# API Changes
|
||
## astropy.wcs
|
||
* The pixel argument to
|
||
astropy.visualization.wcsaxes.ticklabels.TickLabels.add no
|
||
longer does anything, is deprecated, and will be removed in a
|
||
future astropy version. It has been replaced by a new required
|
||
data argument, which should be used to specify the data
|
||
coordinates of the tick label being added.
|
||
* This changes has been made because it is (in general) not
|
||
possible to correctly calculate pixel coordinates before
|
||
Matplotlib is drawing a figure. [#12630]
|
||
# Bug Fixes
|
||
## astropy.coordinates
|
||
* Fixed a bug that prevented SkyOffsetFrame instances to be
|
||
pickled by adding a custom __reduce__ method to the class (see
|
||
issue #9249). [#13305]
|
||
* Fixed the check for invalid Latitude values for float32 values.
|
||
Latitude now accepts the float32 value of pi/2, which was
|
||
rejected before because a comparison was made using the
|
||
slightly smaller float64 representation. See issue #13708.
|
||
[#13745]
|
||
## astropy.io.ascii
|
||
* Fixed confusing chained exception messages of read() function
|
||
when it fails. [#13170]
|
||
* When writing out a :class:`~astropy.table.Table` to HTML
|
||
format, the formats keyword argument to the
|
||
:meth:`~astropy.table.Table.write` method will now be applied.
|
||
[#13453]
|
||
## astropy.io.fits
|
||
* heapsize is now checked for VLA tables. An error is thrown
|
||
whether P format is used but the heap size is bigger than what
|
||
can be indexed with a 32 bit signed int. [#13429]
|
||
* Fix parsing of ascii TFORM when precision is missing. [#13520]
|
||
* A compressed image HDU created from the header of a PRIMARY
|
||
HDU, now correctly updates 'XTENSION' and 'SIMPLE' keywords.
|
||
[#13557]
|
||
* Empty variable-length arrays are now properly handled when
|
||
pathological combinations of heapoffset and heapsize are
|
||
encountered. [#13621]
|
||
* PCOUNT and GCOUNT keywords are now removed from an uncompressed
|
||
Primary header, for compliancy with fitsverify behavior.
|
||
[#13753]
|
||
## astropy.modeling
|
||
* Bugfix for using MagUnit units on model parameters. [#13158]
|
||
* Fix bug in using non-linear fitters to fit 0-degree polynomials
|
||
using weights. [#13628]
|
||
## astropy.table
|
||
* Fix a problem where accessing one field of a structured column
|
||
returned a Column with the same info as the original column.
|
||
This resulted in unintuitive behavior in general and an
|
||
exception if the format for the column was set. [#13269]
|
||
* Tables with columns with structured data can now be properly
|
||
stacked and joined. [#13306]
|
||
* Update jQuery to 3.6.0, to pick up security fixes. [#13438]
|
||
* Fix a Python 3.11 compatibility issue. Ensure that when
|
||
removing a table column that the pprint_include_names or
|
||
pprint_exclude_names attributes get updated correctly. [#13639]
|
||
* When using add_columns with same indexes in indexes option or
|
||
without specifying the option, the order of the new columns
|
||
will now be kept. [#13783]
|
||
* Fix a bug when printing or getting the representation of a
|
||
multidimensional table column that has a zero dimension.
|
||
[#13838]
|
||
* Ensure that mixin columns and their info are not shared between
|
||
tables even when their underlying data is shared with
|
||
copy=False. [#13842]
|
||
## astropy.time
|
||
* Fix Time.insert() on times which have their out_subfmt set.
|
||
[#12732]
|
||
* Prevent Time() from being initialized with an invalid precision
|
||
leading to incorrect results when representing the time as a
|
||
string. [#13068]
|
||
* Fix a bug in Time where a date string like "2022-08-01.123" was
|
||
being parsed as an ISO-format time "2022-08-01 00:00:00.123".
|
||
The fractional part at the end of the string was being taken as
|
||
seconds. Now this raises an exception because the string is not
|
||
in ISO format. [#13731]
|
||
## astropy.units
|
||
* Significantly improved the performance of parsing composite
|
||
units with the FITS format, by ensuring the detailed_exception
|
||
argument is properly passed on and thus used. [#12699]
|
||
* Ensure that np.concatenate on quantities can take a dtype
|
||
argument (added in numpy 1.20). [#13323]
|
||
* Ensure that the units of any initial argument to reductions
|
||
such as np.add.reduce (which underlies np.sum) are properly
|
||
taken into account. [#13340]
|
||
## astropy.utils
|
||
* Ensure that np.concatenate on masked data can take a dtype
|
||
argument (added in numpy 1.20). [#13323]
|
||
* Fix error when suppressing download progress bar while using
|
||
non-default sys.stdout stream. [#13352]
|
||
* Ensure str and repr work properly for Masked versions of
|
||
structured subarrays. [#13404]
|
||
* If an attribute is created using deprecated_attribute() with
|
||
the alternative argument then getting or setting the value of
|
||
the deprecated attribute now accesses its replacement. [#13824]
|
||
## astropy.visualization
|
||
* Fixed calling .tight_layout() on a WCSAxes. [#12418]
|
||
## astropy.wcs
|
||
* WCS.pixel_to_world now creates an EarthLocation object using
|
||
MJD-AVG if present before falling back to the old behaviour of
|
||
using MJD-OBS. [#12598]
|
||
* The locations of WCSAxes ticks and tick-labels are now
|
||
correctly calculated when the DPI of a figure changes between a
|
||
WCSAxes being created and the figure being drawn, or when a
|
||
rasterized artist is added to the WCSAxes. [#12630]
|
||
* Fix a bug where SlicedLowLevelWCS.world_to_pixel_values would
|
||
break when the result of the transform is dependent on the
|
||
coordinate of a sliced out pixel. [#13579]
|
||
* Updated bundled WCSLIB version to 7.12. This update includes
|
||
bug fixes to wcssub() in how it handles temporal axes with -TAB
|
||
and fixes handling of status returns from linp2x() and linx2p()
|
||
relating to distortion functions, in particular affecting TPV
|
||
distortions - see #13509. For a full list of changes - see
|
||
http://www.atnf.csiro.au/people/mcalabre/WCS/CHANGES or
|
||
astropy/cextern/wcslib/CHANGES. [#13635]
|
||
* Fixed WCS validation not working properly if HDUList is needed
|
||
for multi-extension FITS file. [#13668]

