces unadorned or LaTeX strings, and accepts two different
|
|
|
|
|
|
sets of delimiters in the latter case: ``inline`` and ``display``.
|
|
|
|
|
|
> Ensure classes that mimic quantities by having a ``unit`` attribute and/or
|
|
|
|
|
|
``to`` and ``to_value`` methods can be properly used to initialize ``Quantity``
|
|
|
|
|
|
or set ``Quantity`` instance items.
|
|
|
|
|
|
> Add support for ``<<`` to create logarithmic units.
|
|
|
|
|
|
> Add support for the ``clip`` ufunc, which in numpy 1.17 is used to implement
|
|
|
|
|
|
``np.clip``. As part of that, remove the ``Quantity.clip`` method under
|
|
|
|
|
|
numpy 1.17.
|
|
|
|
|
|
> Fix parsing of numerical powers in FITS-compatible units.
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
> Added a ``PyUnitListProxy_richcmp`` method in ``UnitListProxy`` class to enable
|
|
|
|
|
|
``WCS.wcs.cunit`` equality testing. It helps to check whether the two instances of
|
|
|
|
|
|
``WCS.wcs.cunit`` are equal or not by comparing the data members of
|
|
|
|
|
|
``UnitListProxy`` class
|
|
|
|
|
|
> Fixed ``SlicedLowLevelWCS`` when ``array_shape`` is ``None``.
|
|
|
|
|
|
> Do not attempt to delete repeated distortion keywords multiple times when
|
|
|
|
|
|
loading distortions with ``_read_distortion_kw`` and
|
|
|
|
|
|
``_read_det2im_kw``.

|
|
+ Other Changes and Additions
|
|
|
|
|
|
> Update bundled expat to 2.2.6.
|
|
|
|
|
|
> Added instructions for uploading releases to Zenodo.
|
|
|
|
|
|
> The bug fixes to the behaviour of ``TimeDelta`` for multiplcation and
|
|
|
|
|
|
division, which ensure that the output is now always a ``TimeDelta`` if the
|
|
|
|
|
|
result is a time unit (like u.s or u.d) and otherwise a ``Quantity``, imply
|
|
|
|
|
|
that sometimes the output type will be different than it was before.
|
|
|
|
|
|
> For types unrecognized by ``TimeDelta``, multiplication and division now
|
|
|
|
|
|
will consistently return a ``TypeError`` if the other instance cannot handle
|
|
|
|
|
|
``TimeDelta`` (rather than ``UnitsError`` or ``TypeError`` depending on
|
|
|
|
|
|
presumed abilities of the other instance).
|
|
|
|
|
|
> Multiplication between two ``TimeDelta`` instances will no longer result in
|
|
|
|
|
|
an ``OperandTypeError``, but rather result in a ``Quantity`` with units of
|
|
|
|
|
|
time squared (division already correctly resulted in a dimensionless
|
|
|
|
|
|
``Quantity``).
|
|
|
|
|
|
> Made running the tests insensitive to local user configuration when running
|
|
|
|
|
|
the tests in parallel mode or directly with pytest.
|
|
|
|
|
|
> Added a narrative style guide to the documentation for contributor reference.
|
|
|
|
|
|
> Ensure we call numpy equality functions in a way that reduces the number
|
|
|
|
|
|
of ``DeprecationWarning``.
|
|
|
|
|
|
+ Installation
|
|
|
|
|
|
> We now require setuptools 30.3.0 or later to install the core astropy
|
|
|
|
|
|
package.
|
|
|
|
|
|
> We now define groups of dependencies that can be installed with pip, e.g.
|
|
|
|
|
|
``pip install astropy[all]`` (to install all optional dependencies).

+ New Features
> astropy.convolution
* ``convolve`` now accepts any array-like input, not just ``numpy.ndarray`` or
lists. [#7303]
* ``convolve`` Now raises AstropyUserWarning if nan_treatment='interpolate' and
preserve_nan=False and NaN values are present post convolution. [#8088]
> astropy.coordinates
* The ``SkyCoord.from_name`` constructor now has the ability to create
coordinate objects by parsing object catalogue names that have embedded
J-coordinates. [#7830]
* The new function ``make_transform_graph_docs`` can be used to create a
docstring graph from a custom ``TransformGraph`` object. [#7135]
* ``KDTree`` for catalog matching is now built with sliding midpoint rule
rather than standard. In code, this means setting ``compact_nodes=False``
and ``balanced_tree=False`` in ``cKDTree``. The sliding midpoint rule is much
more suitable for catalog matching, and results in 1000x speedup in some
cases. [#7324]
* Additional information about a site loaded from the Astropy sites registry is
now available in ``EarthLocation.info.meta``. [#7857]
* Added a ``concatenate_representations`` function to combine coordinate
representation data and any associated differentials. [#7922]
* ``BaseCoordinateFrame`` will now check for a method named
``_astropy_repr_in_frame`` when constructing the string forms of attributes.
Allowing any class to control how ``BaseCoordinateFrame`` represents it when
it is an attribute of a frame. [#7745]
* Some rarely-changed attributes of frame classes are now cached, resulting in
speedups (up to 50% in some cases) when creating new scalar frame or
``SkyCoord`` objects. [#7949, #5952]
* Added a ``directional_offset_by`` method to ``SkyCoord`` that computes a new
coordinate given a coordinate, position angle, and angular separation [#5727]
> astropy.cosmology
* The default cosmology has been changed from ``WMAP9`` to ``Planck15``. [#8123]
* Distance calculations with ``LambaCDM`` with no radiation (T_CMB0=0)
are now 20x faster by using elliptic integrals for non-flat cases. [#7155]
* Distance calculations with ``FlatLambaCDM`` with no radiation (T_CMB0=0)
are now 20x faster by using the hypergeometric function solution
for this special case. [#7087]
* Age calculations with ``FlatLambdaCDM`` with no radiation (Tcmb0=0)
are now 1000x faster by using analytic solutions instead of integrating.
[#7117]
> astropy.io.ascii
* Latex reader now ignores ``\toprule``, ``\midrule``, and ``\bottomrule``
commands. [#7349]
* Added the RST (Restructured-text) table format and the fast version of the
RDB reader to the set of formats that are guessed by default. [#5578]
* The read trace (used primarily for debugging) now includes guess argument
sets that were skipped entirely e.g. for not supporting user-supplied kwargs.
All guesses thus removed from ``filtered_guess_kwargs`` are now listed as
"Disabled" at the beginning of the trace. [#5578]
* Emit a warning when reading an ECSV file without specifying the ``format``
and without PyYAML installed. Previously this silently fell through to
parsing as a basic format file and the file metadata was lost. [#7580]
* Optionally allow writing masked columns to ECSV with the mask explicitly
specified as a separate column instead of marking masked elements with ""
(empty string). This allows handling the case of a masked string column
with "" data rows. [#7481]
> astropy.io.misc
* Added support for saving all representation classes and many coordinate
frames to the asdf format. [#7079]
* Added support for saving models with units to the asdf format. [#7237]
* Added a new ``character_as_bytes`` keyword to the HDF5 Table reading
function to control whether byte string columns in the HDF5 file
are left as bytes or converted to unicode. The default is to read
as bytes (``character_as_bytes=True``). [#7024, #8017]
> astropy.io.fits
* ``HDUList.pop()`` now accepts string and tuple extension name
specifications. [#7236]
* Add an ``ignore_hdus`` keyword to ``FITSDiff`` to allow ignoring HDUs by
NAME when diffing two FITS files [#7538]
* Optionally allow writing masked columns to FITS with the mask explicitly
specified as a separate column instead of using the FITS standard of
certain embedded null values (``NaN`` for float, ``TNULL`` for integers).
This can be used to work around limitations in the FITS standard. [#7481]
* All time coordinates can now be written to and read from FITS binary tables,
including those with vectorized locations. [#7430]
* The ``fitsheader`` command line tool now supports a ``dfits+fitsort`` mode,
and the dotted notation for keywords (e.g. ``ESO.INS.ID``). [#7240]
* Fall back to reading arrays using mode='denywrite' if mode='readonly' fails
when using memory-mapping. This solves cases on some platforms when the
available address space was less than the file size (even when using memory
mapping). [#7926]
> astropy.modeling
* Add a ``Multiply`` model which preserves unit through evaluate, unlike
``Scale`` which is dimensionless. [#7210]
* Add a ``uses_quantity`` property to ``Model`` which allows introspection of if
the ``Model`` can accept ``Quantity`` objects. [#7417]
* Add a ``separability_matrix`` function which returns the correlation matrix
of inputs and outputs. [#7803]
* Fixed compatibility of ``JointFitter`` with the latest version of Numpy. [#7984]
* Add ``prior`` and ``posterior`` constraints to modeling parameters. These are
not used by any current fitters, but are provided to allow user code to
experiment with Bayesian fitters. [#7558]
> astropy.nddata
* ``NDUncertainty`` objects now have a ``quantity`` attribute for simple
conversion to quantities. [#7704]
* Add a ``bitmask`` module that provides functions for manipulating bitmasks
and data quality (DQ) arrays. [#7944]
> astropy.stats
* Add an ``astropy.stats.bls`` module with an implementation of the "box least
squares" periodogram that is commonly used for discovering transiting
exoplanets and eclipsing binaries. [#7391]
> astropy.table
* Added support for full use of ``Time`` mixin column for join, hstack, and
vstack table operations. [#6888]
* Added a new table index engine, ``SCEngine``, based on the Sorted Containers
package. [#7574]
* Add a new keyword argument ``serialize_method`` to ``Table.write`` to
control how ``Time`` and ``MaskedColumn`` columns are written. [#7481]
* Allow mixin columns to be used in table ``group`` and ``unique``
functions. This applies to both the key columns and the other data
columns. [#7712]
* Added support for stacking ``Column``, mixin column (e.g. ``Quantity``,
``Time``) or column-like objects. [#7674]
* Added support for inserting a row into a Table that has ``Time`` or
``TimeDelta`` column(s). [#7897]
> astropy.tests
* Added an option ``--readonly`` to the test command to change the
permissions on the temporary installation location to read-only. [#7598]
> astropy.time
* Allow array-valued ``Time`` object to be modified in place. [#6028]
* Added support for missing values (masking) to the ``Time`` class. [#6028]
* Added supper for a 'local' time scale (for free-running clocks, etc.),
and round-tripping to the corresponding FITS time scale. [#7122]
* Added `datetime.timedelta` format class for ``TimeDelta``. [#7441]
* Added ``strftime`` and ``strptime`` methods to ``Time`` class.
These methods are similar to those in the Python standard library
`time` package and provide flexible input and output formatting. [#7323]
* Added ``datetime64`` format to the ``Time`` class to support working with
``numpy.datetime64`` dtype arrays. [#7361]
* Add fractional second support for ``strftime`` and ``strptime`` methods
of ``Time`` class. [#7705]
* Added an ``insert`` method to allow inserting one or more values into a
``Time`` or ``TimeDelta`` object. [#7897]
* Remove timescale from string version of FITS format time string.
The timescale is not part of the FITS standard and should not be included.
This change may cause some compatibility issues for code that relies on
round-tripping a FITS format string with a timescale. Strings generated
from previous versions of this package are still understood but a
DeprecationWarning will be issued. [#7870]
> astropy.uncertainty
* This sub-package was added as a "preview" (i.e. API unstable), containing
the ``Distribution`` class and associated convenience functions. [#6945]
> astropy.units
* Add complex numbers support for ``Quantity._repr_latex_``. [#7676]
* Add ``thermodynamic_temperature`` equivalency to convert between
Jy/beam and "thermodynamic temperature" for cosmology. [#7054]
* Add millibar unit. [#7863]
* Add maggy and nanomaggy unit, as well as associated ``zero_point_flux``
equivalency. [#7891]
* ``AB`` and ``ST`` are now enabled by default, and have alternate names
``ABflux`` and ``STflux``. [#7891]
* Added ``littleh`` unit and associated ``with_H0`` equivalency. [#7970]
> astropy.visualization
* Added ``imshow_norm`` function, which combines imshow and creation of a
``ImageNormalize`` object. [#7785]
> astropy.visualization.wcsaxes
* Add support for setting ``set_separator(None)`` in WCSAxes to use default
separators. [#7570]
* Added two keyword argument options to ``CoordinateHelper.set_format_unit``:
``decimal`` can be used to specify whether to use decimal formatting for the
labels (by default this is False for degrees and hours and True otherwise),
and ``show_decimal_unit`` can be used to determine whether the units should be
shown for decimal labels. [#7318]
* Added documentation for ``transform=`` and ``coord_meta=``. [#7698]
* Allow ``coord_meta=`` to optionally include ``format_unit=``. [#7848]
* Add support for more rcParams related to the grid, ticks, and labels, and
should work with most built-in Matplotlib styles. [#7961]
* Improved rendering of outward-facing ticks. [#7961]
* Add support for ``tick_params`` (which is a standard Matplotlib
function/method) on both the ``WCSAxes`` class and the individual
``CoordinateHelper`` classes. Note that this is provided for compatibility
with Matplotlib syntax users may be familiar with, but it is not the
preferred way to change settings. Instead, methods such as ``set_ticks``
should be preferred. [#7969]
* Moved the argument ``exclude_overlapping`` from ``set_ticks`` to
``set_ticklabel``. [#7969]
* Added a ``pad=`` argument to ``set_ticklabel`` to provide a way to control
the padding between ticks and tick labels. [#7969]
* Added support for setting the tick direction in ``set_ticks`` using the
``direction=`` keyword argument. [#7969]
> astropy.wcs
* Map ITRS frames to terrestrial WCS coordinates. This will make it possible to
use WCSAxes to make figures that combine both celestial and terrestrial
features. An example is plotting the coordinates of an astronomical transient
over an all- sky satellite image to illustrate the position relative to the
Earth at the time of the event. The ITRS frame is identified with WCSs that
use the ``TLON-`` and ``TLAT-`` coordinate types. There are several examples
of WCSs where this syntax is used to describe terrestrial coordinate systems:
Section 7.4.1 of `WCS in FITS "Paper II" <http://adsabs.harvard.edu/abs/2002A%26A...395.1077C>`_
and the `WCSTools documentation <http://tdc-www.harvard.edu/software/wcstools/wcstools.multiwcs.html>`_.
[#6990]
* Added the abstract base class for the low-level WCS API described in APE 14
(https://doi.org/10.5281/zenodo.1188875). [#7325]
* Add ``WCS.contains()`` function to check if the WCS footprint contains a given sky coordinate. [#7273]
* Added the abstract base class for the high-level WCS API described in APE 14
(https://doi.org/10.5281/zenodo.1188875). [#7325]
* Added the high-level wrapper class for low-level WCS objects as described in
APE 14 (https://doi.org/10.5281/zenodo.1188875). [#7326]
* Added a new property ``WCS.has_distortion``. [#7326]
* Deprecated ``_naxis1`` and ``_naxis2`` in favor of ``pixel_shape``. [#7973]
* Added compatibility to wcslib version 6. [#8093]
+ API Changes
> astropy.convolution
* ``kernel`` can now be a tuple. [#7561]
* Not technically an API changes, however, the docstring indicated that ``boundary=None``
was the default when actually it is ``boundary='fill'``. The docstring has been corrected,
however, someone may interpret this as an API change not realizing that nothing has actually
changed. [#7293]
* ``interpolate_replace_nans()`` can no longer accept the keyword argument
``preserve_nan``. It is explicitly set to ``False``. [#8088]
> astropy.coordinates
* Fixed ``astropy.coordinates.concatenate`` to include velocity data in the
concatenation. [#7922]
* Changed the name of the single argument to ``Frame.realize_frame()`` from the
(incorrect) ``representation_type`` to ``data``. [#7923]
* Negative parallaxes passed to ``Distance()`` now raise an error by default
(``allow_negative=False``), or are converted to NaN values with a warning
(``allow_negative=True``). [#7988]
* Negating a ``SphericalRepresentation`` object now changes the angular
coordinates (by rotating 180º) instead of negating the distance. [#7988]
* Creation of new frames now generally creates copies of frame attributes,
rather than inconsistently either copying or making references. [#8204]
* The frame class method ``is_equivalent_frame`` now checks for equality of
components to determine if a frame is the same when it has frame attributes
that are representations, rather than checking if they are the same
object. [#8218]
> astropy.io.ascii
* If a fast reader is explicitly selected (e.g. ``fast_reader='force'``) and
options which are incompatible with the fast reader are provided
(e.g. ``quotechar='##'``) then now a ``ParameterError`` exception will be
raised. [#5578]
* The fast readers will now raise ``InconsistentTableError`` instead of
``CParserError`` if the number of data and header columns do not match.
[#5578]
* Changed a number of ``ValueError`` exceptions to ``InconsistentTableError``
in places where the exception is related to parsing a table which is
inconsistent with the specified table format. Note that
``InconsistentTableError`` inherits from ``ValueError`` so no user code
changes are required. [#7425]
> astropy.io.fits
* The ``fits.table_to_hdu()`` function will translate any column ``format``
attributes to a TDISPn format string, if possible, and store it as a TDISPn
keyword in the ``HDU`` header. [#7226]
> astropy.modeling
* Change the order of the return values from ``FittingWithOutlierRemoval``,
such that ``fitted_model`` comes first, for consistency with other fitters.
For the second value, return only a boolean outlier ``mask``, instead of the
previous ``MaskedArray`` (which included a copy of the input data that was
both redundant and inadvertently corrupted at masked points). Return a
consistent type for the second value when ``niter=0``. [#7407]
* Set the minimum value for the ``bolometric_flux`` parameter of the
``BlackBody1D`` model to zero. [#7045]
> astropy.nddata
* Add two new uncertainty classes, ``astropy.nddata.VarianceUncertainty`` and
``astropy.nddata.InverseVariance``. [#6971]
> astropy.stats
* String values can now be used for the ``cenfunc`` and ``stdfunc``
keywords in the ``SigmaClip`` class and ``sigma_clip`` and
``sigma_clipped_stats`` functions. [#7478]
* The ``SigmaClip`` class and ``sigma_clip`` and
``sigma_clipped_stats`` functions now have a ``masked`` keyword,
which can be used to return either a masked array (default) or an
ndarray with the min/max values. [#7478]
* The ``iters`` keyword has been renamed (and deprecated) to
``maxiters`` in the ``SigmaClip`` class and ``sigma_clip`` and
``sigma_clipped_stats`` functions. [#7478]
> astropy.table
* ``Table.read()`` on a FITS binary table file will convert any TDISPn header
keywords to a Python formatting string when possible, and store it in the
column ``format`` attribute. [#7226]
* No values provided to stack will now raise ``ValueError`` rather than
``TypeError``. [#7674]
> astropy.tests
* ``from astropy.tests.helper import *`` no longer includes
``quantity_allclose``. However,
``from astropy.tests.helper import quantity_allclose`` would still work.
[#7381]
* ``warnings_to_ignore_by_pyver`` option in
``enable_deprecations_as_exceptions()`` now takes ``None`` as key.
Any deprecation message that is mapped to ``None`` will be ignored
regardless of the Python version. [#7790]
> astropy.time
* Added the ability to use ``local`` as time scale in ``Time`` and
``TimeDelta``. [#6487]
* Comparisons, addition, and subtraction of ``Time`` instances with non-time
instances will now return ``NotImplemented`` rather than raise the
``Time``-specific ``OperandTypeError``. This will generally lead to a
regular ``TypeError``. As a result, ``OperandTypeError`` now only occurs if
the operation is between ``Time`` instances of incompatible type or scale.
[#7584]
> astropy.units
* In ``UnitBase.compose()``, if a sequence (list|tuple) is passed in to
``units``, the default for ``include_prefix_units`` is set to
`True`, so that no units get ignored. [#6957]
* Negative parallaxes are now converted to NaN values when using the
``parallax`` equivalency. [#7988]
> astropy.utils
* ``InheritDocstrings`` now also works on class properties. [#7166]
* ``diff_values()``, ``report_diff_values()``, and ``where_not_allclose()``
utility functions are moved from ``astropy.io.fits.diff``. [#7444]
* ``invalidate_caches()`` has been removed from the
``astropy.utils.compat`` namespace, use it directly from ``importlib``. [#7872]
> astropy.visualization
* In ``ImageNormalize``, the default for ``clip`` is set to ``True``. [#7800]
* Changed ``AsymmetricPercentileInterval`` and ``MinMaxInterval`` to
ignore NaN values in arrays. [#7360]
* Automatically default to using ``grid_type='contours'`` in WCSAxes when using
a custom ``Transform`` object if the transform has no inverse. [#7847]
+ Performance Improvements
* Reduced import time by more cautious use of the standard library. [#7647]
> astropy.convolution
* Major performance overhaul to ``convolve()``. [#7293]
* ``convolve()``: Boundaries ``fill``, ``extend``, and ``wrap`` now use a single
implementation that pads the image with the correct boundary values before convolving.
The runtimes of these three were significantly skewed. They now have
equivalent runtimes that are also faster than before due to performant contiguous
memory access. However, this does increase the memory footprint as an entire
new image array is required plus that needed for the padded region.[#7293]
* ``convolve()``: Core computation ported from Cython to C. Several optimization
techniques have been implemented to achieve performance gains, e.g. compiler
hoisting, and vectorization, etc. Compiler optimization level ``-O2`` required for
hoisting and ``-O3`` for vectorization. [#7293]
* ``convolve()``: ``nan_treatment=‘interpolate’`` was slow to compute irrespective of
whether any NaN values exist within the array. The input array is now
checked for NaN values and interpolation is disabled if non are found. This is a
significant performance boost for arrays without NaN values. [#7293]
> astropy.coordinates
* Sped up creating SkyCoord objects by a factor of ~2 in some cases. [#7615]
* Sped up getting xyz vectors from ``CartesianRepresentation`` (which
is used a lot internally). [#7638]
* Sped up transformations and some representation methods by replacing
python code with (compiled) ``erfa`` ufuncs. [#7639]
* Sped up adding differential (velocity) data to representations by a factor of
~20, which improves the speed of frame and SkyCoord initialization. [#7924]
* Refactored ``SkyCoord`` initializer to improve performance and code clarity.
[#7958]
* Sped up initialization of ``Longitude`` by ~40%. [#7616]
> astropy.stats
* The ``SigmaClip`` class and ``sigma_clip`` and
``sigma_clipped_stats`` functions are now significantly faster. [#7478]
* A Cython implementation for `astropy.stats.kuiper_two` and a vectorized
implementation for `astropy.stats.kuiper_false_positive_probability` have
been added, speeding up both functions. [#8104]
> astropy.units
* Sped up creating new composite units, and raising units to some power
[#7549, #7649]
* Sped up Unit.to when target unit is the same as the original unit.
[#7643]
* Lazy-load ``scipy.special`` to shorten ``astropy.units`` import time. [#7636]
> astropy.visualization
* Significantly sped up drawing of contours in WCSAxes. [#7568]
+ Bug Fixes
> astropy.convolution
* Fixed bug in ``convolve_fft`` where masked input was copied with
``numpy.asarray`` instead of ``numpy.asanyarray``.
``numpy.asarray`` removes the mask subclass causing
``numpy.ma.ismasked(input)`` to fail, causing ``convolve_fft``
to ignore all masked input. [#8137]
* Remove function side-effects of input data from ``convolve_fft``.
It was possible for input data to remain modified if particular exceptions
were raised. [#8152]
> astropy.coordinates
* ``EarthLocation.of_address`` now uses the OpenStreetMap geocoding API by
default to retrieve coordinates, with the Google API (which now requires an
API key) as an option. [#7918]
* Fixed a bug that caused frame objects with NaN distances to have NaN sky
positions, even if valid sky coordinates were specified. [#7988]
* Fixed ``represent_as()`` to not round-trip through cartesian if the same
representation class as the instance is passed in. [#7988]
> astropy.io.ascii
* Fixed a problem when ``guess=True`` that ``fast_reader`` options
could be dropped after the first fast reader class was tried. [#5578]
* Units in CDS-formatted tables are now parsed correctly by the units
module. [#7348]
> astropy.io.misc
* Fixed bug when writing a table with masked columns to HDF5. Previously
the mask was being silently dropped. If the ``serialize_meta`` option is
enabled the data mask will now be written as an additional column and the
masked columns will round-trip correctly. [#7481]
* Fixed a bug where writing to HDF5 failed for for tables with columns of
unicode strings. Now those columns are first encoded to UTF-8 and
written as byte strings. [#7024, #8017]
* Fixed a bug with serializing the bounding_box of models initialized
with ``Quantities`` . [#8052]
> astropy.io.fits
* Added support for ``copy.copy`` and ``copy.deepcopy`` for ``HDUList``. [#7218]
* Override ``HDUList.copy()`` to return a shallow HDUList instance. [#7218]
> astropy.modeling
* Fix behaviour of certain models with units, by making certain unit-related
attributes readonly. [#7210]
* Fixed an issue with validating a ``bounding_box`` whose items are
``Quantities``. [#8052]
* Fix ``Moffat1D`` and ``Moffat2D`` derivatives. [#8108]
> astropy.nddata
* Fixed rounding behavior in ``overlap_slices`` for even-sized small
arrays. [#7859]
* Added support for pickling ``NDData`` instances that have an uncertainty.
[#7383]
> astropy.stats
* Fix errors in ``kuiper_false_positive_probability``. [#7975]
> astropy.tests
* Fixing bug that prevented to run the doctests on only a single rst documentation
file rather than all of them. [#8055]
> astropy.time
* Fix a bug when setting a ``TimeDelta`` array item with plain float value(s).
This was always interpreted as a JD (day) value regardless of the
``TimeDelta`` format. [#7990]
> astropy.units
* To simplify fast creation of ``Quantity`` instances from arrays, one can now
write ``array << unit`` (equivalent to ``Quantity(array, unit, copy=False)``).
If ``array`` is already a ``Quantity``, this will convert the quantity to the
requested units; in-place conversion can be done with ``quantity <<= unit``.
[#7734]
> astropy.utils
* Fixed a bug due to which ``report_diff_values()`` was reporting incorrect
number of differences when comparing two ``numpy.ndarray``. [#7470]
* The download progress bar is now only displayed in terminals, to avoid
polluting piped output. [#7577]
* Ignore URL mirror caching when there is no internet. [#8163]
> astropy.visualization
* Right ascension coordinates are now shown in hours by default, and the
``set_format_unit`` method on ``CoordinateHelper`` now works correctly
with angle coordinates. [#7215]
+ Other Changes and Additions
* The documentation build now uses the Sphinx configuration from sphinx-astropy
rather than from astropy-helpers. [#7139]
* Versions of Numpy <1.13 are no longer supported. [#7058]
* Running tests now suppresses the output of the installation stage by default,
to allow easier viewing of the test results. To re-enable the output as
before, use ``python setup.py test --verbose-install``. [#7512]
* The ERFA functions are now wrapped in ufuncs instead of custom C code,
leading to some speed improvements, and setting the stage for allowing
overrides with ``__array_ufunc__``. [#7502]
* Updated the bundled CFITSIO library to 3.450. See
``cextern/cfitsio/docs/changes.txt`` for additional information. [#8014]
* The ``representation`` keywords in coordinate frames are now deprecated in
favor of the ``representation_type`` keywords (which are less
ambiguously named). [#8119]
- Update to 3.0.5
* Update to 3.* is a large step, which contains these main
improvements:
- Full support for velocities in astropy.coordinates
- Support for position updates based on source motion for
SkyCoord objects
- Context managers for versioned constants
- Support for quantities in scipy special functions
- showtable command line script
- Lossless writing and reading mixin columns to HDF5 and
FITS
- Support for FITS time standard
- FITS table performance enhancements
- False alarm probabilities in astropy.stats.LombScargle
- Reading large ASCII files in chunks
- Astropy now only supports Python 3
- pytest plugins moved to external packages