# 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

||
(when building --without system_wcslib)
|
||
- Release 5.0.3
|
||
# 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]

Sun Mar 13 08:10:02 UTC 2022 - Ben Greiner <code@bnavigator.de>
|
||
|
||
- 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]

||
* Trying to create an instance of astropy.coordinates.Distance by
|
||
providing both z and parallax now raises the expected
|
||
ValueError. [#12531]
|
||
* Fixed a bug where changing the wrap angle of the longitude
|
||
component of a representation could raise a warning or error in
|
||
certain situations. [#12556]
|
||
* astropy.coordinates.Distance constructor no longer ignores the
|
||
unit keyword when parallax is provided. [#12569]
|
||
astropy.cosmology
|
||
* astropy.cosmology.utils.aszarr can now convert Column objects.
|
||
[#12525]
|
||
* Reading a cosmology from an ECSV will load redshift and Hubble
|
||
parameter units from the cosmology units module. [#12636]
|
||
astropy.io.fits
|
||
* Fix formatting issue in _dump_coldefs and add tests for
|
||
tabledump and tableload convenience functions. [#12526]
|
||
astropy.io.misc
|
||
* YAML can now also represent quantities and arrays with
|
||
structured dtype, as well as structured scalars based on
|
||
np.void. [#12509]
|
||
astropy.modeling
|
||
* Fixes error when fitting multiplication or division based
|
||
compound models where the sub-models have different output
|
||
units. [#12475]
|
||
* Bugfix for incorrectly initialized and filled parameters data
|
||
for Spline1D model. [#12523]
|
||
* Bugfix for keyerror thrown by Model.input_units_equivalencies
|
||
when used on fix_inputs models which have no set unit
|
||
equivalencies. [#12597]
|
||
astropy.table
|
||
* astropy.table.Table.keep_columns() and
|
||
astropy.table.Table.remove_columns() now work with generators
|
||
of column names. [#12529]
|
||
* Avoid duplicate storage of info in serialized columns if the
|
||
column used to serialize already can hold that information.
|
||
[#12607] astropy.timeseries
|
||
* Fixed edge case bugs which emerged when using
|
||
aggregate_downsample with custom bins. [#12527]
|
||
astropy.units
|
||
* Structured units can be serialized to/from yaml. [#12492]
|
||
* Fix bad typing problems by removing interaction with
|
||
NDArray.__class_getitem__. [#12511]
|
||
* Ensure that Quantity.to_string(format='latex') properly
|
||
typesets exponents also when
|
||
u.quantity.conf.latex_array_threshold = -1 (i.e., when the
|
||
threshold is taken from numpy). [#12573]
|
||
* Structured units can now be copied with copy.copy and
|
||
copy.deepcopy and also pickled and unpicked also for protocol
|
||
>= 2. This does not work for big-endian architecture with older
|
||
numpy<1.21.1. [#12583]
|
||
astropy.utils
|
||
* Ensure that a Masked instance can be used to initialize (or
|
||
viewed as) a numpy.ma.Maskedarray. [#12482]
|
||
* Ensure Masked also works with numpy >=1.22, which has a keyword
|
||
argument name change for np.quantile. [#12511]
|
||
* astropy.utils.iers.LeapSeconds.auto_open() no longer emits
|
||
unnecessary warnings when astropy.utils.iers.conf.auto_max_age
|
||
is set to None. [#12713]

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
|
||

|
||
* 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]

|
||
|
||
- Update to version 4.2.1
|
||
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]
|
||

Thu Oct 15 12:22:54 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to 4.0.3
|
||
* astropy.table