+ New Features
|
|
|
|
|
|
> astropy.convolution
|
|
|
|
|
|
* ``convolve`` now accepts any array-like input, not just ``numpy.ndarray`` or
|
|
|
|
|
|
lists. [#7303]
|
|
|
|
|
|
* ``convolve`` Now raises AstropyUserWarning if nan_treatment='interpolate' and
|
|
|
|
|
|
preserve_nan=False and NaN values are present post convolution. [#8088]
|
|
|
|
|
|
> astropy.coordinates
|
|
|
|
|
|
* The ``SkyCoord.from_name`` constructor now has the ability to create
|
|
|
|
|
|
coordinate objects by parsing object catalogue names that have embedded
|
|
|
|
|
|
J-coordinates. [#7830]
|
|
|
|
|
|
* The new function ``make_transform_graph_docs`` can be used to create a
|
|
|
|
|
|
docstring graph from a custom ``TransformGraph`` object. [#7135]
|
|
|
|
|
|
* ``KDTree`` for catalog matching is now built with sliding midpoint rule
|
|
|
|
|
|
rather than standard. In code, this means setting ``compact_nodes=False``
|
|
|
|
|
|
and ``balanced_tree=False`` in ``cKDTree``. The sliding midpoint rule is much
|
|
|
|
|
|
more suitable for catalog matching, and results in 1000x speedup in some
|
|
|
|
|
|
cases. [#7324]
|
|
|
|
|
|
* Additional information about a site loaded from the Astropy sites registry is
|
|
|
|
|
|
now available in ``EarthLocation.info.meta``. [#7857]
|
|
|
|
|
|
* Added a ``concatenate_representations`` function to combine coordinate
|
|
|
|
|
|
representation data and any associated differentials. [#7922]
|
|
|
|
|
|
* ``BaseCoordinateFrame`` will now check for a method named
|
|
|
|
|
|
``_astropy_repr_in_frame`` when constructing the string forms of attributes.
|
|
|
|
|
|
Allowing any class to control how ``BaseCoordinateFrame`` represents it when
|
|
|
|
|
|
it is an attribute of a frame. [#7745]
|
|
|
|
|
|
* Some rarely-changed attributes of frame classes are now cached, resulting in
|
|
|
|
|
|
speedups (up to 50% in some cases) when creating new scalar frame or
|
|
|
|
|
|
``SkyCoord`` objects. [#7949, #5952]
|
|
|
|
|
|
* Added a ``directional_offset_by`` method to ``SkyCoord`` that computes a new
|
|
|
|
|
|
coordinate given a coordinate, position angle, and angular separation [#5727]
|
|
|
|
|
|
> astropy.cosmology
|
|
|
|
|
|
* The default cosmology has been changed from ``WMAP9`` to ``Planck15``. [#8123]
|
|
|
|
|
|
* Distance calculations with ``LambaCDM`` with no radiation (T_CMB0=0)
|
|
|
|
|
|
are now 20x faster by using elliptic integrals for non-flat cases. [#7155]
|
|
|
|
|
|
* Distance calculations with ``FlatLambaCDM`` with no radiation (T_CMB0=0)
|
|
|
|
|
|
are now 20x faster by using the hypergeometric function solution
|
|
|
|
|
|
for this special case. [#7087]
|
|
|
|
|
|
* Age calculations with ``FlatLambdaCDM`` with no radiation (Tcmb0=0)
|
|
|
|
|
|
are now 1000x faster by using analytic solutions instead of integrating.
|
|
|
|
|
|
[#7117]
|
|
|
|
|
|
> astropy.io.ascii
|
|
|
|
|
|
* Latex reader now ignores ``\toprule``, ``\midrule``, and ``\bottomrule``
|
|
|
|
|
|
commands. [#7349]
|
|
|
|
|
|
* Added the RST (Restructured-text) table format and the fast version of the
|
|
|
|
|
|
RDB reader to the set of formats that are guessed by default. [#5578]
|
|
|
|
|
|
* The read trace (used primarily for debugging) now includes guess argument
|
|
|
|
|
|
sets that were skipped entirely e.g. for not supporting user-supplied kwargs.
|
|
|
|
|
|
All guesses thus removed from ``filtered_guess_kwargs`` are now listed as
|
|
|
|
|
|
"Disabled" at the beginning of the trace. [#5578]
|
|
|
|
|
|
* Emit a warning when reading an ECSV file without specifying the ``format``
|
|
|
|
|
|
and without PyYAML installed. Previously this silently fell through to
|
|
|
|
|
|
parsing as a basic format file and the file metadata was lost. [#7580]
|
|
|
|
|
|
* Optionally allow writing masked columns to ECSV with the mask explicitly
|
|
|
|
|
|
specified as a separate column instead of marking masked elements with ""
|
|
|
|
|
|
(empty string). This allows handling the case of a masked string column
|
|
|
|
|
|
with "" data rows. [#7481]
|
|
|
|
|
|
> astropy.io.misc
|
|
|
|
|
|
* Added support for saving all representation classes and many coordinate
|
|
|
|
|
|
frames to the asdf format. [#7079]
|
|
|
|
|
|
* Added support for saving models with units to the asdf format. [#7237]
|
|
|
|
|
|
* Added a new ``character_as_bytes`` keyword to the HDF5 Table reading
|
|
|
|
|
|
function to control whether byte string columns in the HDF5 file
|
|
|
|
|
|
are left as bytes or converted to unicode. The default is to read
|
|
|
|
|
|
as bytes (``character_as_bytes=True``). [#7024, #8017]
|
|
|
|
|
|
> astropy.io.fits
|
|
|
|
|
|
* ``HDUList.pop()`` now accepts string and tuple extension name
|
|
|
|
|
|
specifications. [#7236]
|
|
|
|
|
|
* Add an ``ignore_hdus`` keyword to ``FITSDiff`` to allow ignoring HDUs by
|
|
|
|
|
|
NAME when diffing two FITS files [#7538]
|
|
|
|
|
|
* Optionally allow writing masked columns to FITS with the mask explicitly
|
|
|
|
|
|
specified as a separate column instead of using the FITS standard of
|
|
|
|
|
|
certain embedded null values (``NaN`` for float, ``TNULL`` for integers).
|
|
|
|
|
|
This can be used to work around limitations in the FITS standard. [#7481]
|
|
|
|
|
|
* All time coordinates can now be written to and read from FITS binary tables,
|
|
|
|
|
|
including those with vectorized locations. [#7430]
|
|
|
|
|
|
* The ``fitsheader`` command line tool now supports a ``dfits+fitsort`` mode,
|
|
|
|
|
|
and the dotted notation for keywords (e.g. ``ESO.INS.ID``). [#7240]
|
|
|
|
|
|
* Fall back to reading arrays using mode='denywrite' if mode='readonly' fails
|
|
|
|
|
|
when using memory-mapping. This solves cases on some platforms when the
|
|
|
|
|
|
available address space was less than the file size (even when using memory
|
|
|
|
|
|
mapping). [#7926]
|
|
|
|
|
|
> astropy.modeling
|
|
|
|
|
|
* Add a ``Multiply`` model which preserves unit through evaluate, unlike
|
|
|
|
|
|
``Scale`` which is dimensionless. [#7210]
|
|
|
|
|
|
* Add a ``uses_quantity`` property to ``Model`` which allows introspection of if
|
|
|
|
|
|
the ``Model`` can accept ``Quantity`` objects. [#7417]
|
|
|
|
|
|
* Add a ``separability_matrix`` function which returns the correlation matrix
|
|
|
|
|
|
of inputs and outputs. [#7803]
|
|
|
|
|
|
* Fixed compatibility of ``JointFitter`` with the latest version of Numpy. [#7984]
|
|
|
|
|
|
* Add ``prior`` and ``posterior`` constraints to modeling parameters. These are
|
|
|
|
|
|
not used by any current fitters, but are provided to allow user code to
|
|
|
|
|
|
experiment with Bayesian fitters. [#7558]
|
|
|
|
|
|
> astropy.nddata
|
|
|
|
|
|
* ``NDUncertainty`` objects now have a ``quantity`` attribute for simple
|
|
|
|
|
|
conversion to quantities. [#7704]
|
|
|
|
|
|
* Add a ``bitmask`` module that provides functions for manipulating bitmasks
|
|
|
|
|
|
and data quality (DQ) arrays. [#7944]
|
|
|
|
|
|
> astropy.stats
|
|
|
|
|
|
* Add an ``astropy.stats.bls`` module with an implementation of the "box least
|
|
|
|
|
|
squares" periodogram that is commonly used for discovering transiting
|
|
|
|
|
|
exoplanets and eclipsing binaries. [#7391]
|
|
|
|
|
|
> astropy.table
|
|
|
|
|
|
* Added support for full use of ``Time`` mixin column for join, hstack, and
|
|
|
|
|
|
vstack table operations. [#6888]
|
|
|
|
|
|
* Added a new table index engine, ``SCEngine``, based on the Sorted Containers
|
|
|
|
|
|
package. [#7574]
|
|
|
|
|
|
* Add a new keyword argument ``serialize_method`` to ``Table.write`` to
|
|
|
|
|
|
control how ``Time`` and ``MaskedColumn`` columns are written. [#7481]
|
|
|
|
|
|
* Allow mixin columns to be used in table ``group`` and ``unique``
|
|
|
|
|
|
functions. This applies to both the key columns and the other data
|
|
|
|
|
|
columns. [#7712]
|
|
|
|
|
|
* Added support for stacking ``Column``, mixin column (e.g. ``Quantity``,
|
|
|
|
|
|
``Time``) or column-like objects. [#7674]
|
|
|
|
|
|
* Added support for inserting a row into a Table that has ``Time`` or
|
|
|
|
|
|
``TimeDelta`` column(s). [#7897]
|
|
|
|
|
|
> astropy.tests
|
|
|
|
|
|
* Added an option ``--readonly`` to the test command to change the
|
|
|
|
|
|
permissions on the temporary installation location to read-only. [#7598]
|
|
|
|
|
|
> astropy.time
|
|
|
|
|
|
* Allow array-valued ``Time`` object to be modified in place. [#6028]
|
|
|
|
|
|
* Added support for missing values (masking) to the ``Time`` class. [#6028]
|
|
|
|
|
|
* Added supper for a 'local' time scale (for free-running clocks, etc.),
|
|
|
|
|
|
and round-tripping to the corresponding FITS time scale. [#7122]
|
|
|
|
|
|
* Added `datetime.timedelta` format class for ``TimeDelta``. [#7441]
|
|
|
|
|
|
* Added ``strftime`` and ``strptime`` methods to ``Time`` class.
|
|
|
|
|
|
These methods are similar to those in the Python standard library
|
|
|
|
|
|
`time` package and provide flexible input and output formatting. [#7323]
|
|
|
|
|
|
* Added ``datetime64`` format to the ``Time`` class to support working with
|
|
|
|
|
|
``numpy.datetime64`` dtype arrays. [#7361]
|
|
|
|
|
|
* Add fractional second support for ``strftime`` and ``strptime`` methods
|
|
|
|
|
|
of ``Time`` class. [#7705]
|
|
|
|
|
|
* Added an ``insert`` method to allow inserting one or more values into a
|
|
|
|
|
|
``Time`` or ``TimeDelta`` object. [#7897]
|
|
|
|
|
|
* Remove timescale from string version of FITS format time string.
|
|
|
|
|
|
The timescale is not part of the FITS standard and should not be included.
|
|
|
|
|
|
This change may cause some compatibility issues for code that relies on
|
|
|
|
|
|
round-tripping a FITS format string with a timescale. Strings generated
|
|
|
|
|
|
from previous versions of this package are still understood but a
|
|
|
|
|
|
DeprecationWarning will be issued. [#7870]
|
|
|
|
|
|
> astropy.uncertainty
|
|
|
|
|
|
* This sub-package was added as a "preview" (i.e. API unstable), containing
|
|
|
|
|
|
the ``Distribution`` class and associated convenience functions. [#6945]
|
|
|
|
|
|
> astropy.units
|
|
|
|
|
|
* Add complex numbers support for ``Quantity._repr_latex_``. [#7676]
|
|
|
|
|
|
* Add ``thermodynamic_temperature`` equivalency to convert between
|
|
|
|
|
|
Jy/beam and "thermodynamic temperature" for cosmology. [#7054]
|
|
|
|
|
|
* Add millibar unit. [#7863]
|
|
|
|
|
|
* Add maggy and nanomaggy unit, as well as associated ``zero_point_flux``
|
|
|
|
|
|
equivalency. [#7891]
|
|
|
|
|
|
* ``AB`` and ``ST`` are now enabled by default, and have alternate names
|
|
|
|
|
|
``ABflux`` and ``STflux``. [#7891]
|
|
|
|
|
|
* Added ``littleh`` unit and associated ``with_H0`` equivalency. [#7970]
|
|
|
|
|
|
> astropy.visualization
|
|
|
|
|
|
* Added ``imshow_norm`` function, which combines imshow and creation of a
|
|
|
|
|
|
``ImageNormalize`` object. [#7785]
|
|
|
|
|
|
> astropy.visualization.wcsaxes
|
|
|
|
|
|
* Add support for setting ``set_separator(None)`` in WCSAxes to use default
|
|
|
|
|
|
separators. [#7570]
|
|
|
|
|
|
* Added two keyword argument options to ``CoordinateHelper.set_format_unit``:
|
|
|
|
|
|
``decimal`` can be used to specify whether to use decimal formatting for the
|
|
|
|
|
|
labels (by default this is False for degrees and hours and True otherwise),
|
|
|
|
|
|
and ``show_decimal_unit`` can be used to determine whether the units should be
|
|
|
|
|
|
shown for decimal labels. [#7318]
|
|
|
|
|
|
* Added documentation for ``transform=`` and ``coord_meta=``. [#7698]
|
|
|
|
|
|
* Allow ``coord_meta=`` to optionally include ``format_unit=``. [#7848]
|
|
|
|
|
|
* Add support for more rcParams related to the grid, ticks, and labels, and
|
|
|
|
|
|
should work with most built-in Matplotlib styles. [#7961]
|
|
|
|
|
|
* Improved rendering of outward-facing ticks. [#7961]
|
|
|
|
|
|
* Add support for ``tick_params`` (which is a standard Matplotlib
|
|
|
|
|
|
function/method) on both the ``WCSAxes`` class and the individual
|
|
|
|
|
|
``CoordinateHelper`` classes. Note that this is provided for compatibility
|
|
|
|
|
|
with Matplotlib syntax users may be familiar with, but it is not the
|
|
|
|
|
|
preferred way to change settings. Instead, methods such as ``set_ticks``
|
|
|
|
|
|
should be preferred. [#7969]
|
|
|
|
|
|
* Moved the argument ``exclude_overlapping`` from ``set_ticks`` to
|
|
|
|
|
|
``set_ticklabel``. [#7969]
|
|
|
|
|
|
* Added a ``pad=`` argument to ``set_ticklabel`` to provide a way to control
|
|
|
|
|
|
the padding between ticks and tick labels. [#7969]
|
|
|
|
|
|
* Added support for setting the tick direction in ``set_ticks`` using the
|
|
|
|
|
|
``direction=`` keyword argument. [#7969]

|
|
|
|
|
* Map ITRS frames to terrestrial WCS coordinates. This will make it possible to
|
|
|
|
|
|
use WCSAxes to make figures that combine both celestial and terrestrial
|
|
|
|
|
|
features. An example is plotting the coordinates of an astronomical transient
|
|
|
|
|
|
over an all- sky satellite image to illustrate the position relative to the
|
|
|
|
|
|
Earth at the time of the event. The ITRS frame is identified with WCSs that
|
|
|
|
|
|
use the ``TLON-`` and ``TLAT-`` coordinate types. There are several examples
|
|
|
|
|
|
of WCSs where this syntax is used to describe terrestrial coordinate systems:

|
|
|
|
|
and the `WCSTools documentation <http://tdc-www.harvard.edu/software/wcstools/wcstools.multiwcs.html>`_.
|
|
|
|
|
|
[#6990]
|
|
|
|
|
|
* Added the abstract base class for the low-level WCS API described in APE 14
|
|
|
|
|
|
(https://doi.org/10.5281/zenodo.1188875). [#7325]
|
|
|
|
|
|
* Add ``WCS.contains()`` function to check if the WCS footprint contains a given sky coordinate. [#7273]
|
|
|
|
|
|
* Added the abstract base class for the high-level WCS API described in APE 14
|
|
|
|
|
|
(https://doi.org/10.5281/zenodo.1188875). [#7325]
|
|
|
|
|
|
* Added the high-level wrapper class for low-level WCS objects as described in
|
|
|
|
|
|
APE 14 (https://doi.org/10.5281/zenodo.1188875). [#7326]
|
|
|
|
|
|
* Added a new property ``WCS.has_distortion``. [#7326]
|
|
|
|
|
|
* Deprecated ``_naxis1`` and ``_naxis2`` in favor of ``pixel_shape``. [#7973]
|
|
|
|
|
|
* Added compatibility to wcslib version 6. [#8093]

|
+ API Changes
|
|
|
|
|
|
> astropy.convolution
|
|
|
|
|
|
* ``kernel`` can now be a tuple. [#7561]
|
|
|
|
|
|
* Not technically an API changes, however, the docstring indicated that ``boundary=None``
|
|
|
|
|
|
was the default when actually it is ``boundary='fill'``. The docstring has been corrected,
|
|
|
|
|
|
however, someone may interpret this as an API change not realizing that nothing has actually
|
|
|
|
|
|
changed. [#7293]
|
|
|
|
|
|
* ``interpolate_replace_nans()`` can no longer accept the keyword argument
|
|
|
|
|
|
``preserve_nan``. It is explicitly set to ``False``. [#8088]
|
|
|
|
|
|
> astropy.coordinates
|
|
|
|
|
|
* Fixed ``astropy.coordinates.concatenate`` to include velocity data in the
|
|
|
|
|
|
concatenation. [#7922]
|
|
|
|
|
|
* Changed the name of the single argument to ``Frame.realize_frame()`` from the
|
|
|
|
|
|
(incorrect) ``representation_type`` to ``data``. [#7923]
|
|
|
|
|
|
* Negative parallaxes passed to ``Distance()`` now raise an error by default
|
|
|
|
|
|
(``allow_negative=False``), or are converted to NaN values with a warning
|
|
|
|
|
|
(``allow_negative=True``). [#7988]
|
|
|
|
|
|
* Negating a ``SphericalRepresentation`` object now changes the angular
|
|
|
|
|
|
coordinates (by rotating 180º) instead of negating the distance. [#7988]
|
|
|
|
|
|
* Creation of new frames now generally creates copies of frame attributes,
|
|
|
|
|
|
rather than inconsistently either copying or making references. [#8204]
|
|
|
|
|
|
* The frame class method ``is_equivalent_frame`` now checks for equality of
|
|
|
|
|
|
components to determine if a frame is the same when it has frame attributes
|
|
|
|
|
|
that are representations, rather than checking if they are the same
|
|
|
|
|
|
object. [#8218]
|
|
|
|
|
|
> astropy.io.ascii
|
|
|
|
|
|
* If a fast reader is explicitly selected (e.g. ``fast_reader='force'``) and
|
|
|
|
|
|
options which are incompatible with the fast reader are provided
|
|
|
|
|
|
(e.g. ``quotechar='##'``) then now a ``ParameterError`` exception will be
|
|
|
|
|
|
raised. [#5578]
|
|
|
|
|
|
* The fast readers will now raise ``InconsistentTableError`` instead of
|
|
|
|
|
|
``CParserError`` if the number of data and header columns do not match.
|
|
|
|
|
|
[#5578]
|
|
|
|
|
|
* Changed a number of ``ValueError`` exceptions to ``InconsistentTableError``
|
|
|
|
|
|
in places where the exception is related to parsing a table which is
|
|
|
|
|
|
inconsistent with the specified table format. Note that
|
|
|
|
|
|
``InconsistentTableError`` inherits from ``ValueError`` so no user code
|
|
|
|
|
|
changes are required. [#7425]
|
|
|
|
|
|
> astropy.io.fits
|
|
|
|
|
|
* The ``fits.table_to_hdu()`` function will translate any column ``format``
|
|
|
|
|
|
attributes to a TDISPn format string, if possible, and store it as a TDISPn
|
|
|
|
|
|
keyword in the ``HDU`` header. [#7226]
|
|
|
|
|
|
> astropy.modeling
|
|
|
|
|
|
* Change the order of the return values from ``FittingWithOutlierRemoval``,
|
|
|
|
|
|
such that ``fitted_model`` comes first, for consistency with other fitters.
|
|
|
|
|
|
For the second value, return only a boolean outlier ``mask``, instead of the
|
|
|
|
|
|
previous ``MaskedArray`` (which included a copy of the input data that was
|
|
|
|
|
|
both redundant and inadvertently corrupted at masked points). Return a
|
|
|
|
|
|
consistent type for the second value when ``niter=0``. [#7407]
|
|
|
|
|
|
* Set the minimum value for the ``bolometric_flux`` parameter of the
|
|
|
|
|
|
``BlackBody1D`` model to zero. [#7045]
|
|
|
|
|
|
> astropy.nddata
|
|
|
|
|
|
* Add two new uncertainty classes, ``astropy.nddata.VarianceUncertainty`` and
|
|
|
|
|
|
``astropy.nddata.InverseVariance``. [#6971]
|
|
|
|
|
|
> astropy.stats
|
|
|
|
|
|
* String values can now be used for the ``cenfunc`` and ``stdfunc``
|
|
|
|
|
|
keywords in the ``SigmaClip`` class and ``sigma_clip`` and
|
|
|
|
|
|
``sigma_clipped_stats`` functions. [#7478]
|
|
|
|
|
|
* The ``SigmaClip`` class and ``sigma_clip`` and
|
|
|
|
|
|
``sigma_clipped_stats`` functions now have a ``masked`` keyword,
|
|
|
|
|
|
which can be used to return either a masked array (default) or an
|
|
|
|
|
|
ndarray with the min/max values. [#7478]
|
|
|
|
|
|
* The ``iters`` keyword has been renamed (and deprecated) to
|
|
|
|
|
|
``maxiters`` in the ``SigmaClip`` class and ``sigma_clip`` and
|
|
|
|
|
|
``sigma_clipped_stats`` functions. [#7478]
|
|
|
|
|
|
> astropy.table
|
|
|
|
|
|
* ``Table.read()`` on a FITS binary table file will convert any TDISPn header
|
|
|
|
|
|
keywords to a Python formatting string when possible, and store it in the
|
|
|
|
|
|
column ``format`` attribute. [#7226]
|
|
|
|
|
|
* No values provided to stack will now raise ``ValueError`` rather than
|
|
|
|
|
|
``TypeError``. [#7674]
|
|
|
|
|
|
> astropy.tests
|
|
|
|
|
|
* ``from astropy.tests.helper import *`` no longer includes
|
|
|
|
|
|
``quantity_allclose``. However,
|
|
|
|
|
|
``from astropy.tests.helper import quantity_allclose`` would still work.
|
|
|
|
|
|
[#7381]
|
|
|
|
|
|
* ``warnings_to_ignore_by_pyver`` option in
|
|
|
|
|
|
``enable_deprecations_as_exceptions()`` now takes ``None`` as key.
|
|
|
|
|
|
Any deprecation message that is mapped to ``None`` will be ignored
|
|
|
|
|
|
regardless of the Python version. [#7790]
|
|
|
|
|
|
> astropy.time
|
|
|
|
|
|
* Added the ability to use ``local`` as time scale in ``Time`` and
|
|
|
|
|
|
``TimeDelta``. [#6487]
|
|
|
|
|
|
* Comparisons, addition, and subtraction of ``Time`` instances with non-time
|
|
|
|
|
|
instances will now return ``NotImplemented`` rather than raise the
|
|
|
|
|
|
``Time``-specific ``OperandTypeError``. This will generally lead to a
|
|
|
|
|
|
regular ``TypeError``. As a result, ``OperandTypeError`` now only occurs if
|
|
|
|
|
|
the operation is between ``Time`` instances of incompatible type or scale.
|
|
|
|
|
|
[#7584]
|
|
|
|
|
|
> astropy.units
|
|
|
|
|
|
* In ``UnitBase.compose()``, if a sequence (list|tuple) is passed in to
|
|
|
|
|
|
``units``, the default for ``include_prefix_units`` is set to
|
|
|
|
|
|
`True`, so that no units get ignored. [#6957]
|
|
|
|
|
|
* Negative parallaxes are now converted to NaN values when using the
|
|
|
|
|
|
``parallax`` equivalency. [#7988]
|
|
|
|
|
|
> astropy.utils
|
|
|
|
|
|
* ``InheritDocstrings`` now also works on class properties. [#7166]
|
|
|
|
|
|
* ``diff_values()``, ``report_diff_values()``, and ``where_not_allclose()``
|
|
|
|
|
|
utility functions are moved from ``astropy.io.fits.diff``. [#7444]
|
|
|
|
|
|
* ``invalidate_caches()`` has been removed from the
|
|
|
|
|
|
``astropy.utils.compat`` namespace, use it directly from ``importlib``. [#7872]
|
|
|
|
|
|
> astropy.visualization
|
|
|
|
|
|
* In ``ImageNormalize``, the default for ``clip`` is set to ``True``. [#7800]
|
|
|
|
|
|
* Changed ``AsymmetricPercentileInterval`` and ``MinMaxInterval`` to
|
|
|
|
|
|
ignore NaN values in arrays. [#7360]
|
|
|
|
|
|
* Automatically default to using ``grid_type='contours'`` in WCSAxes when using
|
|
|
|
|
|
a custom ``Transform`` object if the transform has no inverse. [#7847]
|
|
|
|
|
|
+ Performance Improvements
|
|
|
|
|
|
* Reduced import time by more cautious use of the standard library. [#7647]
|
|
|
|
|
|
> astropy.convolution
|
|
|
|
|
|
* Major performance overhaul to ``convolve()``. [#7293]
|
|
|
|
|
|
* ``convolve()``: Boundaries ``fill``, ``extend``, and ``wrap`` now use a single
|
|
|
|
|
|
implementation that pads the image with the correct boundary values before convolving.
|
|
|
|
|
|
The runtimes of these three were significantly skewed. They now have
|
|
|
|
|
|
equivalent runtimes that are also faster than before due to performant contiguous
|
|
|
|
|
|
memory access. However, this does increase the memory footprint as an entire
|
|
|
|
|
|
new image array is required plus that needed for the padded region.[#7293]
|
|
|
|
|
|
* ``convolve()``: Core computation ported from Cython to C. Several optimization
|
|
|
|
|
|
techniques have been implemented to achieve performance gains, e.g. compiler
|
|
|
|
|
|
hoisting, and vectorization, etc. Compiler optimization level ``-O2`` required for
|
|
|
|
|
|
hoisting and ``-O3`` for vectorization. [#7293]
|
|
|
|
|
|
* ``convolve()``: ``nan_treatment=‘interpolate’`` was slow to compute irrespective of
|
|
|
|
|
|
whether any NaN values exist within the array. The input array is now
|
|
|
|
|
|
checked for NaN values and interpolation is disabled if non are found. This is a
|
|
|
|
|
|
significant performance boost for arrays without NaN values. [#7293]
|
|
|
|
|
|
> astropy.coordinates
|
|
|
|
|
|
* Sped up creating SkyCoord objects by a factor of ~2 in some cases. [#7615]
|
|
|
|
|
|
* Sped up getting xyz vectors from ``CartesianRepresentation`` (which
|
|
|
|
|
|
is used a lot internally). [#7638]
|
|
|
|
|
|
* Sped up transformations and some representation methods by replacing
|
|
|
|
|
|
python code with (compiled) ``erfa`` ufuncs. [#7639]
|
|
|
|
|
|
* Sped up adding differential (velocity) data to representations by a factor of
|
|
|
|
|
|
~20, which improves the speed of frame and SkyCoord initialization. [#7924]
|
|
|
|
|
|
* Refactored ``SkyCoord`` initializer to improve performance and code clarity.
|
|
|
|
|
|
[#7958]
|
|
|
|
|
|
* Sped up initialization of ``Longitude`` by ~40%. [#7616]
|
|
|
|
|
|
> astropy.stats
|
|
|
|
|
|
* The ``SigmaClip`` class and ``sigma_clip`` and
|
|
|
|
|
|
``sigma_clipped_stats`` functions are now significantly faster. [#7478]
|
|
|
|
|
|
* A Cython implementation for `astropy.stats.kuiper_two` and a vectorized
|
|
|
|
|
|
implementation for `astropy.stats.kuiper_false_positive_probability` have
|
|
|
|
|
|
been added, speeding up both functions. [#8104]
|
|
|
|
|
|
> astropy.units
|
|
|
|
|
|
* Sped up creating new composite units, and raising units to some power
|
|
|
|
|
|
[#7549, #7649]
|
|
|
|
|
|
* Sped up Unit.to when target unit is the same as the original unit.
|
|
|
|
|
|
[#7643]
|
|
|
|
|
|
* Lazy-load ``scipy.special`` to shorten ``astropy.units`` import time. [#7636]
|
|
|
|
|
|
> astropy.visualization
|
|
|
|
|
|
* Significantly sped up drawing of contours in WCSAxes. [#7568]

|
|
|
|
+ Bug Fixes
|
|
|
|
|
|
> astropy.convolution
|
|
|
|
|
|
* Fixed bug in ``convolve_fft`` where masked input was copied with
|
|
|
|
|
|
``numpy.asarray`` instead of ``numpy.asanyarray``.
|
|
|
|
|
|
``numpy.asarray`` removes the mask subclass causing
|
|
|
|
|
|
``numpy.ma.ismasked(input)`` to fail, causing ``convolve_fft``
|
|
|
|
|
|
to ignore all masked input. [#8137]
|
|
|
|
|
|
* Remove function side-effects of input data from ``convolve_fft``.
|
|
|
|
|
|
It was possible for input data to remain modified if particular exceptions
|
|
|
|
|
|
were raised. [#8152]
|
|
|
|
|
|
> astropy.coordinates
|
|
|
|
|
|
* ``EarthLocation.of_address`` now uses the OpenStreetMap geocoding API by
|
|
|
|
|
|
default to retrieve coordinates, with the Google API (which now requires an
|
|
|
|
|
|
API key) as an option. [#7918]
|
|
|
|
|
|
* Fixed a bug that caused frame objects with NaN distances to have NaN sky
|
|
|
|
|
|
positions, even if valid sky coordinates were specified. [#7988]
|
|
|
|
|
|
* Fixed ``represent_as()`` to not round-trip through cartesian if the same
|
|
|
|
|
|
representation class as the instance is passed in. [#7988]
|
|
|
|
|
|
> astropy.io.ascii
|
|
|
|
|
|
* Fixed a problem when ``guess=True`` that ``fast_reader`` options
|
|
|
|
|
|
could be dropped after the first fast reader class was tried. [#5578]
|
|
|
|
|
|
* Units in CDS-formatted tables are now parsed correctly by the units

|
|
module. [#7348]
|
|
|
|
|
|
> astropy.io.misc
|
|
|
|
|
|
* Fixed bug when writing a table with masked columns to HDF5. Previously
|
|
|
|
|
|
the mask was being silently dropped. If the ``serialize_meta`` option is
|
|
|
|
|
|
enabled the data mask will now be written as an additional column and the
|
|
|
|
|
|
masked columns will round-trip correctly. [#7481]
|
|
|
|
|
|
* Fixed a bug where writing to HDF5 failed for for tables with columns of
|
|
|
|
|
|
unicode strings. Now those columns are first encoded to UTF-8 and
|
|
|
|
|
|
written as byte strings. [#7024, #8017]
|
|
|
|
|
|
* Fixed a bug with serializing the bounding_box of models initialized

|
with ``Quantities`` . [#8052]
|
|
|
|
|
|
> astropy.io.fits
|
|
|

* Fix ``Moffat1D`` and ``Moffat2D`` derivatives. [#8108]
|
|
|
|
|
|
> astropy.nddata
|
|
|
|
|
|
* Fixed rounding behavior in ``overlap_slices`` for even-sized small
|
|
|
|
|
|
arrays. [#7859]
|
|
|
|
|
|
* Added support for pickling ``NDData`` instances that have an uncertainty.
|
|
|
|
|
|
[#7383]
|
|
|
|
|
|
> astropy.stats
|
|
|
|
|
|
* Fix errors in ``kuiper_false_positive_probability``. [#7975]
|
|
|
|
|
|
> astropy.tests
|
|
|
|
|
|
* Fixing bug that prevented to run the doctests on only a single rst documentation
|
|
|
|
|
|
file rather than all of them. [#8055]
|
|
|
|
|
|
> astropy.time
|
|
|
|
|
|
* Fix a bug when setting a ``TimeDelta`` array item with plain float value(s).
|
|
|
|
|
|
This was always interpreted as a JD (day) value regardless of the
|
|
|
|
|
|
``TimeDelta`` format. [#7990]
|
|
|
|
|
|
> astropy.units
|
|
|
|
|
|
* To simplify fast creation of ``Quantity`` instances from arrays, one can now
|
|
|
|
|
|
write ``array << unit`` (equivalent to ``Quantity(array, unit, copy=False)``).
|
|
|
|
|
|
If ``array`` is already a ``Quantity``, this will convert the quantity to the
|
|
|
|
|
|
requested units; in-place conversion can be done with ``quantity <<= unit``.
|
|
|
|
|
|
[#7734]
|
|
|
|
|
|
> astropy.utils
|
|
|
|
|
|
* Fixed a bug due to which ``report_diff_values()`` was reporting incorrect
|
|
|
|
|
|
number of differences when comparing two ``numpy.ndarray``. [#7470]
|
|
|
|
|
|
* The download progress bar is now only displayed in terminals, to avoid
|
|
|
|
|
|
polluting piped output. [#7577]
|
|
|
|
|
|
* Ignore URL mirror caching when there is no internet. [#8163]
|
|
|
|
|
|
> astropy.visualization
|
|
|
|
|
|
* Right ascension coordinates are now shown in hours by default, and the
|
|
|
|
|
|
``set_format_unit`` method on ``CoordinateHelper`` now works correctly
|
|
|
|
|
|
with angle coordinates. [#7215]
|
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
|
* The documentation build now uses the Sphinx configuration from sphinx-astropy
|
|
|
|
|
|
rather than from astropy-helpers. [#7139]
|
|
|
|
|
|
* Versions of Numpy <1.13 are no longer supported. [#7058]
|
|
|
|
|
|
* Running tests now suppresses the output of the installation stage by default,
|
|
|
|
|
|
to allow easier viewing of the test results. To re-enable the output as
|
|
|
|
|
|
before, use ``python setup.py test --verbose-install``. [#7512]
|
|
|
|
|
|
* The ERFA functions are now wrapped in ufuncs instead of custom C code,
|
|
|
|
|
|
leading to some speed improvements, and setting the stage for allowing
|
|
|
|
|
|
overrides with ``__array_ufunc__``. [#7502]
|
|
|
|
|
|
* Updated the bundled CFITSIO library to 3.450. See
|
|
|
|
|
|
``cextern/cfitsio/docs/changes.txt`` for additional information. [#8014]
|
|
|
|
|
|
* The ``representation`` keywords in coordinate frames are now deprecated in
|
|
|
|
|
|
favor of the ``representation_type`` keywords (which are less
|
|
|
|
|
|
ambiguously named). [#8119]

Fri Jan 5 09:01:00 UTC 2018 - alarrosa@suse.com
|
|
|
|
|
|
|
|
|
|
|
|
- Update to astropy 2.0.3
|
|
|
|
|
|
* Bugfixes:
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
- Ecliptic frame classes now support attributes v_x, v_y, v_z when using
|
|
|
|
|
|
with a Cartesian representation.
|
|
|
|
|
|
- Added a nicer error message when accidentally calling
|
|
|
|
|
|
frame.representation instead of frame.data in the context of methods
|
|
|
|
|
|
that use ._apply().
|
|
|
|
|
|
- Creating a new SkyCoord from a list of multiple SkyCoord objects now
|
|
|
|
|
|
yield the correct type of frame, and works at all for non-equatorial
|
|
|
|
|
|
frames.
|
|
|
|
|
|
- Improved accuracy of velocity calculation in
|
|
|
|
|
|
EarthLocation.get_gcrs_posvel.
|
|
|
|
|
|
- Improved accuracy of radial velocity corrections in
|
|
|
|
|
|
SkyCoord.radial_velocity_correction`.
|
|
|
|
|
|
- The precision of ecliptic frames is now much better, after removing the
|
|
|
|
|
|
nutation from the rotation and fixing the computation of the position
|
|
|
|
|
|
of the Sun.
|
|
|
|
|
|
* astropy.extern
|
|
|
|
|
|
- Version 0.2.1 of pytest-astropy is included as an external package.
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
- Fix writing the result of fitsdiff to file with --output-file.
|
|
|
|
|
|
- Fix a minor bug where FITS_rec instances can not be indexed with tuples
|
|
|
|
|
|
and other sequences that end up with a scalar.
|
|
|
|
|
|
* astropy.io.misc
|
|
|
|
|
|
- Fix ImportError when hdf5 is imported first in a fresh Python
|
|
|
|
|
|
interpreter in Python 3.
|
|
|
|
|
|
* astropy.nddata
|
|
|
|
|
|
- Suppress errors during WCS creation in CCDData.read().
|
|
|
|
|
|
- Fixed a problem with CCDData.read when the extension wasn't given and
|
|
|
|
|
|
the primary HDU contained no data but another HDU did. In that case the
|
|
|
|
|
|
header were not correctly combined.
|
|
|
|
|
|
* astropy.stats
|
|
|
|
|
|
- Fixed an issue where the biweight statistics functions would sometimes
|
|
|
|
|
|
cause runtime underflow/overflow errors for float32 input arrays.
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
- Fixed a problem when printing a table when a column is deleted and
|
|
|
|
|
|
garbage-collected, and the format function caching mechanism happens to
|
|
|
|
|
|
re-use the same cache key.
|
|
|
|
|
|
- Fixed a problem when comparing a unicode masked column (on left side)
|
|
|
|
|
|
to a bytes masked column (on right side).
|
|
|
|
|
|
- Fixed a problem in comparing masked columns in bytes and unicode when
|
|
|
|
|
|
the unicode had masked entries.
|
|
|
|
|
|
* astropy.tests
|
|
|
|
|
|
- Fixed a bug that causes tests for rst files to not be run on certain
|
|
|
|
|
|
platforms.
|
|
|
|
|
|
- Fixed a bug that caused the doctestplus plugin to not work nicely with
|
|
|
|
|
|
the hypothesis package.
|
|
|
|
|
|
- Fixed a bug that meant that the data.astropy.org mirror could not be
|
|
|
|
|
|
used when using --remote-data=astropy.
|
|
|
|
|
|
- Support compatibility with new pytest-astropy plugins.
|
|
|
|
|
|
- When testing, astropy (or the package being tested) is now installed to
|
|
|
|
|
|
a temporary directory instead of copying the build. This allows entry
|
|
|
|
|
|
points to work correctly.
|
|
|
|
|
|
* astropy.time
|
|
|
|
|
|
- Initialization of Time instances now is consistent for all formats to
|
|
|
|
|
|
ensure that -0.5 <= jd2 < 0.5.
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
- Ensure that Quantity slices can be set with objects that have a unit
|
|
|
|
|
|
attribute (such as Column).
|
|
|
|
|
|
* astropy.utils
|
|
|
|
|
|
- download_files_in_parallel now respects the given timeout value.
|
|
|
|
|
|
- Fixed bugs in remote data handling and also in IERS unit test related
|
|
|
|
|
|
to path URL, and URI normalization on Windows.
|
|
|
|
|
|
- Fixed a bug that caused get_pkg_data_fileobj to not work correctly when
|
|
|
|
|
|
used with non-local data from inside packages.
|
|
|
|
|
|
- Make sure get_pkg_data_fileobj fails if the URL can not be read, and
|
|
|
|
|
|
correctly falls back on the mirror if necessary.
|
|
|
|
|
|
- Fix the finddiff option in find_current_module to properly deal with
|
|
|
|
|
|
submodules.
|
|
|
|
|
|
- Fixed pyreadline import in utils.console.isatty for older IPython
|
|
|
|
|
|
versions on Windows.
|
|
|
|
|
|
* astropy.visualization
|
|
|
|
|
|
- Fixed the vertical orientation of the fits2bitmap output bitmap image
|
|
|
|
|
|
to match that of the FITS image.
|
|
|
|
|
|
- Added a workaround for a bug in matplotlib so that the fits2bitmap
|
|
|
|
|
|
script generates the correct output file type.
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
* No longer require LaTeX to build the documentation locally and use
|
|
|
|
|
|
mathjax instead.
|
|
|
|
|
|
* Fixed broken links in the documentation.
|
|
|
|
|
|
* Ensured that all tests use the Astropy data mirror if needed.

- The latest astropy version requires liberfa 1.3.0 even if
|
|
|
|
|
|
it builds fine with 1.2.0 since it requires the eraEceq06 symbol.

- update to version 1.1.1
|
|
|
|
|
|
+ New Features
|
|
|
|
|
|
- ``astropy.io.registry``
|
|
|
|
|
|
* Allow ``pathlib.Path`` objects (available in Python 3.4 and later) for
|
|
|
|
|
|
specifying the file name in registry read / write functions. [#4405]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
* ``console.human_file_size`` now accepts quantities with byte-equivalent
|
|
|
|
|
|
units [#4373]
|
|
|
|
|
|
+ Bug Fixes
|
|
|
|
|
|
- ``astropy.analytic_functions``
|
|
|
|
|
|
* Fixed the blackbody functions' handling of overflows on some platforms
|
|
|
|
|
|
(Windows with MSVC, older Linux versions) with a buggy ``expm1`` function.
|
|
|
|
|
|
[#4393]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
* Fixed an bug where updates to string columns in FITS tables were not saved
|
|
|
|
|
|
on Python 3. [#4452]
|
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
|
- Updated bundled astropy-helpers to v1.1.1. [#4413]
|
|
|
|
|
|
- update to version 1.1
|
|
|
|
|
|
+ New Features
|
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
|
- Added new tools ``set_temp_config`` and ``set_temp_cache`` which can be
|
|
|
|
|
|
used either as function decorators or context managers to temporarily
|
|
|
|
|
|
use alternative directories in which to read/write the Astropy config
|
|
|
|
|
|
files and download caches respectively. This is especially useful for
|
|
|
|
|
|
testing, though ``set_temp_cache`` may also be used as a way to provide
|
|
|
|
|
|
an alternative (application specific) download cache for large data files,
|
|
|
|
|
|
rather than relying on the default cache location in users' home
|
|
|
|
|
|
directories. [#3975]
|
|
|
|
|
|
- ``astropy.constants``

- Added Moffat2DKernel. [#3965]
|
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
|
- Added ``get_constellation`` function and ``SkyCoord.get_constellation``
|
|
|
|
|
|
convenience method to determine the constellation that a coordinate
|
|
|
|
|
|
is in. [#3758]
|
|
|
|
|
|
- Added ``PrecessedGeocentric`` frame, which is based on GCRS, but precessed
|
|
|
|
|
|
to a specific requested mean equinox. [#3758]
|
|
|
|
|
|
- Added ``Supergalactic`` frame to support de Vaucouleurs supergalactic
|
|
|
|
|
|
coordinates. [#3892]
|
|
|
|
|
|
- ``SphericalRepresentation`` now has a ``._unit_representation`` class attribute to specify
|
|
|
|
|
|
an equivalent UnitSphericalRepresentation. This allows subclasses of
|
|
|
|
|
|
representations to pair up correctly. [#3757]
|
|
|
|
|
|
- Added functionality to support getting the locations of observatories by
|
|
|
|
|
|
name. See ``astropy.coordinates.EarthLocation.of_site``. [#4042]
|
|
|
|
|
|
- Added ecliptic coordinates, including ``GeocentricTrueEcliptic``,
|
|
|
|
|
|
``BarycentricTrueEcliptic``, and ``HeliocentricTrueEcliptic``. [#3749]
|
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
|
- Add Planck 2015 cosmology [#3476]
|
|
|
|
|
|
- Distance calculations now > 20-40x faster for the supplied
|
|
|
|
|
|
cosmologies due to implementing Cython scalar versions of
|
|
|
|
|
|
``FLRW.inv_efunc``.[#4127]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- Automatically use ``guess=False`` when reading if the file ``format`` is
|
|
|
|
|
|
provided and the format parameters are uniquely specified. This update
|
|
|
|
|
|
also removes duplicate format guesses to improve performance. [#3418]
|
|
|
|
|
|
- Calls to ascii.read() for fixed-width tables may now omit one of the keyword
|
|
|
|
|
|
arguments ``col_starts`` or ``col_ends``. Columns will be assumed to begin and
|
|
|
|
|
|
end immediately adjacent to each other. [#3657]
|
|
|
|
|
|
- Add a function ``get_read_trace()`` that returns a traceback of the
|
|
|
|
|
|
attempted read formats for the last call to ``astropy.io.ascii.read``. [#3688]
|
|
|
|
|
|
- Supports LZMA decompression via ``get_readable_fileobj`` [#3667]
|
|
|
|
|
|
- Allow ``-`` character is Sextractor format column names. [#4168]
|
|
|
|
|
|
- Improve DAOphot reader to read multi-aperture files [#3535, #4207]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- Support reading and writing from bzip2 compressed files. i.e. ``.fits.bz2``
|
|
|
|
|
|
files. [#3789]
|
|
|
|
|
|
- Included a new command-line script called ``fitsinfo`` to display
|
|
|
|
|
|
a summary of the HDUs in one or more FITS files. [#3677]
|
|
|
|
|
|
- ``astropy.io.misc``
|
|
|
|
|
|
- Support saving all meta information, description and units of tables and columns
|
|
|
|
|
|
in HDF5 files [#4103]
|
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
|
- A new method was added to ``astropy.io.votable.VOTable``,
|
|
|
|
|
|
``get_info_by_id`` to conveniently find an ``INFO`` element by its
|
|
|
|
|
|
``ID`` attribute. [#3633]
|
|
|
|
|
|
- Instances in the votable tree now have better ``__repr__``
|
|
|
|
|
|
methods. [#3639]
|
|
|
|
|
|
- ``astropy.logger.py``
|
|
|
|
|
|
- Added log levels (e.g., DEBUG, INFO, CRITICAL) to ``astropy.log`` [#3947]
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- Added a new ``Parameter.validator`` interface for setting a validation
|
|
|
|
|
|
method on individual model parameters. See the ``Parameter``
|
|
|
|
|
|
documentation for more details. [#3910]
|
|
|
|
|
|
- The projection classes that are named based on the 3-letter FITS
|
|
|
|
|
|
WCS projections (e.g. ``Pix2Sky_TAN``) now have aliases using
|
|
|
|
|
|
longer, more descriptive names (e.g. ``Pix2Sky_Gnomonic``).
|
|
|
|
|
|
[#3583]
|
|
|
|
|
|
- All of the standard FITS WCS projection types have been
|
|
|
|
|
|
implemented in ``astropy.modeling.projections`` (by wrapping
|
|
|
|
|
|
WCSLIB). [#3906]
|
|
|
|
|
|
- Added ``Sersic1D`` and ``Sersic2D`` model classes. [#3889]
|
|
|
|
|
|
- Added the Voigt profile to existing models. [#3901]
|
|
|
|
|
|
- Added ``bounding_box`` property and ``render_model`` function [#3909]
|
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
|
- Added ``block_reduce`` and ``block_replicate`` functions. [#3453]
|
|
|
|
|
|
- ``extract_array`` now offers different options to deal with array
|
|
|
|
|
|
boundaries [#3727]
|
|
|
|
|
|
- Added a new ``Cutout2D`` class to create postage stamp image cutouts
|
|
|
|
|
|
with optional WCS propagation. [#3823]
|
|
|
|
|
|
- ``astropy.stats``
|
|
|
|
|
|
- Added ``sigma_lower`` and ``sigma_upper`` keywords to
|
|
|
|
|
|
``sigma_clip`` to allow for unsymmetric clipping. [#3595]
|
|
|
|
|
|
- Added ``cenfunc``, ``stdfunc``, and ``axis`` keywords to
|
|
|
|
|
|
``sigma_clipped_stats``. [#3792]
|
|
|
|
|
|
- ``sigma_clip`` automatically masks invalid input values (NaNs, Infs) before
|
|
|
|
|
|
performing the clipping [#4051]
|
|
|
|
|
|
- Added the ``histogram`` routine, which is similar to ``np.histogram`` but
|
|
|
|
|
|
includes several additional options for automatic determination of optimal
|
|
|
|
|
|
histogram bins. Associated helper routines include ``bayesian_blocks``,
|
|
|
|
|
|
``friedman_bin_width``, ``scott_bin_width``, and ``knuth_bin_width``.
|
|
|
|
|
|
This functionality was ported from the astroML_ library. [#3756]
|
|
|
|
|
|
- Added the ``bayesian_blocks`` routine, which implements a dynamic algorithm
|
|
|
|
|
|
for locating change-points in various time series. [#3756]
|
|
|
|
|
|
- A new function ``poisson_conf_interval()`` was added to allow easy calculation
|
|
|
|
|
|
of several standard formulae for the error bars on the mean of a Poisson variable
|
|
|
|
|
|
estimated from a single sample.
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- ``add_column()`` and ``add_columns()`` now have ``rename_duplicate``
|
|
|
|
|
|
option to rename new column(s) rather than raise exception when its name
|
|
|
|
|
|
already exists. [#3592]
|
|
|
|
|
|
- Added ``Table.to_pandas`` and ``Table.from_pandas`` for converting to/from
|
|
|
|
|
|
pandas dataframes. [#3504]
|
|
|
|
|
|
- Initializing a ``Table`` with ``Column`` objects no longer requires
|
|
|
|
|
|
that the column ``name`` attribute be defined. [#3781]
|
|
|
|
|
|
- Added an ``info`` property to ``Table`` objects which provides configurable
|
|
|
|
|
|
summary information about the table and its columns. [#3731]
|
|
|
|
|
|
- Added an ``info`` property to column classes (``Column`` or mixins). This
|
|
|
|
|
|
serves a dual function of providing configurable summary information about
|
|
|
|
|
|
the column, and acting as a manager of column attributes such as
|
|
|
|
|
|
name, format, or description. [#3731]
|
|
|
|
|
|
- Updated table and column representation to use the ``dtype_info_name``
|
|
|
|
|
|
function for the dtype value. Removed the default "masked=False"
|
|
|
|
|
|
from the table representation. [#3868, #3869]
|
|
|
|
|
|
- Updated row representation to be consistent with the corresponding
|
|
|
|
|
|
table representation for that row. Added HTML representation so a
|
|
|
|
|
|
row displays nicely in IPython notebook.
|
|
|
|
|
|
- Added a new table indexing engine allowing for the creation of
|
|
|
|
|
|
indices on one or more columns of a table using ``add_index``. These
|
|
|
|
|
|
indices enable new functionality such as searching for rows by value
|
|
|
|
|
|
using ``loc`` and ``iloc``, as well as increased performance for
|
|
|
|
|
|
certain operations. [#3915]
|
|
|
|
|
|
- Added capability to include a structured array or recarray in a table
|
|
|
|
|
|
as a mixin column. This allows for an approximation of nested tables.
|
|
|
|
|
|
[#3925]
|
|
|
|
|
|
- Added ``keep_byteorder`` option to ``Table.as_array()``. See the
|
|
|
|
|
|
"API Changes" section below. [#4080]
|
|
|
|
|
|
- Added a new method ``Table.replace_column()`` to replace an existing
|
|
|
|
|
|
column with a new data column. [#4090]
|
|
|
|
|
|
- Added a ``tableclass`` option to ``Table.pformat()`` to allow specifying
|
|
|
|
|
|
a list of CSS classes added to the HTML table. [#4131]
|
|
|
|
|
|
- New CSS for jsviewer table [#2917, #2982, #4174]
|
|
|
|
|
|
- Added a new ``Table.show_in_notebook`` method that shows an interactive view
|
|
|
|
|
|
of a Table (similar to ``Table.show_in_browser(jsviewer=True)``) in an
|
|
|
|
|
|
Python/Jupyter notebook. [#4197]
|
|
|
|
|
|
- ``astropy.tests``
|
|
|
|
|
|
- Added new test config options, ``config_dir`` and ``cache_dir`` (these
|
|
|
|
|
|
can be edited in ``setup.cfg`` or as extra command-line options to
|
|
|
|
|
|
py.test) for setting the locations to use for the Astropy config files
|
|
|
|
|
|
and download caches (see also the related ``set_temp_config/cache``
|
|
|
|
|
|
features added in ``astropy.config``). [#3975]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- Add support for FITS standard time strings. [#3547]
|
|
|
|
|
|
- Allow the ``format`` attribute to be updated in place to change the
|
|
|
|
|
|
default representation of a ``Time`` object. [#3673]
|
|
|
|
|
|
- Add support for shape manipulation (reshape, ravel, etc.). [#3224]
|
|
|
|
|
|
- Add argmin, argmax, argsort, min, max, ptp, sort methods. [#3581]
|
|
|
|
|
|
- Add ``Time.to_datetime`` method for converting ``Time`` objects to
|
|
|
|
|
|
timezone-aware datetimes. [#4119]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- Added furlong to imperial units. [#3529]
|
|
|
|
|
|
- Added mil to imperial units. [#3716]
|
|
|
|
|
|
- Added stone to imperial units. [#4192]
|
|
|
|
|
|
- Added Earth Mass (``M_earth``) and Jupiter mass (``M_jup``) to units [#3907]
|
|
|
|
|
|
- Added support for functional units, in particular the logarithmic ones
|
|
|
|
|
|
``Magnitude``, ``Decibel``, and ``Dex``. [#1894]
|
|
|
|
|
|
- Quantities now work with the unit support in matplotlib. See
|
|
|
|
|
|
:ref:`plotting-quantities`. [#3981]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- Added new ``OrderedDescriptor`` and ``OrderedDescriptorContainer`` utility
|
|
|
|
|
|
classes that make it easier to implement classes with declarative APIs,
|
|
|
|
|
|
wherein class-level attributes have an inherit "ordering" to them that is
|
|
|
|
|
|
specified by the order in which those attributes are defined in the class
|
|
|
|
|
|
declaration (by defining them using special descriptors that have
|
|
|
|
|
|
``OrderedDescriptor`` as a base class). See the API documentation for
|
|
|
|
|
|
these classes for more details. Coordinate frames and models now use this
|
|
|
|
|
|
interface. [#3679]
|
|
|
|
|
|
- The ``get_pkg_data_*`` functions now take an optional ``package`` argument
|
|
|
|
|
|
which allows specifying any package to read package data filenames or
|
|
|
|
|
|
content out of, as opposed to only being able to use data from the package
|
|
|
|
|
|
that the function is called from. [#4079]
|
|
|
|
|
|
- Added function ``dtype_info_name`` to the ``data_info`` module to provide
|
|
|
|
|
|
the name of a ``dtype`` for human-readable informational purposes. [#3868]
|
|
|
|
|
|
- Added ``classproperty`` decorator--this is to ``property`` as
|
|
|
|
|
|
``classmethod`` is to normal instance methods. [#3982]
|
|
|
|
|
|
- ``iers.open`` now handles network URLs, as well as local paths. [#3850]
|
|
|
|
|
|
- The ``astropy.utils.wraps`` decorator now takes an optional
|
|
|
|
|
|
``exclude_args`` argument not shared by the standard library ``wraps``
|
|
|
|
|
|
decorator (as it is unique to the Astropy version's ability of copying
|
|
|
|
|
|
the wrapped function's argument signature). ``exclude_args`` allows
|
|
|
|
|
|
certain arguments on the wrapped function to be excluded from the signature
|
|
|
|
|
|
of the wrapper function. This is particularly useful when wrapping an
|
|
|
|
|
|
instance method as a function (to exclude the ``self`` argument). [#4017]
|
|
|
|
|
|
- ``get_readable_fileobj`` can automatically decompress LZMA ('.xz')
|
|
|
|
|
|
files using the ``lzma`` module of Python 3.3+ or, when available, the
|
|
|
|
|
|
``backports.lzma`` package on earlier versions. [#3667]
|
|
|
|
|
|
- The ``resolve_name`` utility now accepts any number of additional
|
|
|
|
|
|
positional arguments that are automatically dotted together with the
|
|
|
|
|
|
first ``name`` argument. [#4083]
|
|
|
|
|
|
- Added ``is_url_in_cache`` for resolving paths to cached files via URLS
|
|
|
|
|
|
and checking if files exist. [#4095]
|
|
|
|
|
|
- Added a ``step`` argument to the ``ProgressBar.map`` method to give
|
|
|
|
|
|
users control over the update frequency of the progress bar. [#4191]
|
|
|
|
|
|
- ``astropy.visualization``
|
|
|
|
|
|
- Added a function / context manager ``quantity_support`` for enabling
|
|
|
|
|
|
seamless ploting of ``Quantity`` instances in matplotlib. [#3981]
|
|
|
|
|
|
- Added the ``hist`` function, which is similar to ``plt.hist`` but
|
|
|
|
|
|
includes several additional options for automatic determination of optimal
|
|
|
|
|
|
histogram bins. This functionality was ported from the astroML_ library.
|
|
|
|
|
|
[#3756]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- The included version of wcslib has been upgraded to 5.10. [#4239]
|
|
|
|
|
|
The minimum required version of wcslib in the 4.x series remains 4.24.
|
|
|
|
|
|
The minimum required version of wcslib in the 5.x series is
|
|
|
|
|
|
5.8. Building astropy against a wcslib 5.x prior to 5.8
|
|
|
|
|
|
will raise an ``ImportError`` when ``astropy.wcs`` is imported.
|
|
|
|
|
|
The wcslib changes relevant to astropy are:
|
|
|
|
|
|
- The FITS headers returned by ``astropy.wcs.WCS.to_header`` and
|
|
|
|
|
|
``astropy.wcs.WCS.to_header_string`` now include values with
|
|
|
|
|
|
more precision. This will result in numerical differences in
|
|
|
|
|
|
your results if you convert ``astropy.wcs.WCS`` objects to FITS
|
|
|
|
|
|
headers and use the results.
|
|
|
|
|
|
- ``astropy.wcs.WCS`` now recognises the ``TPV``, ``TPD``,
|
|
|
|
|
|
``TPU``, ``DSS``, ``TNX`` and ``ZPX`` polynomial distortions.
|
|
|
|
|
|
- Added relaxation flags to allow ``PC0i_0ja``, ``PV0j_0ma``, and
|
|
|
|
|
|
``PS0j_0ma`` (i.e. with leading zeroes on the index).
|
|
|
|
|
|
- Tidied up error reporting, particularly relating to translating
|
|
|
|
|
|
status returns from lower-level functions.
|
|
|
|
|
|
- Changed output formatting of floating point values in
|
|
|
|
|
|
``to_header``.
|
|
|
|
|
|
- Enhanced text representation of ``WCS`` objects. [#3604]
|
|
|
|
|
|
- The ``astropy.tests.helper`` module is now part of the public API (and has a
|
|
|
|
|
|
documentation page). This module was in previous releases of astropy,
|
|
|
|
|
|
but was not considered part of the public API until now. [#3890]
|
|
|
|
|
|
- There is a new function ``astropy.online_help`` to search the
|
|
|
|
|
|
astropy documentation and display the result in a web
|
|
|
|
|
|
browser. [#3642]
|
|
|
|
|
|
+ API changes
|
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
|
- ``FLRW._tfunc`` and ``FLRW._xfunc`` are marked as deprecated. Users
|
|
|
|
|
|
should use the new public interfaces ``FLRW.lookback_time_integrand``
|
|
|
|
|
|
and ``FLRW.abs_distance_integrand`` instead. [#3767]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- The default header line processing was made to be consistent with data line
|
|
|
|
|
|
processing in that it now ignores blank lines that may have whitespace
|
|
|
|
|
|
characters. Any code that explicitly specifies a ``header_start`` value
|
|
|
|
|
|
for parsing a file with blank lines in the header containing whitespace will
|
|
|
|
|
|
need to be updated. [#2654]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- The ``uint`` argument to ``fits.open`` is now True by default; that is,
|
|
|
|
|
|
arrays using the FITS unsigned integer convention will be detected, and
|
|
|
|
|
|
read as unsigned integers by default. A new config option for
|
|
|
|
|
|
``io.fits``, ``enable_uint``, can be changed to False to revert to the
|
|
|
|
|
|
original behavior of ignoring the ``uint`` convention unless it is
|
|
|
|
|
|
explicitly requested with ``uint=True``. [#3916]
|
|
|
|
|
|
- The ``ImageHDU.NumCode`` and ``ImageHDU.ImgCode`` attributes (and same
|
|
|
|
|
|
for other classes derived from ``_ImageBaseHDU``) are deprecated. Instead,
|
|
|
|
|
|
the ``astropy.io.fits`` module-level constants ``BITPIX2DTYPE`` and
|
|
|
|
|
|
``DTYPE2BITPIX`` can be used. [#3916]
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- Note: Comparisons of model parameters with array-like values now
|
|
|
|
|
|
yields a Numpy boolean array as one would get with normal Numpy
|
|
|
|
|
|
array comparison. Previously this returned a scalar True or False,
|
|
|
|
|
|
with True only if the comparison was true for all elements compared,
|
|
|
|
|
|
which could lead to confusing circumstances. [#3912]
|
|
|
|
|
|
- Using ``model.inverse = None`` to reset a model's inverse to its
|
|
|
|
|
|
default is deprecated. In the future this syntax will explicitly make
|
|
|
|
|
|
a model not have an inverse (even if it has a default). Instead, use
|
|
|
|
|
|
``del model.inverse`` to reset a model's inverse to its default (if it
|
|
|
|
|
|
has a default, otherwise this just deletes any custom inverse that has
|
|
|
|
|
|
been assigned to the model and is still equivalent to setting
|
|
|
|
|
|
``model.inverse = None``). [#4236]
|
|
|
|
|
|
- Adds a ``model.has_user_inverse`` attribute which indicates whether or not
|
|
|
|
|
|
a user has assigned a custom inverse to ``model.inverse``. This is just
|
|
|
|
|
|
for informational purposes, for example, for software that introspects
|
|
|
|
|
|
model objects. [#4236]
|
|
|
|
|
|
- Renamed the parameters of ``RotateNative2Celestial`` and
|
|
|
|
|
|
``RotateCelestial2Native`` from ``phi``, ``theta``, ``psi`` to
|
|
|
|
|
|
``lon``, ``lat`` and ``lon_pole``. [#3578]
|
|
|
|
|
|
- Deprecated the ``Pix2Sky_AZP.check_mu`` and ``Sky2Pix_AZP.check_mu``
|
|
|
|
|
|
methods (these were obscure "accidentally public" methods that were
|
|
|
|
|
|
probably not used by anyone). [#3910]
|
|
|
|
|
|
- Added a phase parameter to the Sine1D model. [#3807]
|
|
|
|
|
|
- ``astropy.stats``
|
|
|
|
|
|
- Renamed the ``sigma_clip`` ``sig`` keyword as ``sigma``. [#3595]
|
|
|
|
|
|
- Changed the ``sigma_clip`` ``varfunc`` keyword to ``stdfunc``. [#3595]
|
|
|
|
|
|
- Renamed the ``sigma_clipped_stats`` ``mask_val`` keyword to
|
|
|
|
|
|
``mask_value``. [#3595]
|
|
|
|
|
|
- Changed the default ``iters`` keyword value to 5 in both the
|
|
|
|
|
|
``sigma_clip`` and ``sigma_clipped_stats`` functions. [#4067]
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- ``Table.as_array()`` always returns a structured array with each column in
|
|
|
|
|
|
the system's native byte order. The optional ``keep_byteorder=True``
|
|
|
|
|
|
option will keep each column's data in its original byteorder. [#4080]
|
|
|
|
|
|
- ``Table.simple_table()`` now creates tables with int64 and float64 types
|
|
|
|
|
|
instead of int32 and float64. [#4114]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- The ``astropy_time`` attribute and time format has been removed from the
|
|
|
|
|
|
public interface. Existing code that instantiates a new time object using
|
|
|
|
|
|
``format='astropy_time'`` can simply omit the ``format``
|
|
|
|
|
|
specification. [#3857]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- Single-item ``Quantity`` instances with record ``dtype`` will now have
|
|
|
|
|
|
their ``isscalar`` property return ``True``, consistent with behaviour for
|
|
|
|
|
|
numpy arrays, where ``np.void`` records are considered scalar. [#3899]
|
|
|
|
|
|
- Three changes relating to the FITS unit format [#3993]:
|
|
|
|
|
|
- The FITS unit format will no longer parse an arbitrary number as a
|
|
|
|
|
|
scale value. It must be a power of 10 of the form ``10^^k``,
|
|
|
|
|
|
``10^k``, ``10+k``, ``10-k`` and ``10(k)``. [#3993]
|
|
|
|
|
|
- Scales that are powers of 10 can be written out. Previously, any
|
|
|
|
|
|
non-1.0 scale was rejected.
|
|
|
|
|
|
- The ``*`` character is accepted as a separator between the scale
|
|
|
|
|
|
and the units.
|
|
|
|
|
|
- Unit formatter classes now require the ``parse`` and ``to_string``
|
|
|
|
|
|
methods are now required to be classmethods (and the formatter
|
|
|
|
|
|
classes themselves are assumed to be singletons that are not
|
|
|
|
|
|
instantiated). As unit formatters are mostly an internal implementation
|
|
|
|
|
|
detail this is not likely to affect any users. [#4001]
|
|
|
|
|
|
- CGS E&M units are now defined separately from SI E&M units, and have
|
|
|
|
|
|
distinct physical types. [#4255]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- All of the ``get_pkg_data_*`` functions take an optional ``package``
|
|
|
|
|
|
argument as their second positional argument. So any code that previously
|
|
|
|
|
|
passed other arguments to these functions as positional arguments might
|
|
|
|
|
|
break. Use keyword argument passing instead to mitigate this. [#4079]
|
|
|
|
|
|
- ``astropy.utils.iers`` now uses a ``QTable`` internally, which means that
|
|
|
|
|
|
the numerical columns are stored as ``Quantity``, with full support for
|
|
|
|
|
|
units. Furthermore, the ``ut1_utc`` method now returns a ``Quantity``
|
|
|
|
|
|
instead of a float or an array (as did ``pm_xy`` already). [#3223]
|
|
|
|
|
|
- ``astropy.utils.iers`` now throws an ``IERSRangeError``, a subclass
|
|
|
|
|
|
of ``IndexError``, rather than a raw ``IndexError``. This allows more
|
|
|
|
|
|
fine-grained catching of situations where a ``Time`` is beyond the range
|
|
|
|
|
|
of the loaded IERS tables. [#4302]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- When compiled with wcslib 5.9 or later, the FITS headers returned
|
|
|
|
|
|
by ``astropy.wcs.WCS.to_header`` and
|
|
|
|
|
|
``astropy.wcs.WCS.to_header_string`` now include values with more
|
|
|
|
|
|
precision. This will result in numerical differences in your
|
|
|
|
|
|
results if you convert ``astropy.wcs.WCS`` objects to FITS headers
|
|
|
|
|
|
and use the results.
|
|
|
|
|
|
- If NAXIS1 or NAXIS2 is not passed with the header object to
|
|
|
|
|
|
WCS.calc_footprint, a ValueError is raised. [#3557]
|
|
|
|
|
|
+ Bug fixes
|
|
|
|
|
|
- ``astropy.constants``
|
|
|
|
|
|
- The constants ``Ry`` and ``u`` are now properly used inside the
|
|
|
|
|
|
corresponding units. The latter have changed slightly as a result. [#4229]
|
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
|
- Internally, ``coordinates`` now consistently uses the appropriate time
|
|
|
|
|
|
scales for using ERFA functions. [#4302]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- Fix a segfault in the fast C parser when one of the column headers
|
|
|
|
|
|
is empty [#3545].
|
|
|
|
|
|
- Fix several bugs that prevented the fast readers from being used
|
|
|
|
|
|
when guessing the file format. Also improved the read trace
|
|
|
|
|
|
information to better understand format guessing. [#4115]
|
|
|
|
|
|
- Fix an underlying problem that resulted in an uncaught TypeError
|
|
|
|
|
|
exception when reading a CDS-format file with guessing enabled. [#4120]
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- ``Simplex`` fitter now correctly passes additional keywords arguments to
|
|
|
|
|
|
the scipy solver. [#3966]
|
|
|
|
|
|
- The keyword ``acc`` (for accuracy) is now correctly accepted by
|
|
|
|
|
|
``Simplex``. [#3966]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- The units ``Ryd`` and ``u`` are no longer hard-coded numbers, but depend
|
|
|
|
|
|
on the appropriate values in the ``constants`` module. As a result, these
|
|
|
|
|
|
units now imply slightly different conversions. [#4229]
|
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
|
- The ``./setup.py test`` command is now implemented in the ``astropy.tests``
|
|
|
|
|
|
module again (previously its implementation had been moved into
|
|
|
|
|
|
astropy-helpers). However, that made it difficult to synchronize changes
|
|
|
|
|
|
to the Astropy test runner with changes to the ``./setup.py test`` UI.
|
|
|
|
|
|
astropy-helpers v1.1 and above will detect this implementation of the
|
|
|
|
|
|
``test`` command, when present, and use it instead of the old version that
|
|
|
|
|
|
was included in astropy-helpers (most users will not notice any difference
|
|
|
|
|
|
as a result of this change). [#4020]
|
|
|
|
|
|
- The repr for ``Table`` no longer displays ``masked=False`` since tables
|
|
|
|
|
|
are not masked by default anyway. [#3869]
|
|
|
|
|
|
- The version of ``PLY`` that ships with astropy has been updated to 3.6.
|
|
|
|
|
|
- WCSAxes is now required for doc builds. [#4074]
|
|
|
|
|
|
- Updated ``astropy.tests`` test runner code to work with Coverage v4.0 when
|
|
|
|
|
|
generating test coverage reports. [#4176]
|
|
|
|
|
|
- The migration guide from pre-v0.4 coordinates has been removed to avoid
|
|
|
|
|
|
cluttering the ``astropy.coordinates`` documentation with increasingly
|
|
|
|
|
|
irrelevant material. To see the migration guide, we recommend you simply look
|
|
|
|
|
|
to the archived documentation for previous versions, e.g.
|
|
|
|
|
|
http://docs.astropy.org/en/v1.0/coordinates/index.html#migrating-from-pre-v0-4-coordinates
|
|
|
|
|
|
[#4203]
|
|
|
|
|
|
- In ``astropy.coordinates``, the transformations between GCRS, CIRS,
|
|
|
|
|
|
and ITRS have been adjusted to more logically reflect the order in
|
|
|
|
|
|
which they actually apply. This should not affect most coordinate
|
|
|
|
|
|
transformations, but may affect code that is especially sensitive to
|
|
|
|
|
|
machine precision effects that change when the order in which
|
|
|
|
|
|
transformations occur is changed. [#4255]

|
- update to version 1.0.8 (2016-01-08)
|
|
|
|
|
|
+ Bug Fixes
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- Fixed an bug where updates to string columns in FITS tables were not saved
|
|
|
|
|
|
on Python 3. [#4452]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- In-place peak-to-peak calculations now work on ``Quantity``. [#4442]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- Fixed ``find_api_page`` to work correctly on python 3.x [#4378]
|
|
|
|
|
|
- update to version 1.0.7:
|
|
|
|
|
|
* New Features
|
|
|
|
|
|
+ astropy.time
|
|
|
|
|
|
Fix incorrect value attribute for epoch formats like "unix" when
|
|
|
|
|
|
scale is different from the class epoch_scale. [#4313]
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
+ astropy.coordinates
|
|
|
|
|
|
Pickling of EarthLocation instances now also works on Python
|
|
|
|
|
|
2. [#4304]
|
|
|
|
|
|
+ astropy.io.fits
|
|
|
|
|
|
o Fixed a regression that could cause writes of large FITS files
|
|
|
|
|
|
to be truncated. [#4307]
|
|
|
|
|
|
o Astropy v1.0.6 included a fix (#4228) for an obscure case where
|
|
|
|
|
|
the TDIM of a table column is smaller than the repeat count of
|
|
|
|
|
|
its data format. This updates that fix in such a way that it
|
|
|
|
|
|
works with Numpy 1.10 as well. [#4266]
|
|
|
|
|
|
o Fix fast writer so bytestring column output is not prefixed by
|
|
|
|
|
|
'b' in Python 3. [#4350]
|
|
|
|
|
|
+ astropy.table
|
|
|
|
|
|
o Fix a bug when pickling a Table with mixin columns
|
|
|
|
|
|
(e.g. Time). [#4098]
|
|
|
|
|
|
+ astropy.utils
|
|
|
|
|
|
o Fixed an issue where if ipython is installed but ipykernel is
|
|
|
|
|
|
not installed then importing astropy from the ipython console
|
|
|
|
|
|
gave an IPython.kernel deprecation warning. [#4279]
|
|
|
|
|
|
o Fixed crash that could occur in ProgressBar when astropy is
|
|
|
|
|
|
imported in an IPython startup script. [#4274]
|
|
|
|
|
|
- update to version 1.0.6:
|
|
|
|
|
|
* astropy.analytic_functions
|
|
|
|
|
|
+ Fixed blackbody analytic functions to properly support arrays of
|
|
|
|
|
|
temperatures. [#4251]
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
+ Fixed errors in transformations for objects within a few AU of
|
|
|
|
|
|
the Earth. Included substansive changes to transformation
|
|
|
|
|
|
machinery that may change distances at levels ~machine precision
|
|
|
|
|
|
for other objects. [#4254]
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
+ fitsdiff and related functions now do a better job reporting
|
|
|
|
|
|
differences between values that are different types but have the
|
|
|
|
|
|
same representation (ex: the string '0' versus the number
|
|
|
|
|
|
0). [#4122]
|
|
|
|
|
|
+ Miscellaneous fixes for supporting Numpy 1.10. [#4228]
|
|
|
|
|
|
+ Fixed an issue where writing a column of unicode strings to a
|
|
|
|
|
|
FITS table resulted in a quadrupling of size of the column
|
|
|
|
|
|
(i.e. the format of the FITS column was 4 characters for every
|
|
|
|
|
|
one in the original strings). [#4228]
|
|
|
|
|
|
+ Added support for an obscure case (but nonetheless allowed by the
|
|
|
|
|
|
FITS standard) where a column has some TDIMn keyword, but a
|
|
|
|
|
|
repeat count in the TFORMn column greater than the number of
|
|
|
|
|
|
elements implied by the TDIMn. For example TFORMn = 100I, but
|
|
|
|
|
|
TDIMn = '(5,5)'. In this case the TDIMn implies 5x5 arrays in the
|
|
|
|
|
|
column, but the TFORMn implies a 100 element 1-D array in the
|
|
|
|
|
|
column. In this case the TDIM takes precedence, and the remaining
|
|
|
|
|
|
bytes in the column are ignored. [#4228]
|
|
|
|
|
|
* astropy.io.votable
|
|
|
|
|
|
+ Fixed crash with Python compiler optimization level = 2. [#4231]
|
|
|
|
|
|
* astropy.vo
|
|
|
|
|
|
+ Fixed check_conesearch_sites with parallel=True on Python >= 3.3
|
|
|
|
|
|
and on Windows (it was broken in both those cases for separate
|
|
|
|
|
|
reasons). [#2970]
|
|
|
|
|
|
* All tests now pass against Numpy v1.10.x. This implies nominal
|
|
|
|
|
|
support for Numpy 1.10.x moving forward (but there may still be
|
|
|
|
|
|
unknown issues). For example, there is already a known performance
|
|
|
|
|
|
issue with tables containing large multi-dimensional columns--for
|
|
|
|
|
|
example, tables that contain entire images in one or more of their
|
|
|
|
|
|
columns. This is a known upstream issue in Numpy. [#4259]

> Somewhat improved resource usage for FITS data--previously a new ``mmap``
|
|
|
|
|
|
was opened for each HDU of a FITS file accessed through an ``HDUList``.
|
|
|
|
|
|
Each ``mmap`` used up a single file descriptor, causing problems with
|
|
|
|
|
|
system resource limits for some users. Now only a single ``mmap`` is
|
|
|
|
|
|
opened, and shared for the data of all HDUs. Note: The problem still
|
|
|
|
|
|
persists with using the "convenience" functions. For example using
|
|
|
|
|
|
``fits.getdata`` will create one ``mmap`` per HDU read this way (as
|
|
|
|
|
|
opposed to opening the file with ``fits.open`` and accessing the HDUs
|
|
|
|
|

through the ``HDUList`` object). [#4097]

Initializing an ``NDData`` subclass from a parent instance

|
> ``console`` was updated to support IPython 4.x and Jupyter 1.x.

This should supress a ShimWarning that was appearing at

+ Other Changes and Additions
|
|
|
|
|
|
- Astropy now supports Python 3.5. [#4027]
|
|
|
|
|
|
- Updated bundled version of astropy-helpers to 1.0.5. [#4215]
|
|
|
|
|
|
- Updated tests to support py.test 2.7, and upgraded the bundled copy of
|
|
|
|
|
|
py.test to v2.7.3. [#4027]
|
|
|
|
|
|
- Update to 1.0.4
|
|
|
|
|
|
+ New Features
|
|
|
|
|
|
* ``astropy.convolution``
|
|
|
|
|
|
> Modified Cython functions to release the GIL. This enables convolution
|
|
|
|
|
|
to be parallelized effectively and gives large speedups when used with
|
|
|
|
|
|
multithreaded task schedulers such as Dask. [#3949]
|
|
|
|
|
|
+ API Changes
|
|
|
|
|
|
* ``astropy.coordinates``
|
|
|
|
|
|
> Some transformations for an input coordinate that's a scalar now correctly
|
|
|
|
|
|
return a scalar. This was always the intended behavior, but it may break
|
|
|
|
|
|
code that has been written to work-around this bug, so it may be viewed as
|
|
|
|
|
|
an unplanned API change [#3920]
|
|
|
|
|
|
* ``astropy.visualization``
|
|
|
|
|
|
> The ``astropy_mpl_style`` no longer sets ``interactive`` to ``True``, but
|
|
|
|
|
|
instead leaves it at the user preference. This makes using the style
|
|
|
|
|
|
compatible with building docs with Sphinx, and other non-interactive
|
|
|
|
|
|
contexts. [#4030]
|
|
|
|
|
|
+ Bug Fixes
|
|
|
|
|
|
* ``astropy.coordinates``
|
|
|
|
|
|
> Fix bug where coordinate representation setting gets reset to default value
|
|
|
|
|
|
when coordinate array is indexed or sliced. [#3824]
|
|
|
|

> Fixed confusing warning message shown when using dates outside current IERS
|
|
|
|
|
|
data. [#3844]
|
|
|
|
|
|
> ``get_sun`` now yields a scalar when the input time is a scalar (this was a
|
|
|
|
|
|
regression in v1.0.3 from v1.0.2) [#3998]
|
|
|
|
|
|
> Fixed bug where some scalar coordinates were incorrectly being changed to
|
|
|
|
|
|
length-1 array coordinates after transforming through certain frames.
|
|
|
|
|
|
[#3920]
|
|
|

> Fixed bug causing the ``separation`` methods of ``SkyCoord`` and frame
|
|
|
|
|
|
classes to fail due to infinite recursion [#4033]
|
|
|
|
|
|
> Made it so that passing in a list of ``SkyCoord`` objects that are in
|
|
|
|
|
|
UnitSphericalRepresentation to the ``SkyCoord`` constructor appropriately

|
|
* ``astropy.cosmology``

* ``astropy.io.fits``
|
|
|
|
|

> Fixed crash when updating data in a random groups HDU opened in update
|
|
|
|
|
|
mode. [#3730]
|
|
|
|
|
|
> Fixed incorrect checksum / datasum being written when re-writing a scaled
|
|
|
|
|
|
HDU (i.e. non-trivial BSCALE and/or BZERO) with
|
|
|
|
|
|
``do_not_scale_image_data=False``. [#3883]
|
|
|
|
|
|
> Fixed stray deprecation warning in ``BinTableHDU.copy()``. [#3789]
|
|
|
|
|
|
> Better handling of the ``BLANK`` keyword when auto-scaling scaled image
|
|
|
|
|
|
data. The ``BLANK`` keyword is now removed from the header after
|
|
|
|
|
|
auto-scaling is applied, and it is restored properly (with floating point
|
|
|
|
|
|
NaNs replaced by the filler value) when updating a file opened with the
|
|
|
|
|
|
``scale_back=True`` argument. Invalid usage of the ``BLANK`` keyword is
|
|
|
|
|
|
also better warned about during validation. [#3865]
|
|
|
|
|
|
> Reading memmaped scaled images won't fail when
|
|
|
|
|
|
``do_not_scale_image_data=True`` (that is, since we're just reading the raw
|
|
|
|
|
|
/ physical data there is no reason mmap can't be used). [#3766]
|
|
|
|
|
|
> Fixed a reference cycle that could sometimes cause FITS table-related
|
|
|
|
|
|
objects (``BinTableHDU``, ``ColDefs``, etc.) to hang around in memory
|
|
|
|
|
|
longer than expected. [#4012]
|
|
|
|
|
|
* ``astropy.modeling``
|
|
|
|
|
|
> Added missing default values for ``Ellipse2D`` parameters. [#3903]
|
|
|
|
|
|
> Improved support for pickling of compound models, including both compound
|
|
|
|
|
|
model instances, and new compound model classes. [#3867]
|
|
|
|
|
|
* ``astropy.table``
|
|
|
|
|
|
> Added missing default values for ``Ellipse2D`` parameters. [#3903]
|
|
|
|
|
|
* ``astropy.time``
|
|
|
|
|
|
> Fixed iteration of scalar ``Time`` objects so that ``iter()`` correctly
|
|
|
|
|
|
raises a ``TypeError`` on them (while still allowing ``Time`` arrays to be
|
|
|
|
|
|
iterated). [#4048]
|
|
|
|
|
|
* ``astropy.units``
|
|
|
|
|
|
> Added frequency-equivalency check when declaring doppler equivalencies
|
|
|
|
|
|
[#3728]
|
|
|
|
|
|
> Define ``floor_divide`` (``//``) for ``Quantity`` to be consistent
|
|
|
|
|
|
``divmod``, such that it only works where the quotient is dimensionless.
|
|
|
|
|
|
This guarantees that ``(q1 // q2) * q2 + (q1 % q2) == q1``. [#3817]
|
|
|
|
|
|
> Fixed the documentation of supported units to correctly report support for
|
|
|
|
|
|
SI prefixes. Previously the table of supported units incorrectly showed
|
|
|
|
|
|
several derived unit as not supporting prefixes, when in fact they do.
|
|
|
|
|
|
[#3835]
|
|
|
|
|
|
> Fix a crash when calling ``astropy.units.cds.enable()``. This will now
|
|
|
|
|
|
"set" rather than "add" units to the active set to avoid the namespace
|
|
|
|
|
|
clash with the default units. [#3873]
|
|
|
|
|
|
> Ensure in-place operations on ``float32`` quantities work. [#4007]
|
|
|
|
|
|
* ``astropy.utils``
|
|
|
|
|
|
> The ``deprecated`` decorator did not correctly wrap classes that have a
|
|
|
|
|
|
custom metaclass--the metaclass could be dropped from the deprecated
|
|
|
|
|
|
version of the class. [#3997]
|
|
|
|
|
|
> The ``wraps`` decorator would copy the wrapped function's name to the
|
|
|
|
|
|
wrapper function even when ``'__name__'`` is excluded from the ``assigned``

|
|
|
|
|
|
* Misc
|
|
|
|
|
|
> ``fitscheck`` no longer causes scaled image data to be rescaled when
|
|
|
|
|
|
adding checksums to existing files. [#3884]
|
|
|
|
|
|
> Fixed an issue where running ``import astropy`` from within the source
|
|
|
|
|
|
tree did not automatically build the extension modules if the source is
|
|
|
|
|
|
from a source distribution (as opposed to a git repository). [#3932]
|
|
|
|
|
|
> Fixed multiple instances of a bug that prevented Astropy from being used
|
|
|
|
|
|
when compiled with the ``python -OO`` flag, due to it causing all
|
|
|
|
|
|
docstrings to be stripped out. [#3923]
|
|
|
|
|
|
> Removed source code template files that were being installed
|
|
|
|
|
|
accidentally alongside installed Python modules. [#4014]
|
|
|
|
|
|
> Fixed a bug in the exception logging that caused a crash in the exception
|
|
|
|
|
|
handler itself on Python 3 when exceptions do not include a message.
|
|

|
|
- update to version 1.0.3:
|
|
|
|
|
|
* New Features
|
|
|
|
|
|
+ astropy.table
|
|
|
|
|
|
o Greatly improved the speed of printing a large table to the
|
|
|
|
|
|
screen when only a few rows are being displayed. [#3796]
|
|
|
|
|
|
+ astropy.time
|
|
|
|
|
|
o Add support for the 2015-Jun-30 leap second. [#3794]
|
|
|
|
|
|
* API Changes
|
|
|
|
|
|
+ astropy.io.ascii
|
|
|
|
|
|
o Note that HTML formatted tables will not always be found with
|
|
|
|
|
|
guess mode unless it passes certain heuristics that strongly
|
|
|
|
|
|
suggest the presence of HTML in the input. Code that expects
|
|
|
|
|
|
to read tables from HTML should specify format='html'
|
|
|
|
|
|
explicitly. See bug fixes below for more details. [#3693]
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
+ astropy.convolution
|
|
|
|
|
|
o Fix issue with repeated normalizations of Kernels. [#3747]
|
|
|
|
|
|
+ astropy.coordinates
|
|
|
|
|
|
o Fixed get_sun to yield frames with the obstime set to what's
|
|
|
|
|
|
passed into the function (previously it incorrectly always had
|
|
|
|
|
|
J2000). [#3750]
|
|
|
|
|
|
o Fixed get_sun to account for aberration of light. [#3750]
|
|
|
|
|
|
o Fixed error in the GCRS->ICRS transformation that gave
|
|
|
|
|
|
incorrect distances. [#3750]
|
|
|
|
|
|
+ astropy.io.ascii
|
|
|
|
|
|
o Remove HTML from the list of automatically-guessed formats
|
|
|
|
|
|
when reading if the file does not appear to be HTML. This was
|
|
|
|
|
|
necessary to avoid a commonly-encountered segmentation fault
|
|
|
|
|
|
occurring in the libxml parser on MacOSX. [#3693]
|
|
|
|
|
|
+ astropy.io.fits
|
|
|
|
|
|
o Fixes to support the upcoming Numpy 1.10. [#3419]
|
|
|
|
|
|
|
|
|
|
|
|
+ astropy.modeling
|
|
|
|
|
|
o Polynomials are now scaled when used in a compound
|
|
|
|
|
|
model. [#3702]
|
|
|
|
|
|
o Fixed the Ellipse2D model to be consistent with Disk2D in how
|
|
|
|
|
|
pixels are included. [#3736]
|
|
|
|
|
|
o Fixed crash when evaluating a model that accepts no
|
|
|
|
|
|
inputs. [#3772]
|
|
|
|
|
|
+ astropy.testing
|
|
|
|
|
|
o The Astropy py.test plugins that disable unintential internet
|
|
|
|
|
|
access in tests were also blocking use of local UNIX sockets
|
|
|
|
|
|
in tests, which prevented testing some multiprocessing
|
|
|
|
|
|
code--fixed. [#3713]
|
|
|
|
|
|
+ astropy.units
|
|
|
|
|
|
o Supported full SI prefixes for the barn unit ("picobarn",
|
|
|
|
|
|
"femtobarn", etc.) [#3753]
|
|
|
|
|
|
o Fix loss of precision when multiplying non-whole-numbered
|
|
|
|
|
|
powers of units together. For example, before this change,
|
|
|
|
|
|
(u.m ** 1.5) ** Fraction(4, 5) resulted in an inaccurate
|
|
|
|
|
|
floating-point power of 1.2000000000000002. After this change,
|
|
|
|
|
|
the exact rational number of Fraction(6, 5) is
|
|
|
|
|
|
maintained. [#3790]
|
|
|
|
|
|
o Fixed printing of object ndarrays containing multiple Quantity
|
|
|
|
|
|
objects with differing / incompatible units. Note: Unit
|
|
|
|
|
|
conversion errors now cause a UnitConversionError exception to
|
|
|
|
|
|
be raised. However, this is a subclass of the UnitsError
|
|
|
|
|
|
exception used previously, so existing code that catches
|
|
|
|
|
|
UnitsError should still work. [#3778]
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
- Added a new astropy.__bibtex__ attribute which gives a citation
|
|
|
|
|
|
for Astropy in bibtex format. [#3697]
|
|
|
|
|
|
- The bundled version of ERFA was updated to v1.2.0 to address
|
|
|
|
|
|
leapscond updates. [#3802]

- update to version 1.0.2:
|
|
|
|
|
|
* New Features
|
|
|
|
|
|
+ "astropy.modeling"
|
|
|
|
|

o Added support for polynomials with degree 0 or degree greater
|
|
|
|
|
|
than 15. [#3574, 3589]
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
+ "astropy.config"
|
|
|
|
|
|
o The pre-astropy-0.4 configuration API has been fixed. It was
|
|
|
|
|
|
inadvertently broken in 1.0.1. [#3627]
|
|
|
|
|
|
+ "astropy.io.fits"
|
|
|
|
|
|
o Fixed handling of BINTABLE with TDIMn of size 1. [#3580]
|
|
|
|
|
|
o Fixed a severe memory leak that occurred when reading tile
|
|
|
|
|
|
compressed images. [#3680]
|
|
|
|
|
|
o Fixed bug where column data could be unintentionally
|
|
|
|
|
|
byte-swapped when copying data from an existing FITS file to a
|
|
|
|
|
|
new FITS table with a TDIMn keyword for that column. [#3561]
|
|
|
|
|
|
o The "ColDefs.change_attrib", "ColDefs.change_name", and
|
|
|
|
|
|
"ColDefs.change_unit" methods now work as advertised. It is
|
|
|
|
|
|
also possible (and preferable) to update attributes directly
|
|
|
|
|
|
on "Column" objects (for example setting "column.name"), and
|
|
|
|
|
|
the change will be accurately reflected in any associated
|
|
|
|
|
|
table data and its FITS header. [#3283, #1539, #2618]
|
|
|
|
|
|
o Fixes an issue with the "FITS_rec" interface to FITS table
|
|
|
|
|
|
data, where a "FITS_rec" created by copying an existing FITS
|
|
|
|
|
|
table but adding new rows could not be sliced or masked
|
|
|
|
|
|
correctly. [#3641]
|
|
|
|
|
|
+ "astropy.io.votable"
|
|
|
|
|
|
o Loading a "TABLE" element without any "DATA" now correctly
|
|
|
|
|
|
creates a 0-row array. [#3636]
|
|
|
|
|
|
+ "astropy.modeling"
|
|
|
|
|
|
o Added workaround to support inverses on compound models when
|
|
|
|
|
|
one of the sub-models is itself a compound model with a
|
|
|
|
|
|
manually-assigned custom inverse. [#3542]
|
|
|
|
|
|
o Fixed instantiation of polynomial models with constraints for
|
|
|
|
|
|
parameters (constraints could still be assigned after
|
|
|
|
|
|
instantiation, but not during). [#3606]
|
|
|
|
|
|
o Fixed fitting of 2D polynomial models with the
|
|
|
|
|
|
"LeVMarLSQFitter". [#3606]
|
|
|
|
|
|
+ "astropy.table"
|
|
|
|
|
|
o Ensure "QTable" can be pickled [#3590]
|
|
|
|
|
|
o Some corner cases when instantiating an "astropy.table.Table"
|
|
|
|
|
|
with a Numpy array are handled [#3637]. Notably:
|
|
|
|
|
|
o a zero-length array is the same as passing "None"
|
|
|
|
|
|
o a scalar raises a "ValueError"
|
|
|
|
|
|
o a one-dimensional array is treated as a single row of a table.
|
|
|
|
|
|
+ "astropy.time"
|
|
|
|
|
|
o Ensure a "Column" without units is treated as an "array", not
|
|
|
|
|
|
as an
|
|
|
|
|
|
o Ensure a "Column" without units is treated as an "array", not
|
|
|
|
|
|
as an dimensionless "Quantity". [#3648]

|
+ "astropy.units"
|
|
|
|
|
|
o Ensure equivalencies that do more than just scale a "Quantity"
|
|
|
|
|
|
are properly handled also in "ufunc" evaluations. [#2496,
|
|
|
|
|
|
#3586]
|
|
|
|
|
|
o The LaTeX representation of the Angstrom unit has changed from
|
|
|
|
|
|
"\overset{\circ}{A}" to "\mathring{A}", which should have
|
|
|
|
|
|
better support across regular LaTeX, MathJax and matplotlib
|
|
|
|
|
|
(as of version 1.5) [#3617]
|
|
|
|
|
|
+ "astropy.vo"
|
|
|
|
|
|
o Using HTTPS/SSL for communication between SAMP hubs now works
|
|
|
|
|
|
correctly on all supported versions of Python [#3613]
|
|
|
|
|
|
+ "astropy.wcs"
|
|
|
|
|
|
o When no "relax" argument is passed to "WCS.to_header()" and
|
|
|
|
|
|
the result omits non-standard WCS keywords, a warning is
|
|
|
|
|
|
emitted. [#3652]
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
+ Nothing changed yet.
|
|
|
|
|
|
+ "astropy.units"
|
|
|
|
|
|
o Clarified imperial mass measurements and added pound force
|
|
|
|
|
|
(lbf), kilopound (kip), and pound per square inch
|
|
|
|
|
|
(psi). [#3409]
|
|
|
|
|
|
+ "astropy.vo"
|
|
|
|
|
|
o The number of retries for connections in "astropy.vo.samp" can
|
|
|
|
|
|
now be configured by a "n_retries" configuration
|
|
|
|
|
|
option. [#3612]
|
|
|
|
|
|
+ Testing
|
|
|
|
|
|
o Running "astropy.test()" from within the IPython prompt has
|
|
|
|
|
|
been provisionally re-enabled. [#3184]
|
|
|
|
|
|
- update to version 1.0.1:
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
- astropy.constants
|
|
|
|
|
|
+ Ensure constants can be turned into Quantity safely. [#3537, #3538]
|
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
|
+ Fix a segfault in the fast C parser when one of the column headers is empty [#3545].
|
|
|
|
|
|
+ Fixed support for reading inf and nan values with the fast
|
|
|
|
|
|
reader in Windows. Also fixed in the case of using
|
|
|
|
|
|
use_fast_converter=True with the fast reader. [#3525]
|
|
|
|
|
|
+ Fixed use of mmap in the fast reader on Windows. [#3525]
|
|
|
|
|
|
+ Fixed issue where commented header would treat comments
|
|
|
|
|
|
defining the table (i.e. column headers) as purely information
|
|
|
|
|
|
comments, leading to problems when trying to round-trip the
|
|
|
|
|
|
table. [#3562]
|
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
|
+ Fixed propagation of parameter constraints ('fixed', 'bounds',
|
|
|
|
|
|
'tied') between compound models and their components. There is
|
|
|
|
|
|
may still be some difficulty defining 'tied' constraints
|
|
|
|
|
|
properly for use with compound models, however. [#3481]
|
|
|
|
|
|
- astropy.nddata
|
|
|
|
|
|
+ Restore several properties to the compatibility class
|
|
|
|
|
|
NDDataArray that were inadvertently omitted [#3466].
|
|
|
|
|
|
- astropy.time
|
|
|
|
|
|
+ Time objects now always evalutate to True, except when
|
|
|
|
|
|
empty. [#3530]
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
- Updated bundled astropy-helpers version to v1.0.1 to address
|
|
|
|
|
|
installation issues with some packages that depend on
|
|
|
|
|
|
Astropy. [#3541]
|
|
|
|
|
|
* Miscellaneous
|
|
|
|
|
|
- astropy._erfa
|
|
|
|
|
|
+ The ERFA wrappers are now written directly in the Python/C API
|
|
|
|
|
|
rather than using Cython, for greater performance. [#3521]
|
|
|
|
|
|
- Improve import time of astropy [#3488].
|
|
|
|
|
|
- specfile: added fits2bitmap binary
|
|
|
|
|
|
- update to version 1.0:
|
|
|
|
|
|
* General
|
|
|
|
|
|
- Astropy now requires a Numpy 1.6.0 or later.
|
|
|
|
|
|
* New Features
|
|
|
|
|
|
- astropy.analytic_functions
|
|
|
|
|
|
+ The astropy.analytic_functions was added to contain analytic
|
|
|
|
|
|
functions useful for astronomy [#3077].
|
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
|
+ astropy.coordinates now has a full stack of frames allowing
|
|
|
|
|
|
transformations from ICRS or other celestial systems down to
|
|
|
|
|
|
Alt/Az coordinates. [#3217]
|
|
|
|
|
|
+ astropy.coordinates now has a get_sun function that gives the
|
|
|
|
|
|
coordinates of the Sun at a specified time. [#3217]
|
|
|
|
|
|
+ SkyCoord now has to_pixel and from_pixel methods that convert
|
|
|
|
|
|
between celestial coordinates as SkyCoord objects and pixel
|
|
|
|
|
|
coordinates given an astropy.wcs.WCS object. [#3002]
|
|
|
|
|
|
+ SkyCoord now has search_around_sky and search_around_3d
|
|
|
|
|
|
convenience methods that allow searching for all coordinates
|
|
|
|
|
|
within a certain distance of another SkyCoord. [#2953]
|
|
|
|
|
|
+ SkyCoord can now accept a frame instance for the frame= keyword
|
|
|
|
|
|
argument. [#3063]
|
|
|
|
|
|
+ SkyCoord now has a guess_from_table method that can be used to
|
|
|
|
|
|
quickly create SkyCoord objects from an astropy.table.Table
|
|
|
|
|
|
object. [#2951]
|
|
|
|
|
|
+ astropy.coordinates now has a Galactocentric frame, a coordinate
|
|
|
|
|
|
frame centered on a (user specified) center of the Milky
|
|
|
|
|
|
Way. [#2761, #3286]
|
|
|
|
|
|
+ SkyCoord now accepts more formats of the coordinate string when
|
|
|
|
|
|
the representation has ra and dec attributes. [#2920]
|
|
|
|
|
|
+ SkyCoord can now accept lists of SkyCoord objects, frame
|
|
|
|
|
|
objects, or representation objects and will combine them into a
|
|
|
|
|
|
single object. [#3285]
|
|
|
|
|
|
+ Frames and SkyCoord instances now have a method
|
|
|
|
|
|
is_equivalent_frame that can be used to check that two frames
|
|
|
|
|
|
are equivalent (ignoring the data). [#3330]
|
|
|
|
|
|
+ The __repr__ of coordinate objects now shows scalar coordinates
|
|
|
|
|
|
in the same format as vector coordinates. [#3350, 3448]
|
|
|
|
|
|
- astropy.cosmology
|
|
|
|
|
|
+ Added lookback_distance, which is c * lookback_time. [#3145]
|
|
|
|
|
|
+ Add baryonic matter density and dark matter only density
|
|
|
|
|
|
parameters to cosmology objects [#2757].
|
|
|
|
|
|
+ Add a clone method to cosmology objects to allow copies of
|
|
|
|
|
|
cosmological objects to be created with the specified variables
|
|
|
|
|
|
modified [#2592].
|
|
|
|
|
|
+ Increase default numerical precision of z_at_value following the
|
|
|
|
|
|
accurate by default, fast by explicit request model [#3074].
|
|
|
|
|
|
+ Cosmology functions that take a single (redshift) input now
|
|
|
|
|
|
broadcast like numpy ufuncs. So, passing an arbitrarily shaped
|
|
|
|
|
|
array of inputs will produce an output of the same
|
|
|
|
|
|
shape. [#3178, #3194]
|
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
|
+ Simplify the way new Reader classes are defined, allowing custom
|
|
|
|
|
|
behavior entirely by overriding inherited class attributes
|
|
|
|
|
|
instead of setting instance attributes in the Reader __init__
|
|
|
|
|
|
method. [#2812]
|
|
|
|
|
|
+ There is now a faster C/Cython engine available for reading and
|
|
|
|
|
|
writing simple ASCII formats like CSV. Both are enabled by
|
|
|
|
|
|
default, and fast reading will fall back on an ordinary reader
|
|
|
|
|
|
in case of a parsing failure. Their behavior can be altered with
|
|
|
|
|
|
the parameter fast_reader in read and fast_writer in
|
|
|
|
|
|
write. [#2716]
|
|
|
|
|
|
+ Make Latex/AASTex tables use unit attribute of Column for
|
|
|
|
|
|
output. [#3064]
|
|
|
|
|
|
+ Store comment lines encountered during reading in metadata of
|
|
|
|
|
|
the output table via meta['comment_lines']. [#3222]
|
|
|
|
|
|
+ Write comment lines in Table metadata during output for all
|
|
|
|
|
|
basic formats, IPAC, and fast writers. This functionality can be
|
|
|
|
|
|
disabled with comment=False. [#3255]
|
|
|
|
|
|
+ Add reader / writer for the Enhanced CSV format which stores
|
|
|
|
|
|
table and column meta data, in particular data type and
|
|
|
|
|
|
unit. [#2319]
|
|
|
|
|
|
+ Automatically use guess=False when reading if the file format is
|
|
|
|
|
|
provided and the format parameters are uniquely specified. This
|
|
|
|
|
|
update also removes duplicate format guesses to improve
|
|
|
|
|
|
performance. [#3418]
|
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
|
+ The fitsdiff script ignores some things by default when
|
|
|
|
|
|
comparing fits files (e.g. empty header lines). This adds a
|
|
|
|
|
|
--exact option where nothing is ignored. [#2782, #3110]
|
|
|
|
|
|
+ The fitsheader script now takes a --keyword option to extract a
|
|
|
|
|
|
specific keyword from the header of a FITS file, and a --table
|
|
|
|
|
|
option to export headers into any of the data formats supported
|
|
|
|
|
|
by astropy.table. [#2555, #2588]
|
|
|
|
|
|
+ Section now supports all advanced indexing features ndarray does
|
|
|
|
|
|
(slices with any steps, integer arrays, boolean arrays, None,
|
|
|
|
|
|
Ellipsis). It also properly returns scalars when this is
|
|
|
|
|
|
appropriate. [#3148]
|
|
|
|
|
|
- astropy.io.votable
|
|
|
|
|
|
+ astropy.io.votable.parse now takes a datatype_mapping keyword
|
|
|
|
|
|
argument to map invalid datatype names to valid ones in order to
|
|
|
|
|
|
support non-compliant files. [#2675]
|
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
|
+ Added the capability of creating new "compound" models by
|
|
|
|
|
|
combining existing models using arithmetic operators. See the
|
|
|
|
|
|
"What's New in 1.0" page in the Astropy documentation for more
|
|
|
|
|
|
details. [#3231]
|
|
|
|
|
|
+ A new custom_model decorator/factory function has been added for
|
|
|
|
|
|
converting normal functions to Model classes that can work
|
|
|
|
|
|
within the Astropy modeling framework. This replaces the old
|
|
|
|
|
|
custom_model_1d function which is now deprecated. The new
|
|
|
|
|
|
function works the same as the old one but is less limited in
|
|
|
|
|
|
the types of models it can be used to created. [#1763]
|
|
|
|
|
|
+ The Model and Fitter classes have .registry attributes which
|
|
|
|
|
|
provide sets of all loaded Model and Fitter classes (this is
|
|
|
|
|
|
useful for building UIs for models and fitting). [#2725]
|
|
|
|
|
|
+ A dict-like meta member was added to Model. it is to be used to
|
|
|
|
|
|
store any optional information which is relevant to a project
|
|
|
|
|
|
and is not in the standard Model class. [#2189]
|
|
|
|
|
|
+ Added Ellipse2D model. [#3124]
|
|
|
|
|
|
- astropy.nddata
|
|
|
|
|
|
+ New array-related utility functions in astropy.nddata.utils for
|
|
|
|
|
|
adding and removing arrays from other arrays with different
|
|
|
|
|
|
sizes/shapes. [#3201]
|
|
|
|
|
|
+ New metaclass NDDataBase for enforcing the nddata interface in
|
|
|
|
|
|
subclasses without restricting implementation of the data
|
|
|
|
|
|
storage. [#2905]
|
|
|
|
|
|
+ New mixin classes NDSlicingMixin for slicing, NDArithmeticMixin
|
|
|
|
|
|
for arithmetic operations, and NDIOMixin for input/ouput in
|
|
|
|
|
|
NDData. [#2905]
|
|
|
|
|
|
+ Added a decorator support_nddata that can be used to write
|
|
|
|
|
|
functions that can either take separate arguments or NDData
|
|
|
|
|
|
objects. [#2855]
|
|
|
|
|
|
- astropy.stats
|
|
|
|
|
|
+ Added mad_std() function. [#3208]
|
|
|
|
|
|
+ Added gaussian_fwhm_to_sigma and gaussian_sigma_to_fwhm
|
|
|
|
|
|
constants. [#3208]
|
|
|
|
|
|
+ New function sigma_clipped_stats which can be used to quickly
|
|
|
|
|
|
get common statistics for an array, using sigma clipping at the
|
|
|
|
|
|
same time. [#3201]
|
|
|
|
|
|
- astropy.table
|
|
|
|
|
|
+ Changed the internal implementation of the Table class changed
|
|
|
|
|
|
so that it no longer uses numpy structured arrays as the core
|
|
|
|
|
|
table data container. [#2790, #3179]
|
|
|
|
|
|
+ Tables can now be written to an html file that includes
|
|
|
|
|
|
interactive browsing capabilities. To write out to this format,
|
|
|
|
|
|
use Table.write('filename.html', format='jsviewer'). [#2875]
|
|
|
|
|
|
+ A quantity property and to method were added to Table columns
|
|
|
|
|
|
that allow the column values to be easily converted to
|
|
|
|
|
|
astropy.units.Quantity objects. [#2950]
|
|
|
|
|
|
+ Add unique convenience method to table. [#3185]
|
|
|
|
|
|
- astropy.tests
|
|
|
|
|
|
+ Added a new Quantity-aware assert_quantity_allclose. [#3273]
|
|
|
|
|
|
- astropy.time
|
|
|
|
|
|
+ Time can now handle arbitrary array dimensions, with operations
|
|
|
|
|
|
following standard numpy broadcasting rules. [#3138]
|
|
|
|
|
|
- astropy.units
|
|
|
|
|
|
+ Support for VOUnit has been updated to be compliant with version
|
|
|
|
|
|
1.0 of the standard. [#2901]
|
|
|
|
|
|
+ Added an insert method to insert values into a Quantity object.
|
|
|
|
|
|
This is similar to the numpy.insert function. [#3049]
|
|
|
|
|
|
+ When viewed in IPython, Quantity objects with array values now
|
|
|
|
|
|
render using LaTeX and scientific notation. [#2271]
|
|
|
|
|
|
+ Added units.quantity_input decorator to validate quantity inputs
|
|
|
|
|
|
to a function for unit compatibility. [#3072]
|
|
|
|
|
|
+ Added units.astronomical_unit as a long form for
|
|
|
|
|
|
units.au. [#3303]
|
|
|
|
|
|
- astropy.utils
|
|
|
|
|
|
+ Added a new decorator astropy.utils.wraps which acts as a
|
|
|
|
|
|
replacement for the standard library's functools.wraps, the only
|
|
|
|
|
|
difference being that the decorated function also preserves the
|
|
|
|
|
|
wrapped function's call signature. [#2849]
|
|
|
|
|
|
+ astropy.utils.compat.numpy has been revised such that it can
|
|
|
|
|
|
include patched versions of routines from newer numpy versions.
|
|
|
|
|
|
The first addition is a version of broadcast_arrays that can be
|
|
|
|
|
|
used with Quantity and other ndarray subclasses (using the
|
|
|
|
|
|
subok=True flag). [#2327]
|
|
|
|
|
|
+ Added astropy.utils.resolve_name which returns a member of a
|
|
|
|
|
|
module or class given the fully qualified dotted name of that
|
|
|
|
|
|
object as a string. [#3389]
|
|
|
|
|
|
+ Added astropy.utils.minversion which can be used to check
|
|
|
|
|
|
minimum version requirements of Python modules (to test for
|
|
|
|
|
|
specific features and/ or bugs and the like). [#3389]
|
|
|
|
|
|
- astropy.visualization
|
|
|
|
|
|
+ Created astropy.visualization module and added functionality
|
|
|
|
|
|
relating to image normalization (i.e. stretching and scaling) as
|
|
|
|
|
|
well as a new script fits2bitmap that can produce a bitmap image
|
|
|
|
|
|
from a FITS file. [#3201]
|
|
|
|
|
|
+ Added dictionary
|
|
|
|
|
|
astropy.visualization.mpl_style.astropy_mpl_style which can be
|
|
|
|
|
|
used to set a uniform plotstyle specifically for tutorials that
|
|
|
|
|
|
is improved compared to matplotlib defaults. [#2719, #2787,
|
|
|
|
|
|
#3200]
|
|
|
|
|
|
- astropy.wcs
|
|
|
|
|
|
+ wcslib has been upgraded to version 4.25. This brings a single
|
|
|
|
|
|
new feature:
|
|
|
|
|
|
+ equinox and radesys will now be given default values conforming
|
|
|
|
|
|
with the WCS specification if EQUINOXa and RADESYa,
|
|
|
|
|
|
respectively, are not present in the header.
|
|
|
|
|
|
+ The minimum required version of wcslib is now 4.24. [#2503]
|
|
|
|
|
|
+ Added a new function wcs_to_celestial_frame that can be used to
|
|
|
|
|
|
find the astropy.coordinates celestial frame corresponding to a
|
|
|
|
|
|
particular WCS. [#2730]
|
|
|
|
|
|
+ astropy.wcs.WCS.compare now supports a tolerance keyword
|
|
|
|
|
|
argument to allow for approximate comparison of floating-point
|
|
|
|
|
|
values. [#2503]
|
|
|
|
|
|
+ added pixel_scale_matrix, celestial, is_celestial, and
|
|
|
|
|
|
has_celestial convenience attributes. Added
|
|
|
|
|
|
proj_plane_pixel_scales, proj_plane_pixel_area, and
|
|
|
|
|
|
non_celestial_pixel_scales utility functions for retrieving WCS
|
|
|
|
|
|
pixel scale and area information [#2832, #3304]
|
|
|
|
|
|
+ Added two functions pixel_to_skycoord and skycoord_to_pixel that
|
|
|
|
|
|
make it easy to convert between SkyCoord objects and pixel
|
|
|
|
|
|
coordinates. [#2885]
|
|
|
|
|
|
+ all_world2pix now uses a much more sophisticated and complete
|
|
|
|
|
|
algorithm to iteratively compute the inverse WCS
|
|
|
|
|
|
transform. [#2816]
|
|
|
|
|
|
+ Add ability to use WCS object to define projections in
|
|
|
|
|
|
Matplotlib, using the WCSAxes package. [#3183]
|
|
|
|
|
|
+ Added is_proj_plane_distorted for testing if pixels are
|
|
|
|
|
|
distorted. [#3329]
|
|
|
|
|
|
- Misc
|
|
|
|
|
|
+ astropy._erfa was added as a new subpackage wrapping the
|
|
|
|
|
|
functionality of the ERFA library in python. This is primarily
|
|
|
|
|
|
of use for other astropy subpackages, but the API may be made
|
|
|
|
|
|
more public in the future. [#2992]
|
|
|
|
|
|
* API Changes
|
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
|
+ Subclasses of BaseCoordinateFrame which define a custom repr
|
|
|
|
|
|
should be aware of the format expected in SkyCoord.__repr__(),
|
|
|
|
|
|
which changed in this release. [#2704, #2882]
|
|
|
|
|
|
+ The CartesianPoints class (deprecated in v0.4) has now been
|
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
|
+ The previous astropy.coordinates.builtin_frames module is now a
|
|
|
|
|
|
subpackage. Everything that was in the
|
|
|
|
|
|
astropy.coordinates.builtin_frames module is still accessible
|
|
|
|
|
|
from the new package, but the classes are now in separate
|
|
|
|
|
|
modules. This should have no direct impact at the user
|
|
|
|
|
|
level. [#3120]
|
|
|
|
|
|
+ Support for passing a frame as a positional argument in the
|
|
|
|
|
|
SkyCoord class has now been deprecated, except in the case where
|
|
|
|
|
|
a frame with data is passed as the sole positional
|
|
|
|
|
|
argument. [#3152]
|
|
|
|
|
|
+ Improved __repr__ of coordinate objects representing a single
|
|
|
|
|
|
coordinate point for the sake of easier copy/pasting. [#3350]
|
|
|
|
|
|
- astropy.cosmology
|
|
|
|
|
|
+ The functional interface to the cosmological routines as well as
|
|
|
|
|
|
set_current and get_current (deprecated in v0.4) have now been
|
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
|
+ Added a new argument to htmldict in the HTML reader named
|
|
|
|
|
|
parser, which allows the user to specify which parser
|
|
|
|
|
|
BeautifulSoup should use as a backend. [#2815]
|
|
|
|
|
|
+ Add FixedWidthTwoLine reader to guessing. This will allows to
|
|
|
|
|
|
read tables that a copied from screen output like print my_table
|
|
|
|
|
|
to be read automatically. Discussed in #3025 and #3099 [#3109]
|
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
|
+ A new optional argument cache has been added to
|
|
|
|
|
|
astropy.io.fits.open(). When opening a FITS file from a URL,
|
|
|
|
|
|
cache is a boolean value specifying whether or not to save the
|
|
|
|
|
|
file locally in Astropy's download cache (True by
|
|
|
|
|
|
default). [#3041]
|
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
|
+ Model classes should now specify inputs and outputs class
|
|
|
|
|
|
attributes instead of the old n_inputs and n_outputs. These
|
|
|
|
|
|
should be tuples providing human-readable *labels* for all
|
|
|
|
|
|
inputs and outputs of the model. The length of the tuple
|
|
|
|
|
|
indicates the numbers of inputs and outputs. See "What's New in
|
|
|
|
|
|
Astropy 1.0" for more details. [#2835]
|
|
|
|
|
|
+ It is no longer necessary to include __init__ or __call__
|
|
|
|
|
|
definitions in Model subclasses if all they do is wrap the
|
|
|
|
|
|
super-method in order to provide a nice call signature to the
|
|
|
|
|
|
docs. The inputs class attribute is now used to generate a nice
|
|
|
|
|
|
call signature, so these methods should only be overridden by
|
|
|
|
|
|
Model subclasses in order to provide new functionality. [#2835]
|
|
|
|
|
|
+ Most models included in Astropy now have sensible default values
|
|
|
|
|
|
for most or all of their parameters. Call help(ModelClass) on
|
|
|
|
|
|
any model to check what those defaults are. Most of them time
|
|
|
|
|
|
they should be overridden, but some of them are useful (for
|
|
|
|
|
|
example spatial offsets are always set at the origin by
|
|
|
|
|
|
default). Another rule of thumb is that, where possible, default
|
|
|
|
|
|
parameters are set so that the model is a no-op, or close to it,
|
|
|
|
|
|
by default. [#2932]
|
|
|
|
|
|
+ The Model.inverse method has been changed to a *property*, so
|
|
|
|
|
|
that now accessing model.inverse on a model returns a new model
|
|
|
|
|
|
that implements that model's inverse, and *calling*
|
|
|
|
|
|
model.inverse(...)` on some independent variable computes the
|
|
|
|
|
|
value of the inverse (similar to what the old Model.invert()
|
|
|
|
|
|
method was meant to do). [#3024]
|
|
|
|
|
|
+ The Model.invert() method has been removed entirely (it was
|
|
|
|
|
|
never implemented and there should not be any existing code that
|
|
|
|
|
|
relies on it). [#3024]
|
|
|
|
|
|
+ custom_model_1d is deprecated in favor of the new custom_model
|
|
|
|
|
|
(see "New Features" above). [#1763]
|
|
|
|
|
|
+ The Model.param_dim property (deprecated in v0.4) has now been
|
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
|
+ The Beta1D and Beta2D models have been renamed to Moffat1D and
|
|
|
|
|
|
Moffat2D. [#3029]
|
|
|
|
|
|
- astropy.nddata
|
|
|
|
|
|
+ flags, shape, size, dtype and ndim properties removed from
|
|
|
|
|
|
astropy.nddata.NDData. [#2905]
|
|
|
|
|
|
+ Arithmetic operations, uncertainty propagation, slicing and
|
|
|
|
|
|
automatic conversion to a numpy array removed from
|
|
|
|
|
|
astropy.nddata.NDData. The class astropy.nddata.NDDataArray is
|
|
|
|
|
|
functionally equivalent to the old NDData. [#2905]
|
|
|
|
|
|
- astropy.table
|
|
|
|
|
|
+ The Column.units property (deprecated in v0.3) has now been
|
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
|
+ The Row.data and Table._data attributes have been deprecated
|
|
|
|
|
|
related to the change in Table implementation. They are
|
|
|
|
|
|
replaced by Row.as_void() and Table.as_array() methods,
|
|
|
|
|
|
respectively. [#2790]
|
|
|
|
|
|
+ The Table.create_mask method has been removed. This
|
|
|
|
|
|
undocumented method was a development orphan and would cause
|
|
|
|
|
|
corruption of the table if called. [#2790]
|
|
|
|
|
|
+ The return type for integer item access to a Column
|
|
|
|
|
|
(e.g. col[12] or t['a'][12]) is now always a numpy scalar, numpy
|
|
|
|
|
|
ndarray, or numpy MaskedArray. Previously if the column was
|
|
|
|
|
|
multidimensional then a Column object would be returned. [#3095]
|
|
|
|
|
|
+ The representation of Table and Column objects has been changed
|
|
|
|
|
|
to be formatted similar to the print output. [#3239]
|
|
|
|
|
|
- astropy.time
|
|
|
|
|
|
+ The Time.val and Time.vals properties (deprecated in v0.3) and
|
|
|
|
|
|
the Time.lon, and Time.lat properties (deprecated in v0.4) have
|
|
|
|
|
|
now been removed. [#2990]
|
|
|
|
|
|
+ Add decimalyear format that represents time as a decimal
|
|
|
|
|
|
year. [#3265]
|
|
|
|
|
|
- astropy.units
|
|
|
|
|
|
+ Support for VOUnit has been updated to be compliant with version
|
|
|
|
|
|
1.0 of the standard. This means that some VOUnit strings that
|
|
|
|
|
|
were rejected before are now acceptable. [#2901] Notably:
|
|
|
|
|
|
- SI prefixes are supported on most units
|
|
|
|
|
|
- Binary prefixes are supported on "bits" and "bytes"
|
|
|
|
|
|
- Custom units can be defined "inline" by placing them between single
|
|
|
|
|
|
quotes.
|
|
|
|
|
|
+ Unit.get_converter has been deprecated. It is not strictly
|
|
|
|
|
|
necessary for end users, and it was confusing due to lack of
|
|
|
|
|
|
support for Quantity objects. [#3456]
|
|
|
|
|
|
- astropy.utils
|
|
|
|
|
|
+ Some members of astropy.utils.misc were moved into new
|
|
|
|
|
|
submodules. Specifically:
|
|
|
|
|
|
- deprecated, deprecated_attribute, and lazyproperty ->
|
|
|
|
|
|
astropy.utils.decorators
|
|
|
|
|
|
- find_current_module, find_mod_objs ->
|
|
|
|
|
|
astropy.utils.introspection
|
|
|
|
|
|
All of these functions can be imported directly from
|
|
|
|
|
|
astropy.utils which should be preferred over referencing
|
|
|
|
|
|
individual submodules of astropy.utils. [#2857]
|
|
|
|
|
|
+ The ProgressBar.iterate class method (deprecated in v0.3) has
|
|
|
|
|
|
now been removed. [#2990]
|
|
|
|
|
|
+ Updated astropy/utils/console.py ProgressBar() module to display
|
|
|
|
|
|
output to IPython notebook with the addition of an interactive
|
|
|
|
|
|
kwarg. [#2658] [#2789]
|
|
|
|
|
|
- astropy.wcs
|
|
|
|
|
|
+ The WCS.calcFootprint method (deprecated in v0.4) has now been
|
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
|
+ An invalid unit in a CUNITn keyword now displays a warning and
|
|
|
|
|
|
returns a UnrecognizedUnit instance rather than raising an
|
|
|
|
|
|
exception [#3190]
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
- astropy.convolution
|
|
|
|
|
|
+ astropy.convolution.discretize_model now handles arbitrary
|
|
|
|
|
|
callables correctly [#2274].
|
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
|
+ Angle.to_string now outputs unicode arrays instead of object
|
|
|
|
|
|
arrays. [#2981]
|
|
|
|
|
|
+ SkyCoord.to_string no longer gives an error when used with an
|
|
|
|
|
|
array coordinate with more than one dimension. [#3340]
|
|
|
|
|
|
+ Fixed support for subclasses of UnitSphericalRepresentation and
|
|
|
|
|
|
SphericalRepresentation [#3354, #3366]
|
|
|
|
|
|
+ Fixed latex display of array angles in IPython notebook. [#3480]
|
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
|
+ In the CommentedHeader the data_start parameter now defaults to
|
|
|
|
|
|
0, which is the first uncommented line. Discussed in
|
|
|
|
|
|
#2692. [#3054]
|
|
|
|
|
|
+ Position lines in FixedWidthTwoLine reader could consist of many
|
|
|
|
|
|
characters. Now, only one character in addition to the
|
|
|
|
|
|
delimiter is allowed. This bug was discovered as part of [#3109]
|
|
|
|
|
|
+ The IPAC table writer now consistently uses the fill_values
|
|
|
|
|
|
keyword to specify the output null values. Previously the
|
|
|
|
|
|
behavior was inconsistent or incorrect. [#3259]
|
|
|
|
|
|
+ The IPAC table reader now correctly interprets abbreviated
|
|
|
|
|
|
column types. [#3279]
|
|
|
|
|
|
+ Tables that look almost, but not quite like DAOPhot tables could
|
|
|
|
|
|
cause guessing to fail. [#3342]
|
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
|
+ Fixed the problem in fits.open of some filenames with colon (:)
|
|
|
|
|
|
in the name being recognized as URLs instead of file
|
|
|
|
|
|
names. [#3122]
|
|
|
|
|
|
+ Setting memmap=True in fits.open and related functions now
|
|
|
|
|
|
raises a ValueError if opening a file in memory-mapped mode is
|
|
|
|
|
|
impossible. [#2298]
|
|
|
|
|
|
+ CONTINUE cards no longer end the value of the final card in the
|
|
|
|
|
|
series with an ampersand, per the specification of the CONTINUE
|
|
|
|
|
|
card convention. [#3282]
|
|
|
|
|
|
+ Fixed a crash that occurred when reading an ASCII table
|
|
|
|
|
|
containing zero-precision floating point fields. [#3422]
|
|
|
|
|
|
+ When a float field for an ASCII table has zero-precision a
|
|
|
|
|
|
decimal point (with no digits following it) is still written to
|
|
|
|
|
|
the field as long as there is space for it, as recommended by
|
|
|
|
|
|
the FITS standard. This makes it less ambiguous that these
|
|
|
|
|
|
columns should be interpreted as floats. [#3422]
|
|
|
|
|
|
- astropy.logger
|
|
|
|
|
|
+ Fix a bug that occurred when displaying warnings that produced
|
|
|
|
|
|
an error message dictionary changed size during
|
|
|
|
|
|
iteration. [#3353]
|
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
|
+ Fixed a bug in SLSQPLSQFitter where the maxiter argument was not
|
|
|
|
|
|
passed correctly to the optimizer. [#3339]
|
|
|
|
|
|
- astropy.table
|
|
|
|
|
|
+ Fix a problem where table.hstack fails to stack multiple
|
|
|
|
|
|
references to the same table, e.g. table.hstack([t, t]). [#2995]
|
|
|
|
|
|
+ Fixed a problem where table.vstack and table.hstack failed to
|
|
|
|
|
|
stack a single table, e.g. table.vstack([t]). [#3313]
|
|
|
|
|
|
+ Fix a problem when doing nested iterators on a single
|
|
|
|
|
|
table. [#3358]
|
|
|
|
|
|
+ Fix an error when an empty list, tuple, or ndarray is used for
|
|
|
|
|
|
item access within a table. This now returns the table with no
|
|
|
|
|
|
rows. [#3442]
|
|
|
|
|
|
- astropy.time
|
|
|
|
|
|
+ When creating a Time object from a datetime object the time zone
|
|
|
|
|
|
info is now correctly used. [#3160]
|
|
|
|
|
|
+ For Time objects, it is now checked that numerical input is
|
|
|
|
|
|
finite. [#3396]
|
|
|
|
|
|
- astropy.units
|
|
|
|
|
|
+ Added a latex_inline unit format that returns the units in LaTeX
|
|
|
|
|
|
math notation with negative exponents instead of fractions
|
|
|
|
|
|
[#2622].
|
|
|
|
|
|
+ When using a unit that is deprecated in a given unit format,
|
|
|
|
|
|
non-deprecated alternatives will be suggested. [#2806] For
|
|
|
|
|
|
example::
|
|
|
|
|
|
>>> import astropy.units as u
|
|
|
|
|
|
>>> u.Unit('Angstrom', format='fits')
|
|
|
|
|
|
WARNING: UnitsWarning: The unit 'Angstrom' has been deprecated
|
|
|
|
|
|
in the FITS standard. Suggested: nm (with data multiplied by
|
|
|
|
|
|
0.1). [astropy.units.format.utils]
|
|
|
|
|
|
- astropy.utils
|
|
|
|
|
|
+ treat_deprecations_as_exceptions has been fixed to recognize
|
|
|
|
|
|
Astropy deprecation warnings. [#3015]
|
|
|
|
|
|
- astropy.wcs
|
|
|
|
|
|
+ astropy.wcs.WCS.sub now accepts unicode strings as input on
|
|
|
|
|
|
Python 2.x [#3356]
|
|
|
|
|
|
- Misc
|
|
|
|
|
|
+ Some modules and tests that would crash upon import when using a
|
|
|
|
|
|
non-final release of Numpy (e.g. 1.9.0rc1). [#3471]
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
- The bundled copy of astropy-helpers has been updated to
|
|
|
|
|
|
v1.0. [#3515]
|
|
|
|
|
|
- The bundled copy of astropy-helpers has been updated to
|
|
|
|
|
|
v1.0. [#3513]
|
|
|
|
|
|
- Updated astropy.extern.configobj to Version 5. Version 5 uses
|
|
|
|
|
|
six and the same code covers both Python 2 and Python 3. [#3149]
|
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
|
+ The repr of SkyCoord and coordinate frame classes now separate
|
|
|
|
|
|
frame attributes and coordinate information. [#2704, #2882]
|
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
|
+ Overwriting an existing file using the clobber=True option no
|
|
|
|
|
|
longer displays a warning message. [#1963]
|
|
|
|
|
|
+ fits.open no longer catches OSError exceptions on missing or
|
|
|
|
|
|
unreadable files-- instead it raises the standard Python
|
|
|
|
|
|
exceptions in such cases. [#2756, #2785]
|
|
|
|
|
|
- astropy.table
|
|
|
|
|
|
+ Sped up setting of Column slices by an order of
|
|
|
|
|
|
magnitude. [#2994, #3020]
|
|
|
|
|
|
- Updated the bundled six module to version 1.7.3 and made 1.7.3
|
|
|
|
|
|
the minimum acceptable version of six. [#2814]
|
|
|
|
|
|
- The version of ERFA included with Astropy is now v1.1.1 [#2971]
|
|
|
|
|
|
- The code base is now fully Python 2 and 3 compatible and no
|
|
|
|
|
|
longer requires 2to3. [#2033]
|
|
|
|
|
|
- `funcsigs <https://pypi.python.org/pypi/funcsigs>`_ is included
|
|
|
|
|
|
in utils.compat, but defaults to the inspect module components
|
|
|
|
|
|
where available (3.3+) [#3151].
|
|
|
|
|
|
- The list of modules displayed in the pytest header can now be
|
|
|
|
|
|
customized. [#3157]
|
|
|
|
|
|
- `jinja2 <http://jinja.pocoo.org/docs/dev/>`_>=2.7 is now
|
|
|
|
|
|
required to build the source code from the git repository, in
|
|
|
|
|
|
order to allow the ERFA wrappers to be generated. [#3166]
|
|
|
|
|
|
- update to version 0.4.4:
|
|
|
|
|
|
* astropy.vo.samp
|
|
|
|
|
|
+ astropy.vo.samp is now usable on Python builds that do not
|
|
|
|
|
|
support the SSLv3 protocol (which depends both on the version of
|
|
|
|
|
|
Python and the version of OpenSSL or LibreSSL that it is built
|
|
|
|
|
|
against.) [#3308]
|
|
|
|
|
|
+ The default SSL protocol used is now determined from the default
|
|
|
|
|
|
used in the Python ssl standard library. This default may be
|
|
|
|
|
|
different depending on the exact version of Python you are
|
|
|
|
|
|
using. [#3308]
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
+ WCS allows slices of the form slice(None, x, y), which
|
|
|
|
|
|
previously resulted in an unsliced copy being returned (note:
|
|
|
|
|
|
this was previously incorrectly reported as fixed in v0.4.3)
|
|
|
|
|
|
[#2909]
|
|
|
|
|
|
- changes from version 0.4.3:
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
+ The Distance class has been fixed to no longer rely on the
|
|
|
|
|
|
deprecated cosmology functions. [#2991]
|
|
|
|
|
|
+ Ensure float32 values can be used in coordinate
|
|
|
|
|
|
representations. [#2983]
|
|
|
|
|
|
+ Fix frame attribute inheritance in SkyCoord.transform_to()
|
|
|
|
|
|
method so that the default attribute value (e.g. equinox) for
|
|
|
|
|
|
the destination frame gets used if no corresponding value was
|
|
|
|
|
|
explicitly specified. [#3106]
|
|
|
|
|
|
+ Angle accepts hours:mins or deg:mins initializers (without
|
|
|
|
|
|
seconds). In these cases float minutes are also accepted.
|
|
|
|
|
|
+ astropy.coordinates.SkyCoord objects are now copyable. [#2888 ]
|
|
|
|
|
|
+ astropy.coordinates.SkyCoord object attributes are now
|
|
|
|
|
|
immutable. It is still technically possible to change the
|
|
|
|
|
|
internal data for an array-valued coordinate object but this
|
|
|
|
|
|
leads to inconsistencies [#2889] and should not be done. [#2888]
|
|
|
|
|
|
* astropy.cosmology
|
|
|
|
|
|
+ The ztol keyword argument to z_at_value now works correctly
|
|
|
|
|
|
[#2993].
|
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
|
+ Fix a bug in Python 3 when guessing file format using a file
|
|
|
|
|
|
object as input. Also improve performance in same situation for
|
|
|
|
|
|
Python 2. [#3132]
|
|
|
|
|
|
+ Fix a problem where URL was being downloaded for each
|
|
|
|
|
|
guess. [#2001]
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
+ The in operator now works correctly for checking if an extension
|
|
|
|
|
|
is in an HDUList (as given via EXTNAME, (EXTNAME, EXTVER)
|
|
|
|
|
|
tuples, etc.) [#3060]
|
|
|
|
|
|
+ Added workaround for bug in MacOS X <= 10.8 that caused
|
|
|
|
|
|
np.fromfile to fail. [#3078]
|
|
|
|
|
|
+ Added support for the RICE_ONE compression type synonym. [#3115]
|
|
|
|
|
|
* astropy.modeling
|
|
|
|
|
|
+ Fixed a test failure on Debian/PowerPC and Debian/s390x. [#2708]
|
|
|
|
|
|
+ Fixed crash in evaluating models that have more outputs than
|
|
|
|
|
|
inputs--this case may not be handled as desired for all
|
|
|
|
|
|
conceivable models of this format (some may have to implement
|
|
|
|
|
|
custom prepare_inputs and prepare_outputs methods). But as long
|
|
|
|
|
|
as all outputs can be assumed to have a shape determined from
|
|
|
|
|
|
the broadcast of all inputs with all parameters then this can be
|
|
|
|
|
|
used safely. [#3250]
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
+ Fix a bug that caused join to fail for multi-dimensional
|
|
|
|
|
|
columns. [#2984]
|
|
|
|
|
|
+ Fix a bug where MaskedColumn attributes which had been changed
|
|
|
|
|
|
since the object was created were not being carried through when
|
|
|
|
|
|
slicing. [#3023]
|
|
|
|
|
|
+ Fix a bug that prevented initializing a table from a structured
|
|
|
|
|
|
array with multi-dimensional columns with copy=True. [#3034]
|
|
|
|
|
|
+ Fixed unnecessarily large unicode columns when instantiating a
|
|
|
|
|
|
table from row data on Python 3. [#3052]
|
|
|
|
|
|
+ Improved the warning message when unable to aggregate
|
|
|
|
|
|
non-numeric columns. [#2700]
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
+ Operations on quantities with incompatible types now raises a
|
|
|
|
|
|
much more informative TypeError. [#2934]
|
|
|
|
|
|
+ Quantity.tolist now overrides the ndarray method to give a
|
|
|
|
|
|
NotImplementedError (by renaming the previous list
|
|
|
|
|
|
method). [#3050]
|
|
|
|
|
|
+ Quantity.round now always returns a Quantity (previously it
|
|
|
|
|
|
returned an ndarray for decimals>0). [#3062]
|
|
|
|
|
|
+ Ensured np.squeeze always returns a Quantity (it only worked if
|
|
|
|
|
|
no dimensions were removed). [#3045]
|
|
|
|
|
|
+ Input to Quantity with a unit attribute no longer can get
|
|
|
|
|
|
mangled with copy=False. [#3051]
|
|
|
|
|
|
+ Remove trailing space in __format__ calls for dimensionless
|
|
|
|
|
|
quantities. [#3097]
|
|
|
|
|
|
+ Comparisons between units and non-unit-like objects now works
|
|
|
|
|
|
correctly. [#3108]
|
|
|
|
|
|
+ Units with fractional powers are now correctly multiplied
|
|
|
|
|
|
together by using rational arithmetic. [#3121]
|
|
|
|
|
|
+ Removed a few entries from spectral density equivalencies which
|
|
|
|
|
|
did not make sense. [#3153]
|
|
|
|
|
|
* astropy.utils
|
|
|
|
|
|
+ Fixed an issue with the deprecated decorator on classes that
|
|
|
|
|
|
invoke super() in their __init__ method. [#3004]
|
|
|
|
|
|
+ Fixed a bug which caused the metadata_conflicts parameter to be
|
|
|
|
|
|
ignored in the astropy.utils.metadata.merge function. [#3294]
|
|
|
|
|
|
* astropy.vo
|
|
|
|
|
|
+ Fixed an issue with reconnecting to a SAMP Hub. [#2674 ]
|
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
|
+ Invalid or out of range values passed to wcs_world2pix will now
|
|
|
|
|
|
be correctly identified and returned as nan values. [#2965]
|
|
|
|
|
|
+ Fixed an issue which meant that Python thought WCS objects were
|
|
|
|
|
|
iterable. [#3066]
|
|
|
|
|
|
* Misc
|
|
|
|
|
|
+ Astropy will now work if your Python interpreter does not have
|
|
|
|
|
|
the bz2 module installed. [#3104]
|
|
|
|
|
|
+ Fixed ResourceWarning for astropy/extern/bundled/six.py that
|
|
|
|
|
|
could occur sometimes after using Astropy in Python 3.4. [#3156]
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
+ Improved the agreement of the FK5 <-> Galactic conversion with
|
|
|
|
|
|
other codes, and with the FK5 <-> FK4 <-> Galactic
|
|
|
|
|
|
route. [#3107]
|
|
|
|
|
|
- specfile:
|
|
|
|
|
|
* update copyright year
|
|
|
|
|
|
* added libhdf5 requirement
|
|
|
|
|
|
- update to version 0.4.2:
|
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
|
- Angle accepts hours:mins or deg:mins initializers (without
|
|
|
|
|
|
seconds). In these cases float minutes are also accepted.
|
|
|
|
|
|
- The repr for coordinate frames now displays the frame
|
|
|
|
|
|
attributes (ex: ra, dec) in a consistent order. It should be
|
|
|
|
|
|
noted that as part of this fix, the
|
|
|
|
|
|
BaseCoordinateFrame.get_frame_attr_names() method now returns
|
|
|
|
|
|
an OrderedDict instead of just a dict. [#2845]
|
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
|
- Fixed a crash when reading scaled float data out of a FITS file
|
|
|
|
|
|
that was loaded from a string (using HDUList.fromfile) rather
|
|
|
|
|
|
than from a file. [#2710]
|
|
|
|
|
|
- Fixed a crash when reading data from an HDU whose header
|
|
|
|
|
|
contained in invalid value for the BLANK keyword (e.g., a string
|
|
|
|
|
|
value instead of an integer as required by the FITS
|
|
|
|
|
|
Standard). Invalid BLANK keywords are now warned about, but are
|
|
|
|
|
|
otherwise ignored. [#2711]
|
|
|
|
|
|
- Fixed a crash when reading the header of a tile-compressed HDU
|
|
|
|
|
|
if that header contained invalid duplicate keywords resulting in
|
|
|
|
|
|
a KeyError [#2750]
|
|
|
|
|
|
- Fixed crash when reading gzip-compressed FITS tables through the
|
|
|
|
|
|
Astropy Table interface. [#2783]
|
|
|
|
|
|
- Fixed corruption when writing new FITS files through to gzipped
|
|
|
|
|
|
files. [#2794]
|
|
|
|
|
|
- Fixed crash when writing HDUs made with non-contiguous data
|
|
|
|
|
|
arrays to file-like objects. [#2794]
|
|
|
|
|
|
- It is now possible to create astropy.io.fits.BinTableHDU objects
|
|
|
|
|
|
with a table with zero rows. [#2916]
|
|
|
|
|
|
* astropy.io.misc
|
|
|
|
|
|
- Fixed a bug that prevented h5py Dataset objects from being
|
|
|
|
|
|
automatically recognized by Table.read. [#2831]
|
|
|
|
|
|
* astropy.modeling
|
|
|
|
|
|
- Make LevMarLSQFitter work with weights keyword. [#2900]
|
|
|
|
|
|
* astropy.table
|
|
|
|
|
|
- Fixed reference cycle in tables that could prevent Table objects
|
|
|
|
|
|
from being freed from memory. [#2879]
|
|
|
|
|
|
- Fixed an issue where Table.pprint() did not print the header to
|
|
|
|
|
|
stdout when stdout is redirected (say, to a file). [#2878]
|
|
|
|
|
|
- Fixed printing of masked values when a format is
|
|
|
|
|
|
specified. [#1026]
|
|
|
|
|
|
- Ensured that numpy ufuncs that return booleans return plain
|
|
|
|
|
|
ndarray instances, just like the comparison operators. [#2963]
|
|
|
|
|
|
* astropy.time
|
|
|
|
|
|
- Ensure bigendian input to Time works on a little-endian machine
|
|
|
|
|
|
(and vice versa). [#2942]
|
|
|
|
|
|
* astropy.units
|
|
|
|
|
|
- Ensure unit is kept when adding 0 to quantities. [#2968]
|
|
|
|
|
|
* astropy.utils
|
|
|
|
|
|
- Fixed color printing on Windows with IPython 2.0. [#2878]
|
|
|
|
|
|
* astropy.vo
|
|
|
|
|
|
- Improved error message on Cone Search time out. [#2687]
|
|
|
|
|
|
* Fixed a couple issues with files being inappropriately included
|
|
|
|
|
|
and/or excluded from the source archive distributions of
|
|
|
|
|
|
Astropy. [#2843, #2854]
|
|
|
|
|
|
* As part of fixing the fact that masked elements of table columns
|
|
|
|
|
|
could not be printed when a format was specified, the column
|
|
|
|
|
|
format string options were expanded to allow simple specifiers
|
|
|
|
|
|
such as '5.2f'. [#2898]
|
|
|
|
|
|
* Ensure numpy 1.9 is supported. [#2917]
|
|
|
|
|
|
* Ensure numpy master is supported, by making np.cbrt work with
|
|
|
|
|
|
quantities. [#2937]

|
|
|
|
|
|
|
- Mark wcs headers as false positives for devel-file-in-non-devel-package
|
|
|
|
|
|
These are used by the python files so they must be available.
|
|
|
|
|
|
- Update to 0.4.1 (2014-08-08)
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
|
- Fixed a bug where an unedited configuration file from astropy
|
|
|
|
|
|
0.3.2 would not be correctly identified as unedited. [#2772] This
|
|
|
|
|
|
resulted in the warning::
|
|
|
|
|
|
WARNING: ConfigurationChangedWarning: The configuration options
|
|
|
|
|
|
in astropy 0.4 may have changed, your configuration file was not
|
|
|
|
|
|
updated in order to preserve local changes. A new configuration
|
|
|
|
|
|
template has been saved to
|
|
|
|
|
|
'~/.astropy/config/astropy.0.4.cfg'. [astropy.config.configuration]
|
|
|
|
|
|
- Fixed the error message that is displayed when an old
|
|
|
|
|
|
configuration item has moved. Before, the destination
|
|
|
|
|
|
section was wrong. [#2772]
|
|
|
|
|
|
- Added configuration settings for ``io.fits``, ``io.votable`` and
|
|
|
|
|
|
``table.jsviewer`` that were missing from the configuration file
|
|
|
|
|
|
template. [#2772]
|
|
|
|
|
|
- The configuration template is no longer rewritten on every import
|
|
|
|
|
|
of astropy, causing race conditions. [#2805]
|
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|
|
- Fixed the multiplication of ``Kernel`` with numpy floats. [#2174]
|
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
|
- ``Distance`` can now take a list of quantities. [#2261]
|
|
|
|
|
|
- For in-place operations for ``Angle`` instances in which the result unit
|
|
|
|
|
|
is not an angle, an exception is raised before the instance is corrupted.
|
|
|
|
|
|
[#2718]
|
|
|
|
|
|
- ``CartesianPoints`` are now deprecated in favor of
|
|
|
|
|
|
``CartesianRepresentation``. [#2727]
|
|
|
|
|
|
- ``astropy.io.misc``
|
|
|
|
|
|
- An existing table within an HDF5 file can be overwritten without affecting
|
|
|
|
|
|
other datasets in the same HDF5 file by simultaneously using
|
|
|
|
|
|
``overwrite=True`` and ``append=True`` arguments to the ``Table.write``
|
|
|
|
|
|
method. [#2624]
|
|
|
|
|
|
- ``astropy.logger``
|
|
|
|
|
|
- Fixed a crash that could occur in rare cases when (such as in bundled
|
|
|
|
|
|
apps) where submodules of the ``email`` package are not importable. [#2671]
|
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
|
- ``astropy.nddata.NDData()`` no longer raises a ``ValueError`` when passed
|
|
|
|
|
|
a numpy masked array which has no masked entries. [#2784]
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- When saving a table to a FITS file containing a unit that is not
|
|
|
|
|
|
supported by the FITS standard, a warning rather than an exception
|
|
|
|
|
|
is raised. [#2797]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- By default, ``Quantity`` and its subclasses will now convert to float also
|
|
|
|
|
|
numerical types such as ``decimal.Decimal``, which are stored as objects
|
|
|
|
|
|
by numpy. [#1419]
|
|
|
|
|
|
- The units ``count``, ``pixel``, ``voxel`` and ``dbyte`` now output
|
|
|
|
|
|
to FITS, OGIP and VOUnit formats correctly. [#2798]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- Restored missing information from deprecation warning messages
|
|
|
|
|
|
from the ``deprecated`` decorator. [#2811]
|
|
|
|
|
|
- Fixed support for ``staticmethod`` deprecation in the ``deprecated``
|
|
|
|
|
|
decorator. [#2811]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- Fixed a memory leak when ``astropy.wcs.WCS`` objects are copied
|
|
|
|
|
|
[#2754]
|
|
|
|
|
|
- Fixed a crash when passing ``ra_dec_order=True`` to any of the
|
|
|
|
|
|
``*2world`` methods. [#2791]
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
- Bundled copy of astropy-helpers upgraded to v0.4.1. [#2825]
|
|
|
|
|
|
- General improvements to documentation and docstrings [#2722, #2728, #2742]
|
|
|
|
|
|
- Made it easier for third-party packagers to have Astropy use their own
|
|
|
|
|
|
version of the ``six`` module (so long as it meets the minimum version
|
|
|
|
|
|
requirement) and remove the copy bundled with Astropy. See the
|
|
|
|
|
|
astropy/extern/README file in the source tree. [#2623]
|
|
|
|
|
|
- Update to 0.4 (2014-07-16)
|
|
|
|
|
|
* New Features
|
|
|
|
|
|
- ``astropy.constants``
|
|
|
|
|
|
- Added ``b_wien`` to represent Wien wavelength displacement law constant.
|
|
|
|
|
|
[#2194]
|
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|
|
- Changed the input parameter in ``Gaussian1DKernel`` and
|
|
|
|
|
|
``Gaussian2DKernel`` from ``width`` to ``stddev`` [#2085].
|
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
|
- The coordinates package has undergone major changes to implement
|
|
|
|
|
|
`APE5 <https://github.com/astropy/astropy-APEs/blob/master/APE5.rst>`_ .
|
|
|
|
|
|
These include backwards-incompatible changes, as the underlying framework
|
|
|
|
|
|
has changed substantially. See the APE5 text and the package documentation
|
|
|
|
|
|
for more details. [#2422]
|
|
|
|
|
|
- A ``position_angle`` method has been added to the new ``SkyCoord``. [#2487]
|
|
|
|
|
|
- Updated ``Angle.dms`` and ``Angle.hms`` to return ``namedtuple`` -s instead
|
|
|
|
|
|
of regular tuples, and added ``Angle.signed_dms`` attribute that gives the
|
|
|
|
|
|
absolute value of the ``d``, ``m``, and ``s`` along with the sign. [#1988]
|
|
|
|
|
|
- By default, ``Distance`` objects are now required to be positive. To
|
|
|
|
|
|
allow negative values, set ``allow_negative=True`` in the ``Distance``
|
|
|
|
|
|
constructor when creating a ``Distance`` instance.
|
|
|
|
|
|
- ``Longitude`` (resp. ``Latitude``) objects cannot be used any more to
|
|
|
|
|
|
initialize or set ``Latitude`` (resp. ``Longitude``) objects. An explicit
|
|
|
|
|
|
conversion to ``Angle`` is now required. [#2461]
|
|
|
|
|
|
- The deprecated functions for pre-0.3 coordinate object names like
|
|
|
|
|
|
``ICRSCoordinates`` have been removed. [#2422]
|
|
|
|
|
|
- The ``rotation_matrix`` and ``angle_axis`` functions in
|
|
|
|
|
|
``astropy.coordinates.angles`` were made more numerically consistent and
|
|
|
|
|
|
are now tested explicitly [#2619]
|
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
|
- Added ``z_at_value`` function to find the redshift at which a cosmology
|
|
|
|
|
|
function matches a desired value. [#1909]
|
|
|
|
|
|
- Added ``FLRW.differential_comoving_volume`` method to give the differential
|
|
|
|
|
|
comoving volume at redshift z. [#2103]
|
|
|
|
|
|
- The functional interface is now deprecated in favor of the more-explicit
|
|
|
|
|
|
use of methods on cosmology objects. [#2343]
|
|
|
|
|
|
- Updated documentation to reflect the removal of the functional
|
|
|
|
|
|
interface. [#2507]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- The ``astropy.io.ascii`` output formats ``latex`` and ``aastex`` accept a
|
|
|
|
|
|
dictionary called ``latex_dict`` to specify options for LaTeX output. It is
|
|
|
|
|
|
now possible to specify the table alignment within the text via the
|
|
|
|
|
|
``tablealign`` keyword. [#1838]
|
|
|
|
|
|
- If ``header_start`` is specified in a call to ``ascii.get_reader`` or any
|
|
|
|
|
|
method that calls ``get_reader`` (e.g. ``ascii.read``) but ``data_start``
|
|
|
|
|
|
is not specified at the same time, then ``data_start`` is calculated so
|
|
|
|
|
|
that the data starts after the header. Before this, the default was
|
|
|
|
|
|
that the header line was read again as the first data line
|
|
|
|
|
|
[#855 and #1844].
|
|
|
|
|
|
- A new ``csv`` format was added as a convenience for handling CSV (comma-
|
|
|
|
|
|
separated values) data. [#1935]
|
|
|
|
|
|
This format also recognises rows with an inconsistent number of elements.
|
|
|
|
|
|
[#1562]
|
|
|
|
|
|
- An option was added to guess the start of data for CDS format files when
|
|
|
|
|
|
they do not strictly conform to the format standard. [#2241]
|
|
|
|
|
|
- Added an HTML reader and writer to the ``astropy.io.ascii`` package.
|
|
|
|
|
|
Parsing requires the installation of BeautifulSoup and is therefore
|
|
|
|
|
|
an optional feature. [#2160]
|
|
|
|
|
|
- Added support for inputting column descriptions and column units
|
|
|
|
|
|
with the ``io.ascii.SExtractor`` reader. [#2372]
|
|
|
|
|
|
- Allow the use of non-local ReadMe files in the CDS reader. [#2329]
|
|
|
|
|
|
- Provide a mechanism to select how masked values are printed. [#2424]
|
|
|
|
|
|
- Added support for reading multi-aperture daophot file. [#2656]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- Included a new command-line script called ``fitsheader`` to display the
|
|
|
|
|
|
header(s) of a FITS file from the command line. [#2092]
|
|
|
|
|
|
- Added new verification options ``fix+ignore``, ``fix+warn``,
|
|
|
|
|
|
``fix+exception``, ``silentfix+ignore``, ``silentfix+warn``, and
|
|
|
|
|
|
``silentfix+exception`` which give more control over how to report fixable
|
|
|
|
|
|
errors as opposed to unfixable errors.
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- Prototype implementation of fitters that treat optimization algorithms
|
|
|
|
|
|
separately from fit statistics, allowing new fitters to be created by
|
|
|
|
|
|
mixing and matching optimizers and statistic functions. [#1914]
|
|
|
|
|
|
- Slight overhaul to how inputs to and outputs from models are handled with
|
|
|
|
|
|
respect to array-valued parameters and variables, as well as sets of
|
|
|
|
|
|
multiple models. See the associated PR and the modeling section of the
|
|
|
|
|
|
v0.4 documentation for more details. [#2634]
|
|
|
|
|
|
- Added a new ``SimplexLSQFitter`` which uses a downhill simplex optimizer
|
|
|
|
|
|
with a least squares statistic. [#1914]
|
|
|
|
|
|
- Changed ``Gaussian2D`` model such that ``theta`` now increases
|
|
|
|
|
|
counterclockwise. [#2199]
|
|
|
|
|
|
- Replaced the ``MatrixRotation2D`` model with a new model called simply
|
|
|
|
|
|
``Rotation2D`` which requires only an angle to specify the rotation.
|
|
|
|
|
|
The new ``Rotation2D`` rotates in a counter-clockwise sense whereas
|
|
|
|
|
|
the old ``MatrixRotation2D`` increased the angle clockwise.
|
|
|
|
|
|
[#2266, #2269]
|
|
|
|
|
|
- Added a new ``AffineTransformation2D`` model which serves as a
|
|
|
|
|
|
replacement for the capability of ``MatrixRotation2D`` to accept an
|
|
|
|
|
|
arbitrary matrix, while also adding a translation capability. [#2269]
|
|
|
|
|
|
- Added ``GaussianAbsorption1D`` model. [#2215]
|
|
|
|
|
|
- New ``Redshift`` model [#2176].
|
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
|
- Allow initialization ``NDData`` or ``StdDevUncertainty`` with a
|
|
|
|
|
|
``Quantity``. [#2380]
|
|
|
|
|
|
- ``astropy.stats``
|
|
|
|
|
|
- Added flat prior to binom_conf_interval and binned_binom_proportion
|
|
|
|
|
|
- Change default in ``sigma_clip`` from ``np.median`` to ``np.ma.median``.
|
|
|
|
|
|
[#2582]
|
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
|
- Note, the following new features are included in astropy-helpers as well:
|
|
|
|
|
|
- The ``automodapi`` and ``automodsumm`` extensions now include sphinx
|
|
|
|
|
|
configuration options to write out what ``automodapi`` and ``automodsumm``
|
|
|
|
|
|
generate, mainly for debugging purposes. [#1975, #2022]
|
|
|
|
|
|
- Reference documentation now shows functions/class docstrings at the
|
|
|
|
|
|
inteded user-facing API location rather than the actual file where
|
|
|
|
|
|
the implementation is found. [#1826]
|
|
|
|
|
|
- The ``automodsumm`` extension configuration was changed to generate
|
|
|
|
|
|
documentation of class ``__call__`` member functions. [#1817, #2135]
|
|
|
|
|
|
- ``automodapi`` and ``automodsumm`` now have an ``:allowed-package-names:``
|
|
|
|
|
|
option that make it possible to document functions and classes that
|
|
|
|
|
|
are in a different namespace. [#2370]
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- Improved grouped table aggregation by using the numpy ``reduceat()`` method
|
|
|
|
|
|
when possible. This can speed up the operation by a factor of at least 10
|
|
|
|
|
|
to 100 for large unmasked tables and columns with relatively small
|
|
|
|
|
|
group sizes. [#2625]
|
|
|
|
|
|
- Allow row-oriented data input using a new ``rows`` keyword argument.
|
|
|
|
|
|
[#850]
|
|
|
|
|
|
- Allow subclassing of ``Table`` and the component classes ``Row``, ``Column``,
|
|
|
|
|
|
``MaskedColumn``, ``TableColumns``, and ``TableFormatter``. [#2287]
|
|
|
|
|
|
- Fix to allow numpy integer types as valid indices into tables in
|
|
|
|
|
|
Python 3.x [#2477]
|
|
|
|
|
|
- Remove transition code related to the order change in ``Column`` and
|
|
|
|
|
|
``MaskedColumn`` arguments ``name`` and ``data`` from Astropy 0.2
|
|
|
|
|
|
to 0.3. [#2511]
|
|
|
|
|
|
- Change HTML table representation in IPython notebook to show all
|
|
|
|
|
|
table columns instead of restricting to 80 column width. [#2651]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- Mean and apparent sidereal time can now be calculated using the
|
|
|
|
|
|
``sidereal_time`` method [#1418].
|
|
|
|
|
|
- The time scale now defaults to UTC if no scale is provided. [#2091]
|
|
|
|
|
|
- ``TimeDelta`` objects can have all scales but UTC, as well as, for
|
|
|
|
|
|
consistency with time-like quantities, undefined scale (where the
|
|
|
|
|
|
scale is taken from the object one adds to or subtracts from).
|
|
|
|
|
|
This allows, e.g., to work consistently in TDB. [#1932]
|
|
|
|
|
|
- ``Time`` now supports ISO format strings that end in "Z". [#2211, #2203]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- Support for the unit format `Office of Guest Investigator Programs (OGIP)
|
|
|
|
|
|
FITS files
|
|
|
|
|
|
<http://heasarc.gsfc.nasa.gov/docs/heasarc/ofwg/docs/general/ogip_93_001/>`__
|
|
|
|
|
|
has been added. [#377]
|
|
|
|
|
|
- The ``spectral`` equivalency can now handle angular wave number. [#1306 and
|
|
|
|
|
|
#1899]
|
|
|
|
|
|
- Added ``one`` as a shorthand for ``dimensionless_unscaled``. [#1980]
|
|
|
|
|
|
- Added ``dex`` and ``dB`` units. [#1628]
|
|
|
|
|
|
- Added ``temperature()`` equivalencies to support conversion between
|
|
|
|
|
|
Kelvin, Celsius, and Fahrenheit. [#2209]
|
|
|
|
|
|
- Added ``temperature_energy()`` equivalencies to support conversion
|
|
|
|
|
|
between electron-volt and Kelvin. [#2637]
|
|
|
|
|
|
- The runtime of ``astropy.units.Unit.compose`` is greatly improved
|
|
|
|
|
|
(by a factor of 2 in most cases) [#2544]
|
|
|
|
|
|
- Added ``electron`` unit. [#2599]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- ``timer.RunTimePredictor`` now uses ``astropy.modeling`` in its
|
|
|
|
|
|
``do_fit()`` method. [#1896]
|
|
|
|
|
|
- ``astropy.vo``
|
|
|
|
|
|
- A new sub-package, ``astropy.vo.samp``, is now available (this was
|
|
|
|
|
|
previously the SAMPy package, which has been refactored for use in
|
|
|
|
|
|
Astropy). [#1907]
|
|
|
|
|
|
- Enhanced functionalities for ``VOSCatalog`` and ``VOSDatabase``. [#1206]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- astropy now requires wcslib version 4.23 or later. The version of
|
|
|
|
|
|
wcslib included with astropy has been updated to version 4.23.
|
|
|
|
|
|
- Bounds checking is now performed on native spherical
|
|
|
|
|
|
coordinates. Any out-of-bounds values will be returned as
|
|
|
|
|
|
``NaN``, and marked in the ``stat`` array, if using the
|
|
|
|
|
|
low-level ``wcslib`` interface such as
|
|
|
|
|
|
``astropy.wcs.Wcsprm.p2s``. [#2107]
|
|
|
|
|
|
- A new method, ``astropy.wcs.WCS.compare()``, compares two wcsprm
|
|
|
|
|
|
structs for equality with varying degrees of strictness. [#2361]
|
|
|
|
|
|
- New ``astropy.wcs.utils`` module, with a handful of tools for manipulating
|
|
|
|
|
|
WCS objects, including dropping, swapping, and adding axes.
|
|
|
|
|
|
- Misc
|
|
|
|
|
|
- Includes the new astropy-helpers package which separates some of Astropy's
|
|
|
|
|
|
build, installation, and documentation infrastructure out into an
|
|
|
|
|
|
independent package, making it easier for Affiliated Packages to depend on
|
|
|
|
|
|
these features. astropy-helpers replaces/deprecates some of the submodules
|
|
|
|
|
|
in the ``astropy`` package (see API Changes below). See also
|
|
|
|
|
|
`APE 4 <https://github.com/astropy/astropy-APEs/blob/master/APE4.rst>`_

|
|
|
|
|

|
* API Changes
|
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
|
- The configuration system received a major overhaul, as part of APE3. It is
|
|
|
|
|
|
no longer possible to save configuration items from Python, but instead
|
|
|
|
|
|
users must edit the configuration file directly. The locations of
|
|
|
|
|
|
configuration items have moved, and some have been changed to science state
|
|
|
|
|
|
values. The old locations should continue to work until astropy 0.5, but
|
|
|
|
|
|
deprecation warnings will be displayed. See the `Configuration transition
|
|
|
|
|
|
<http://astropy.readthedocs.org/en/v0.4/config/config_0_4_transition.html>`_
|
|
|
|
|
|
docs for a detailed description of the changes and how to update existing
|
|
|
|
|
|
code. [#2094]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- The ``astropy.io.fits.new_table`` function is now fully deprecated (though
|
|
|
|
|
|
will not be removed for a long time, considering how widely it is used).
|
|
|
|
|
|
Instead please use the more explicit ``BinTableHDU.from_columns`` to create
|
|
|
|
|
|
a new binary table HDU, and the similar ``TableHDU.from_columns`` to create
|
|
|
|
|
|
a new ASCII table. These otherwise accept the same arguments as
|
|
|
|
|
|
``new_table`` which is now just a wrapper for these.
|
|
|
|
|
|
- The ``.fromstring`` classmethod of each HDU type has been simplified such
|
|
|
|
|
|
that, true to its namesake, it only initializes an HDU from a string
|
|
|
|
|
|
containing its header *and* data.
|
|
|
|
|
|
- Fixed an issue where header wildcard matching (for example
|
|
|
|
|
|
``header['DATE*']``) can be used to match *any* characters that might
|
|
|
|
|
|
appear in a keyword. Previously this only matched keywords containing
|
|
|
|
|
|
characters in the set ``[0-9A-Za-z_]``. Now this can also match a hyphen
|
|
|
|
|
|
``-`` and any other characters, as some conventions like ``HIERARCH`` and
|
|
|
|
|
|
record-valued keyword cards allow a wider range of valid characters than
|
|
|
|
|
|
standard FITS keywords.
|
|
|
|
|
|
- This will be the *last* release to support the following APIs that have
|
|
|
|
|
|
been marked deprecated since Astropy v0.1/PyFITS v3.1:
|
|
|
|
|
|
- The ``CardList`` class, which was part of the old header implementation.
|
|
|
|
|
|
- The ``Card.key`` attribute. Use ``Card.keyword`` instead.
|
|
|
|
|
|
- The ``Card.cardimage`` and ``Card.ascardimage`` attributes. Use simply
|
|
|
|
|
|
``Card.image`` or ``str(card)`` instead.
|
|
|
|
|
|
- The ``create_card`` factory function. Simply use the normal ``Card``
|
|
|
|
|
|
constructor instead.
|
|
|
|
|
|
- The ``create_card_from_string`` factory function. Use ``Card.fromstring``
|
|
|
|
|
|
instead.
|
|
|
|
|
|
- The ``upper_key`` function. Use ``Card.normalize_keyword`` method
|
|
|
|
|
|
instead (this is not unlikely to be used outside of PyFITS itself, but it
|
|
|
|
|
|
was technically public API).
|
|
|
|
|
|
- The usage of ``Header.update`` with ``Header.update(keyword, value,
|
|
|
|
|
|
comment)`` arguments. ``Header.update`` should only be used analogously
|
|
|
|
|
|
to ``dict.update``. Use ``Header.set`` instead.
|
|
|
|
|
|
- The ``Header.ascard`` attribute. Use ``Header.cards`` instead for a list
|
|
|
|
|
|
of all the ``Card`` objects in the header.
|
|
|
|
|
|
- The ``Header.rename_key`` method. Use ``Header.rename_keyword`` instead.
|
|
|
|
|
|
- The ``Header.get_history`` method. Use ``header['HISTORY']`` instead
|
|
|
|
|
|
(normal keyword lookup).
|
|
|
|
|
|
- The ``Header.get_comment`` method. Use ``header['COMMENT']`` instead.
|
|
|
|
|
|
- The ``Header.toTxtFile`` method. Use ``header.totextfile`` instead.
|
|
|
|
|
|
- The ``Header.fromTxtFile`` method. Use ``Header.fromtextfile`` instead.
|
|
|
|
|
|
- The ``tdump`` and ``tcreate`` functions. Use ``tabledump`` and
|
|
|
|
|
|
``tableload`` respectively.
|
|
|
|
|
|
- The ``BinTableHDU.tdump`` and ``tcreate`` methods. Use
|
|
|
|
|
|
``BinTableHDU.dump`` and ``BinTableHDU.load`` respectively.
|
|
|
|
|
|
- The ``txtfile`` argument to the ``Header`` constructor. Use
|
|
|
|
|
|
``Header.fromfile`` instead.
|
|
|
|
|
|
- The ``startColumn`` and ``endColumn`` arguments to the ``FITS_record``
|
|
|
|
|
|
constructor. These are unlikely to be used by any user code.
|
|
|
|
|
|
These deprecated interfaces will be removed from the development version of
|
|
|
|
|
|
Astropy following the v0.4 release (they will still be available in any
|
|
|
|
|
|
v0.4.x bugfix releases, however).
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- The method computing the derivative of the model with respect
|
|
|
|
|
|
to parameters was renamed from ``deriv`` to ``fit_deriv``. [#1739]
|
|
|
|
|
|
- ``ParametricModel`` and the associated ``Parametric1DModel`` and
|
|
|
|
|
|
``Parametric2DModel`` classes have been renamed ``FittableModel``,
|
|
|
|
|
|
``Fittable1DModel``, and ``Fittable2DModel`` respectively. The base
|
|
|
|
|
|
``Model`` class has subsumed the functionality of the old
|
|
|
|
|
|
``ParametricModel`` class so that all models support parameter constraints.
|
|
|
|
|
|
The only distinction of ``FittableModel`` is that anything which subclasses
|
|
|
|
|
|
it is assumed "safe" to use with Astropy fitters. [#2276]
|
|
|
|
|
|
- ``NonLinearLSQFitter`` has been renamed ``LevMarLSQFitter`` to emphasise
|
|
|
|
|
|
that it uses the Levenberg-Marquardt optimization algorithm with a
|
|
|
|
|
|
least squares statistic function. [#1914]
|
|
|
|
|
|
- The ``SLSQPFitter`` class has been renamed ``SLSQPLSQFitter`` to emphasize
|
|
|
|
|
|
that it uses the Sequential Least Squares Programming optimization
|
|
|
|
|
|
algorithm with a least squares statistic function. [#1914]
|
|
|
|
|
|
- The ``Fitter.errorfunc`` method has been renamed to the more general
|
|
|
|
|
|
``Fitter.objective_function``. [#1914]
|
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
|
- Issue warning if unit is changed from a non-trivial value by directly
|
|
|
|
|
|
setting ``NDData.unit``. [#2411]
|
|
|
|
|
|
- The ``mask`` and ``flag`` attributes of ``astropy.nddata.NDData`` can now
|
|
|
|
|
|
be set with any array-like object instead of requiring that they be set
|
|
|
|
|
|
with a ``numpy.ndarray``. [#2419]
|
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
|
- Use of the ``astropy.sphinx`` module is deprecated; all new development of
|
|
|
|
|
|
this module is in ``astropy_helpers.sphinx`` which should be used instead
|
|
|
|
|
|
(therefore documentation builds that made use of any of the utilities in
|
|
|
|
|
|
``astropy.sphinx`` now have ``astropy_helpers`` as a documentation
|
|
|
|
|
|
dependency).
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- The default table printing function now shows a table header row for units
|
|
|
|
|
|
if any columns have the unit attribute set. [#1282]
|
|
|
|
|
|
- Before, an unmasked ``Table`` was automatically converted to a masked
|
|
|
|
|
|
table if generated from a masked Table or a ``MaskedColumn``.
|
|
|
|
|
|
Now, this conversion is only done if explicitly requested or if any
|
|
|
|
|
|
of the input values is actually masked. [#1185]
|
|
|
|
|
|
- The repr() function of ``astropy.table.Table`` now shows the units
|
|
|
|
|
|
if any columns have the unit attribute set. [#2180]
|
|
|
|
|
|
- The semantics of the config options ``table.max_lines`` and
|
|
|
|
|
|
``table.max_width`` has changed slightly. If these values are not
|
|
|
|
|
|
set in the config file, astropy will try to determine the size
|
|
|
|
|
|
automatically from the terminal. [#2683]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- Correct use of UT in TDB calculation [#1938, #1939].
|
|
|
|
|
|
- ``TimeDelta`` objects can have scales other than TAI [#1932].
|
|
|
|
|
|
- Location information should now be passed on via an ``EarthLocation``
|
|
|
|
|
|
instance or anything that initialises it, e.g., a tuple containing
|
|
|
|
|
|
either geocentric or geodetic coordinates. [#1928]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- ``Quantity`` now converts input to float by default, as this is physically
|
|
|
|
|
|
most sensible for nearly all units [#1776].
|
|
|
|
|
|
- ``Quantity`` comparisons with ``==`` or ``!=`` now always return ``True``
|
|
|
|
|
|
or ``False``, even if units do not match (for which case a ``UnitsError``
|
|
|
|
|
|
used to be raised). [#2328]
|
|
|
|
|
|
- Applying ``float`` or ``int`` to a ``Quantity`` now works for all
|
|
|
|
|
|
dimensionless quantities; they are automatically converted to unscaled
|
|
|
|
|
|
dimensionless. [#2249]
|
|
|
|
|
|
- The exception ``astropy.units.UnitException``, which was
|
|
|
|
|
|
deprecated in astropy 0.2, has been removed. Use
|
|
|
|
|
|
``astropy.units.UnitError`` instead [#2386]
|
|
|
|
|
|
- Initializing a ``Quantity`` with a valid number/array with a ``unit``
|
|
|
|
|
|
attribute now interprets that attribute as the units of the input value.
|
|
|
|
|
|
This makes it possible to initialize a ``Quantity`` from an Astropy
|
|
|
|
|
|
``Table`` column and have it correctly pick up the units from the column.
|
|
|
|
|
|
[#2486]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- ``calcFootprint`` was deprecated. It is replaced by
|
|
|
|
|
|
``calc_footprint``. An optional boolean keyword ``center`` was
|
|
|
|
|
|
added to ``calc_footprint``. It controls whether the centers or
|
|
|
|
|
|
the corners of the pixels are used in the computation. [#2384]
|
|
|
|
|
|
- ``astropy.wcs.WCS.sip_pix2foc`` and
|
|
|
|
|
|
``astropy.wcs.WCS.sip_foc2pix`` formerly did not conform to the
|
|
|
|
|
|
``SIP`` standard: ``CRPIX`` was added to the ``foc`` result so
|
|
|
|
|
|
that it could be used as input to "core FITS WCS". As of astropy
|
|
|
|
|
|
0.4, ``CRPIX`` is no longer added to the result, so the ``foc``
|
|
|
|
|
|
space is correct as defined in the `SIP convention
|
|
|
|
|
|
<http://adsabs.harvard.edu/abs/2005ASPC..347..491S>`__. [#2360]
|
|
|
|
|
|
- ``astropy.wcs.UnitConverter``, which was deprecated in astropy
|
|
|
|
|
|
0.2, has been removed. Use the ``astropy.units`` module
|
|
|
|
|
|
instead. [#2386]
|
|
|
|
|
|
- The following methods on ``astropy.wcs.WCS``, which were
|
|
|
|
|
|
deprecated in astropy 0.1, have been removed [#2386]:
|
|
|
|
|
|
- ``all_pix2sky`` -> ``all_pix2world``
|
|
|
|
|
|
- ``wcs_pix2sky`` -> ``wcs_pix2world``
|
|
|
|
|
|
- ``wcs_sky2pix`` -> ``wcs_world2pix``
|
|
|
|
|
|
- The ``naxis1`` and ``naxis2`` attributes and the ``get_naxis``
|
|
|
|
|
|
method of ``astropy.wcs.WCS``, which were deprecated in astropy
|
|
|
|
|
|
0.2, have been removed. Use the shape of the underlying FITS data
|
|
|
|
|
|
array instead. [#2386]
|
|
|
|
|
|
- Misc
|
|
|
|
|
|
- The ``astropy.setup_helpers`` and ``astropy.version_helpers`` modules are
|
|
|
|
|
|
deprecated; any non-critical fixes and development to those modules should
|
|
|
|
|
|
be in ``astropy_helpers`` instead. Packages that use these modules in
|
|
|
|
|
|
their ``setup.py`` should depend on ``astropy_helpers`` following the same
|
|
|
|
|
|
pattern as in the Astropy package template.
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
- ``astropy.constants``
|
|
|
|
|
|
- ``astropy.constants.Contant`` objects can now be deep
|
|
|
|
|
|
copied. [#2601]
|
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
|
- The distance modulus function in ``astropy.cosmology`` can now handle
|
|
|
|
|
|
negative distances, which can occur in certain closed cosmologies. [#2008]
|
|
|
|
|
|
- Removed accidental imports of some extraneous variables in
|
|
|
|
|
|
``astropy.cosmology`` [#2025]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- ``astropy.io.ascii.read`` would fail to read lists of strings where some of
|
|
|
|
|
|
the strings consisted of just a newline ("\n"). [#2648]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- Use NaN for missing values in FITS when using Table.write for float
|
|
|
|
|
|
columns. Earlier the default fill value was close to 1e20.[#2186]
|
|
|
|
|
|
- Fixes for checksums on 32-bit platforms. Results may be different
|
|
|
|
|
|
if writing or checking checksums in "nonstandard" mode. [#2484]
|
|
|
|
|
|
- Additional minor bug fixes ported from PyFITS. [#2575]
|
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
|
- It is now possible to save an ``astropy.table.Table`` object as a
|
|
|
|
|
|
VOTable with any of the supported data formats, ``tabledata``,
|
|
|
|
|
|
``binary`` and ``binary2``, by using the ``tabledata_format``
|
|
|
|
|
|
kwarg. [#2138]
|
|
|
|
|
|
- Fixed a crash writing out variable length arrays. [#2577]
|
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
|
- Indexing ``NDData`` in a way that results in a single element returns that
|
|
|
|
|
|
element. [#2170]
|
|
|
|
|
|
- Change construction of result of arithmetic and unit conversion to allow
|
|
|
|
|
|
subclasses to require the presence of attribute like unit. [#2300]
|
|
|
|
|
|
- Scale uncertainties to correct units in arithmetic operations and unit
|
|
|
|
|
|
conversion. [#2393]
|
|
|
|
|
|
- Ensure uncertainty and mask members are copied in arithmetic and
|
|
|
|
|
|
convert_unit_to. [#2394]
|
|
|
|
|
|
- Mask result of arithmetic if either of the operands is masked. [#2403]
|
|
|
|
|
|
- Copy all attributes of input object if ``astropy.nddata.NDData`` is
|
|
|
|
|
|
initialized with an ``NDData`` object. [#2406]
|
|
|
|
|
|
- Copy ``flags`` to new object in ``convert_unit_to``. [#2409]
|
|
|
|
|
|
- Result of ``NDData`` arithmetic makes a copy of any WCS instead of using
|
|
|
|
|
|
a reference. [#2410]
|
|
|
|
|
|
- Fix unit handling for multiplication/division and use
|
|
|
|
|
|
``astropy.units.Quantity`` for units arithmetic. [#2413]
|
|
|
|
|
|
- A masked ``NDData`` is now converted to a masked array when used in an
|
|
|
|
|
|
operation or ufunc with a numpy array. [#2414]
|
|
|
|
|
|
- An unmasked ``NDData`` now uses an internal representation of its mask
|
|
|
|
|
|
state that ``numpy.ma`` expects so that an ``NDData`` behaves as an
|
|
|
|
|
|
unmasked array. [#2417]
|
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
|
- Fix crash in smart resolver when the resolution doesn't work. [#2591]
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- The ``astropy.table.Column`` object can now use both functions and callable
|
|
|
|
|
|
objects as formats. [#2313]
|
|
|
|
|
|
- Fixed a problem on 64 bit windows that caused errors
|
|
|
|
|
|
"expected 'DTYPE_t' but got 'long long'" [#2490]
|
|
|
|
|
|
- Fix initialisation of ``TableColumns`` with lists or tuples. [#2647]
|
|
|
|
|
|
- Fix removal of single column using ``remove_columns``. [#2699]
|
|
|
|
|
|
- Fix a problem that setting a row element within a masked table did not
|
|
|
|
|
|
update the corresponding table element. [#2734]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- Correct UT1->UTC->UT1 round-trip being off by 1 second if UT1 is
|
|
|
|
|
|
on a leap second. [#2077]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- ``Quantity.copy`` now behaves identically to ``ndarray.copy``, and thus
|
|
|
|
|
|
supports the ``order`` argument (for numpy >=1.6). [#2284]
|
|
|
|
|
|
- Composing base units into identical composite units now works. [#2382]
|
|
|
|
|
|
- Creating and composing/decomposing units is now substantially faster [#2544]
|
|
|
|
|
|
- ``Quantity`` objects now are able to be assigned NaN [#2695]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- Astropy now requires wcslib version 4.23 or later. The version of
|
|
|
|
|
|
wcslib included with astropy has been updated to version 4.23.
|
|
|
|
|
|
- Bug fixes in the projection routines: in ``hpxx2s`` [the
|
|
|
|
|
|
cartesian-to-spherical operation of the ``HPX`` projection]
|
|
|
|
|
|
relating to bounds checking, bug introduced at wcslib 4.20; in
|
|
|
|
|
|
``parx2s`` and molx2s`` [the cartesion-to-spherical operation of
|
|
|
|
|
|
the ``PAR`` and ``MOL`` projections respectively] relating to
|
|
|
|
|
|
setting the stat vector; in ``hpxx2s`` relating to implementation
|
|
|
|
|
|
of the vector API; and in ``xphx2s`` relating to setting an
|
|
|
|
|
|
out-of-bounds value of *phi*.
|
|
|
|
|
|
- In the ``PCO`` projection, use alternative projection equations
|
|
|
|
|
|
for greater numerical precision near theta == 0. In the ``COP``
|
|
|
|
|
|
projection, return an exact result for theta at the poles.
|
|
|
|
|
|
Relaxed the tolerance for bounds checking a little in ``SFL``
|
|
|
|
|
|
projection.
|
|
|
|
|
|
- Fix a bug allocating insufficient memory in
|
|
|
|
|
|
``astropy.wcs.WCS.sub`` [#2468]
|
|
|
|
|
|
- A new method, ``Wcsprm.bounds_check`` (corresponding to wcslib's
|
|
|
|
|
|
``wcsbchk``) has been added to control what bounds checking is performed by
|
|
|
|
|
|
wcslib.
|
|
|
|
|
|
- ``WCS.to_header`` will now raise a more meaningful exception when the WCS
|
|
|
|
|
|
information is invalid or inconsistent in some way. [#1854]
|
|
|
|
|
|
- In ``WCS.to_header``, ``RESTFRQ`` and ``RESTWAV`` are no longer
|
|
|
|
|
|
rewritten if zero. [#2468]
|
|
|
|
|
|
- In ``WCS.to_header``, floating point values will now always be written
|
|
|
|
|
|
with an exponent or fractional part, i.e. ``.0`` being appended if necessary
|
|
|
|
|
|
to acheive this. [#2468]
|
|
|
|
|
|
- If the C extension for ``astropy.wcs`` was not built or fails to import for
|
|
|
|
|
|
any reason, ``import astropy.wcs`` will result in an ``ImportError``,
|
|
|
|
|
|
rather than getting obscure errors once the ``astropy.wcs`` is used.
|
|
|
|
|
|
[#2061]
|
|
|
|
|
|
- When the C extension for ``astropy.wcs`` is built using a version of
|
|
|
|
|
|
``wscslib`` already present in the system, the package does not try
|
|
|
|
|
|
to install ``wcslib`` headers under ``astropy/wcs/include``. [#2536]
|
|
|
|
|
|
- Fixes an unresolved external symbol error in the
|
|
|
|
|
|
`astropy.wcs._wcs` C extension on Microsoft Windows when built
|
|
|
|
|
|
with a Microsoft compiler. [#2478]
|
|
|
|
|
|
- Misc
|
|
|
|
|
|
- Running the test suite with ``python setup.py test`` now works if
|
|
|
|
|
|
the path to the source contains spaces. [#2488]
|
|
|
|
|
|
- The version of ERFA included with Astropy is now v1.1.0 [#2497]
|
|
|
|
|
|
- Removed deprecated option from travis configuration and force use of
|
|
|
|
|
|
wheels rather than allowing build from source. [#2576]
|
|
|
|
|
|
- The short option ``-n`` to run tests in parallel was broken
|
|
|
|
|
|
(conflicts with the distutils built-in option of "dry-run").
|
|
|
|
|
|
Changed to ``-j``. [#2566]
|
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
|
- ``python setup.py test --coverage`` will now give more accurate
|
|
|
|
|
|
results, because the coverage analysis will include early imports of
|
|
|
|
|
|
astropy. There doesn't seem to be a way to get this to work when
|
|
|
|
|
|
doing ``import astropy; astropy.test()``, so the ``coverage``
|
|
|
|
|
|
keyword to ``astropy.test`` has been removed. Coverage testing now
|
|
|
|
|
|
depends only on `coverage.py
|
|
|
|
|
|
<http://nedbatchelder.com/code/coverage/>`__, not
|
|
|
|
|
|
``pytest-cov``. [#2112]
|
|
|
|
|
|
- The included version of py.test has been upgraded to 2.5.1. [#1970]
|
|
|
|
|
|
- The included version of six.py has been upgraded to 1.5.2. [#2006]
|
|
|
|
|
|
- Where appropriate, tests are now run both with and without the
|
|
|
|
|
|
``unicode_literals`` option to ensure that we support both cases. [#1962]
|
|
|
|
|
|
- Running the Astropy test suite from within the IPython REPL is disabled for
|
|
|
|
|
|
now due to bad interaction between the test runner and IPython's logging
|
|
|
|
|
|
and I/O handler. For now, run the Astropy tests should be run in the basic
|
|
|
|
|
|
Python interpreter. [#2684]
|
|
|
|
|
|
- Added support for numerical comparison of floating point values appearing in
|
|
|
|
|
|
the output of doctests using a ``+FLOAT_CMP`` doctest flag. [#2087]
|
|
|
|
|
|
- A monkey patch is performed to fix a bug in Numpy version 1.7 and
|
|
|
|
|
|
earlier where unicode fill values on masked arrays are not
|
|
|
|
|
|
supported. This may cause unintended side effects if your
|
|
|
|
|
|
application also monkey patches ``numpy.ma`` or relies on the broken
|
|
|
|
|
|
behavior. If unicode support of masked arrays is important to your
|
|
|
|
|
|
application, upgrade to Numpy 1.8 or later for best results. [#2059]
|
|
|
|
|
|
- The developer documentation has been extensively rearranged and
|
|
|
|
|
|
rewritten. [#1712]
|
|
|
|
|
|
- The ``human_time`` function in ``astropy.utils`` now returns strings
|
|
|
|
|
|
without zero padding. [#2420]
|
|
|
|
|
|
- The ``bdist_dmg`` command for ``setup.py`` has now been removed. [#2553]
|
|
|
|
|
|
- Many broken API links have been fixed in the documentation, and the
|
|
|
|
|
|
``nitpick`` Sphinx option is now used to avoid broken links in future.

* Bug Fixes
|
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
|
- if ``sep`` argument is specified to be a single character in
|
|
|
|
|
|
``sexagisimal_to_string``, it now includes seperators only between
|
|
|
|
|
|
items [#2183]
|
|
|
|
|
|
- Ensure comparisons involving ``Distance`` objects do not raise exceptions;
|
|
|
|
|
|
also ensure operations that lead to units other than length return
|
|
|
|
|
|
``Quantity``. [#2206, #2250]
|
|
|
|
|
|
- Multiplication and division of ``Angle`` objects is now
|
|
|
|
|
|
supported. [#2273]
|
|
|
|
|
|
- Fixed ``Angle.to_string`` functionality so that negative angles have the
|
|
|
|
|
|
correct amount of padding when ``pad=True``. [#2337]
|
|
|
|
|
|
- Mixing strings and quantities in the ``Angle`` constructor now
|
|
|
|
|
|
works. For example: ``Angle(['1d', 1. * u.d])``. [#2398]
|
|
|
|
|
|
- If ``Longitude`` is given a ``Longitude`` as input, use its ``wrap_angle``
|
|
|
|
|
|
by default [#2705]
|
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
|
- Fixed ``format()`` compatibility with Python 2.6. [#2129]
|
|
|
|
|
|
- Be more careful about converting to floating point internally [#1815, #1818]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- The CDS reader in ``astropy.io.ascii`` can now handle multiple
|
|
|
|
|
|
description lines in ReadMe files. [#2225]
|
|
|
|
|
|
- When reading a table with values that generate an overflow error during
|
|
|
|
|
|
type conversion (e.g. overflowing the native C long type), fall through to
|
|
|
|
|
|
using string. Previously this generated an exception [#2234].
|
|
|
|
|
|
- Some CDS files mark missing values with ``"---"``, others with ``"--"``.
|
|
|
|
|
|
Recognize any string with one to four dashes as null value. [#1335]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- Allow pickling of ``FITS_rec`` objects. [#1597]
|
|
|
|
|
|
- Improved behavior when writing large compressed images on OSX by removing
|
|
|
|
|
|
an unncessary check for platform architecture. [#2345]
|
|
|
|
|
|
- Fixed an issue where Astropy ``Table`` objects containing boolean columns
|
|
|
|
|
|
were not correctly written out to FITS files. [#1953]
|
|
|
|
|
|
- Several other bug fixes ported from PyFITS v3.2.3 [#2368]
|
|
|
|
|
|
- Fixed a crash on Python 2.x when writing a FITS file directly to a
|
|
|
|
|
|
``StringIO.StringIO`` object. [#2463]
|
|
|
|
|
|
- ``astropy.io.registry``
|
|
|
|
|
|
- Allow readers/writers with the same name to be attached to different
|
|
|
|
|
|
classes. [#2312]
|
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
|
- By default, floating point values are now written out using
|
|
|
|
|
|
``repr`` rather than ``str`` to preserve precision [#2137]
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- Fixed the ``SIP`` and ``InverseSIP`` models both so that they work in the
|
|
|
|
|
|
first place, and so that they return results consistent with the SIP
|
|
|
|
|
|
functions in ``astropy.wcs``. [#2177]
|
|
|
|
|
|
- ``astropy.stats``
|
|
|
|
|
|
- Ensure the ``axis`` keyword in ``astropy.stats.funcs`` can now be used for
|
|
|
|
|
|
all axes. [#2173]
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- Ensure nameless columns can be printed, using 'None' for the header. [#2213]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- Fixed pickling of ``Time`` objects. [#2123]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- ``Quantity._repr_latex_()`` returns ``NotImplementedError`` for quantity
|
|
|
|
|
|
arrays instead of an uninformative formatting exception. [#2258]
|
|
|
|
|
|
- Ensure ``Quantity.flat`` always returns ``Quantity``. [#2251]
|
|
|
|
|
|
- Angstrom unit renders better in MathJax [#2286]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- Progress bars will now be displayed inside the IPython
|
|
|
|
|
|
qtconsole. [#2230]
|
|
|
|
|
|
- ``data.download_file()`` now evaluates ``REMOTE_TIMEOUT()`` at runtime
|
|
|
|
|
|
rather than import time. Previously, setting ``REMOTE_TIMEOUT`` after
|
|
|
|
|
|
import had no effect on the function's behavior. [#2302]
|
|
|
|
|
|
- Progressbar will be limited to 100% so that the bar does not exceed the
|
|
|
|
|
|
terminal width. The numerical display can still exceed 100%, however.
|
|
|
|
|
|
- ``astropy.vo``
|
|
|
|
|
|
- Fixed ``format()`` compatibility with Python 2.6. [#2129]
|
|
|
|
|
|
- Cone Search validation no longer raises ``ConeSearchError`` for positive RA.
|
|
|
|
|
|
[#2240, #2242]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- Fixed a bug where calling ``astropy.wcs.Wcsprm.sub`` with
|
|
|
|
|
|
``WCSSUB_CELESTIAL`` may cause memory corruption due to
|
|
|
|
|
|
underallocation of a temporary buffer. [#2350]
|
|
|
|
|
|
- Fixed a memory allocation bug in ``astropy.wcs.Wcsprm.sub`` and
|
|
|
|
|
|
``astropy.wcs.Wcsprm.copy``. [#2439]
|
|
|
|
|
|
- Misc
|
|
|
|
|
|
- Fixes for compatibility with Python 3.4. [#1945]
|
|
|
|
|
|
- ``import astropy; astropy.test()`` now correctly uses the same test
|
|
|
|
|
|
configuration as ``python setup.py test`` [#1811]
|
|
|
|
|
|
- Update to 0.3.1 (2014-03-04)
|
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
|
- Fixed a bug where ``ConfigurationItem.set_temp()`` does not reset to
|
|
|
|
|
|
default value when exception is raised within ``with`` block. [#2117]
|
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|
|
- Fixed a bug where ``_truncation`` was left undefined for ``CustomKernel``.
|
|
|
|
|
|
[#2016]
|
|
|
|
|
|
- Fixed a bug with ``_normalization`` when ``CustomKernel`` input array
|
|
|
|
|
|
sums to zero. [#2016]
|
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
|
- Fixed a bug where using ``==`` on two array coordinates wouldn't
|
|
|
|
|
|
work. [#1832]
|
|
|
|
|
|
- Fixed bug which caused ``len()`` not to work for coordinate objects and
|
|
|
|
|
|
added a ``.shape`` property to get appropriately array-like behavior.
|
|
|
|
|
|
[#1761, #2014]
|
|
|
|
|
|
- Fixed a bug where sexagesimal notation would sometimes include
|
|
|
|
|
|
exponential notation in the last field. [#1908, #1913]
|
|
|
|
|
|
- ``CompositeStaticMatrixTransform`` no longer attempts to reference the
|
|
|
|
|
|
undefined variable ``self.matrix`` during instantiation. [#1944]
|
|
|
|
|
|
- Fixed pickling of ``Longitude``, ensuring ``wrap_angle`` is preserved
|
|
|
|
|
|
[#1961]
|
|
|
|
|
|
- Allow ``sep`` argument in ``Angle.to_string`` to be empty (resulting in no
|
|
|
|
|
|
separators) [#1989]
|
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
|
- Allow passing unicode delimiters when reading or writing tables. The
|
|
|
|
|
|
delimiter must be convertible to pure ASCII. [#1949]
|
|
|
|
|
|
- Fix a problem when reading a table and renaming the columns to names that
|
|
|
|
|
|
already exist. [#1991]
|
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
|
- Ported all bug fixes from PyFITS 3.2.1. See the PyFITS changelog at
|
|
|
|
|
|
http://pyfits.readthedocs.org/en/v3.2.1/ [#2056]
|
|
|
|
|
|
- ``astropy.io.misc``
|
|
|
|
|
|
- Fixed issues in the HDF5 Table reader/writer functions that occurred on
|
|
|
|
|
|
Windows. [#2099]
|
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
|
- The ``write_null_values`` kwarg to ``VOTable.to_xml``, when set to `False`
|
|
|
|
|
|
(the default) would produce non-standard VOTable files. Therefore, this
|
|
|
|
|
|
functionality has been replaced by a better understanding that knows which
|
|
|
|
|
|
fields in a VOTable may be left empty (only ``char``, ``float`` and
|
|
|
|
|
|
``double`` in VOTable 1.1 and 1.2, and all fields in VOTable 1.3). The
|
|
|
|
|
|
kwarg is still accepted but it will be ignored, and a warning is emitted.
|
|
|
|
|
|
[#1809]
|
|
|
|
|
|
- Printing out a ``astropy.io.votable.tree.Table`` object using `repr` or
|
|
|
|
|
|
`str` now uses the pretty formatting in ``astropy.table``, so it's possible
|
|
|
|
|
|
to easily preview the contents of a ``VOTable``. [#1766]
|
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
|
- Fixed bug in computation of model derivatives in ``LinearLSQFitter``.
|
|
|
|
|
|
[#1903]
|
|
|
|
|
|
- Raise a ``NotImplementedError`` when fitting composite models. [#1915]
|
|
|
|
|
|
- Fixed bug in the computation of the ``Gaussian2D`` model. [#2038]
|
|
|
|
|
|
- Fixed bug in the computation of the ``AiryDisk2D`` model. [#2093]
|
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
|
- Added slightly more useful debug info for AstropyAutosummary. [#2024]
|
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
|
- The column string representation for n-dimensional cells with only
|
|
|
|
|
|
one element has been fixed. [#1522]
|
|
|
|
|
|
- Fix a problem that caused ``MaskedColumn.__getitem__`` to not preserve
|
|
|
|
|
|
column metadata. [#1471, #1872]
|
|
|
|
|
|
- With Numpy prior to version 1.6.2, tables with Unicode columns now
|
|
|
|
|
|
sort correctly. [#1867]
|
|
|
|
|
|
- ``astropy.table`` can now print out tables with Unicode columns containing
|
|
|
|
|
|
non-ascii characters. [#1864]
|
|
|
|
|
|
- Columns can now be named with Unicode strings, as long as they contain only
|
|
|
|
|
|
ascii characters. This makes using ``astropy.table`` easier on Python 2
|
|
|
|
|
|
when ``from __future__ import unicode_literals`` is used. [#1864]
|
|
|
|
|
|
- Allow pickling of ``Table``, ``Column``, and ``MaskedColumn`` objects. [#792]
|
|
|
|
|
|
- Fix a problem where it was not possible to rename columns after sorting or
|
|
|
|
|
|
adding a row. [#2039]
|
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
|
- Fix a problem where scale conversion problem in TimeFromEpoch
|
|
|
|
|
|
was not showing a useful error [#2046]
|
|
|
|
|
|
- Fix a problem when converting to one of the formats ``unix``, ``cxcsec``,
|
|
|
|
|
|
``gps`` or ``plot_date`` when the time scale is ``UT1``, ``TDB`` or ``TCB``
|
|
|
|
|
|
[#1732]
|
|
|
|
|
|
- Ensure that ``delta_ut1_utc`` gets calculated when accessed directly,
|
|
|
|
|
|
instead of failing and giving a rather obscure error message [#1925]
|
|
|
|
|
|
- Fix a bug when computing the TDB to TT offset. The transform routine was
|
|
|
|
|
|
using meters instead of kilometers for the Earth vector. [#1929]
|
|
|
|
|
|
- Increase ``__array_priority__`` so that ``TimeDelta`` can convert itself
|
|
|
|
|
|
to a ``Quantity`` also in reverse operations [#1940]
|
|
|
|
|
|
- Correct hop list from TCG to TDB to ensure that conversion is
|
|
|
|
|
|
possible [#2074]
|
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
|
- ``Quantity`` initialisation rewritten for speed [#1775]
|
|
|
|
|
|
- Fixed minor string formatting issue for dimensionless quantities. [#1772]
|
|
|
|
|
|
- Fix error for inplace operations on non-contiguous quantities [#1834].
|
|
|
|
|
|
- The definition of the unit ``bar`` has been corrected to "1e5
|
|
|
|
|
|
Pascal" from "100 Pascal" [#1910]
|
|
|
|
|
|
- For units that are close to known units, but not quite, for
|
|
|
|
|
|
example due to differences in case, the exception will now include
|
|
|
|
|
|
recommendations. [#1870]
|
|
|
|
|
|
- The generic and FITS unit parsers now accept multiple slashes in
|
|
|
|
|
|
the unit string. There are multiple ways to interpret them, but
|
|
|
|
|
|
the approach taken here is to convert "m/s/kg" to "m s-1 kg-1".
|
|
|
|
|
|
Multiple slashes are accepted, but discouraged, by the FITS
|
|
|
|
|
|
standard, due to the ambiguity of parsing, so a warning is raised
|
|
|
|
|
|
when it is encountered. [#1911]
|
|
|
|
|
|
- The use of "angstrom" (with a lower case "a") is now accepted in FITS unit
|
|
|
|
|
|
strings, since it is in common usage. However, since it is not officially
|
|
|
|
|
|
part of the FITS standard, a warning will be issued when it is encountered.
|
|
|
|
|
|
[#1911]
|
|
|
|
|
|
- Pickling unrecognized units will not raise a ``AttributeError``. [#2047]
|
|
|
|
|
|
- ``astropy.units`` now correctly preserves the precision of
|
|
|
|
|
|
fractional powers. [#2070]
|
|
|
|
|
|
- If a ``Unit`` or ``Quantity`` is raised to a floating point power
|
|
|
|
|
|
that is very close to a rational number with a denominator less
|
|
|
|
|
|
than or equal to 10, it is converted to a ``Fraction`` object to
|
|
|
|
|
|
preserve its precision through complex unit conversion operations.
|
|
|
|
|
|
[#2070]
|
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
|
- Fixed crash in ``timer.RunTimePredictor.do_fit``. [#1905]
|
|
|
|
|
|
- Fixed ``astropy.utils.compat.argparse`` for Python 3.1. [#2017]
|
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
|
- ``astropy.wcs.WCS``, ``astropy.wcs.WCS.fix`` and
|
|
|
|
|
|
``astropy.wcs.find_all_wcs`` now have a ``translate_units`` keyword
|
|
|
|
|
|
argument that is passed down to ``astropy.wcs.Wcsprm.fix``. This can be
|
|
|
|
|
|
used to specify any unsafe translations of units from rarely used ones to
|
|
|
|
|
|
more commonly used ones.
|
|
|
|
|
|
Although ``"S"`` is commonly used to represent seconds, its translation to
|
|
|
|
|
|
``"s"`` is potentially unsafe since the standard recognizes ``"S"``
|
|
|
|
|
|
formally as Siemens, however rarely that may be used. The same applies to
|
|
|
|
|
|
``"H"`` for hours (Henry), and ``"D"`` for days (Debye).
|
|
|
|
|
|
When these sorts of changes are performed, a warning is emitted.
|
|
|
|
|
|
[#1854]
|
|
|
|
|
|
- When a unit is "fixed" by ``astropy.wcs.WCS.fix`` or
|
|
|
|
|
|
``astropy.wcs.Wcsprm.unitfix``, it now correctly reports the ``CUNIT``
|
|
|
|
|
|
field that was changed. [#1854]
|
|
|
|
|
|
- ``astropy.wcs.Wcs.printwcs`` will no longer warn that ``cdelt`` is being
|
|
|
|
|
|
ignored when none was present in the FITS file. [#1845]
|
|
|
|
|
|
- ``astropy.wcs.Wcsprm.set`` is called from within the ``astropy.wcs.WCS``
|
|
|
|
|
|
constructor, therefore any invalid information in the keywords will be
|
|
|
|
|
|
raised from the constructor, rather than on a subsequent call to a
|
|
|
|
|
|
transformation method. [#1918]
|
|
|
|
|
|
- Fix a memory corruption bug when using ``astropy.wcs.Wcs.sub`` with
|
|
|

* Other Changes and Additions
|
|
|
|
|
|
- A new function, ``astropy.wcs.get_include``, has been added to get the
|
|
|
|
|
|
location of the ``astropy.wcs`` C header files. [#1755]
|
|
|
|
|
|
- The doctests in the ``.rst`` files in the ``docs`` folder are now
|
|
|
|
|
|
tested along with the other unit tests. This is in addition to the
|
|
|
|
|
|
testing of doctests in docstrings that was already being performed.
|
|
|
|
|
|
See ``docs/development/testguide.rst`` for more information. [#1771]