Sat Oct 10 20:46:40 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- 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
|
||
Fix id URL in baseframe-1.0.0 ASDF schema. [#10223]
|
||
Write keys to ASDF only if the value is present, to account for
|
||
a change in behavior in asdf 2.8. [#10674]
|
||
* astropy.io.registry
|
||
Fix Table.(read|write).help when reader or writer has no
|
||
docstring. [#10460]
|
||
* 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
|
||
will be ignored." [#10192]
|
||
* astropy.modeling
|
||
Fixed a problem with mapping input_units and return_units of a
|
||
CompoundModel to the units of the constituent models. [#10158]
|
||
Removed hard-coded names of inputs and outputs. [#10174]
|
||
Fixed a problem where slicing a CompoundModel by name will
|
||
crash if there fix_inputs operators are present. [#10224]
|
||
Removed a limitation of fitting of data with units with
|
||
compound models without units when the expression involves
|
||
operators other than addition and subtraction. [#10415]
|
||
Fixed a problem with fitting Linear1D and Planar2D in model
|
||
sets. [#10623]
|
||
Fixed reported module name of math_functions model classes.
|
||
[#10694]
|
||
Fixed reported module name of tabular model classes. [#10709]
|
||
Do not create new math_functions models for ufuncs that are
|
||
only aliases (divide and mod). [#10697]
|
||
Fix calculation of the Moffat2D derivative with respect to
|
||
gamma. [#10784]
|
||
* astropy.stats
|
||
Fixed an API regression where SigmaClip.__call__ would convert
|
||
masked elements to nan and upcast the dtype to float64 in its
|
||
output MaskedArray when using the axis parameter along with the
|
||
defaults masked=True and copy=True. [#10610]
|
||
Fixed an issue where fully masked MaskedArray input to
|
||
sigma_clipped_stats gave incorrect results. [#10099]
|
||
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
|
||
N with interval='kraft-burrows-nousek' would throw an error
|
||
with mpmath backend. [#10427]
|
||
Fixed bug in funcs.poisson_conf_interval with interval='kraft-
|
||
burrows-nousek' where certain combinations of source and
|
||
background count numbers led to ValueError due to the choice of
|
||
starting value for numerical optimization. [#10618]
|
||
* astropy.table
|
||
Fixed a bug when writing a table with mixin columns to FITS,
|
||
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
|
||
(ra), the column (ra) would be dropped when reading the table
|
||
back. [#10222]
|
||
Fixed a bug when sorting an indexed table on the indexed column
|
||
after first sorting on another column. [#10103]
|
||
Fixed a bug in table argsort when called with reverse=True for
|
||
an indexed table. [#10103]
|
||
Fixed a performance regression introduced in #9048 when
|
||
initializing a table from Python lists. Also fixed incorrect
|
||
behavior (for data types other than float) when those lists
|
||
contain np.ma.masked elements to indicate masked data. [#10636]
|
||
Avoid modifying .meta when serializing columns to FITS.
|
||
[#10485]
|
||
Avoid crash when reading a FITS table that contains mixin info
|
||
and PyYAML is missing. [#10485]
|
||
* astropy.time
|
||
Ensure that for size-1 array Time, the location also properly
|
||
becomes a scalar when indexed with 0. [#10113]
|
||
* astropy.units
|
||
Refined test_parallax to resolve difference between 2012 and
|
||
2015 definitions. [#10569]
|
||
* astropy.utils
|
||
The default IERS server has been updated to use the FTPS server
|
||
hosted by CDDIS. [#9964]
|
||
Fixed memory allocation on 64-bit systems within xml.iterparse
|
||
[#10076]
|
||
Fix case where None could be used in a numerical computation.
|
||
[#10126]
|
||
* astropy.visualization
|
||
Fixed a bug where the ImageNormalize clip keyword was ignored
|
||
when used with calling the object on data. [#10098]
|
||
Fixed a bug where axes.xlabel/axes.ylabel where not correctly
|
||
set nor returned on an EllipticalFrame class WCSAxes plot.
|
||
[#10446]
|
||
* astropy.wcs
|
||
Handled WCS 360 -> 0 deg crossover in fit_wcs_from_points
|
||
[#10155]
|
||
Do not issue DATREF warning when MJDREF has default value.
|
||
[#10440]
|
||
Fixed a bug due to which naxis argument was ignored if header
|
||
was supplied during the initialization of a WCS object.
|
||
[#10532]
|
||
Other Changes and Additions
|
||
* Improved the speed of sorting a large Table on a single column
|
||
by a factor of around 5. [#10103]
|
||
* Ensure that astropy can be used inside Application bundles
|
||
built with pyinstaller. [#8795]
|
||
* Updated the bundled CFITSIO library to 3.49. See cextern/
|

|
||
[gh#astropy/astropy#9918]

|
||
[gh#astropy/astropy#9923]
|
||
Fixed a segmentation fault in the ``fast_reader`` C parsers when parsing an
|
||
invalid file with ``guess=True`` and the file contains inconsistent column
|

|
||
domain and window values.
|
||
[gh#astropy/astropy#9950]
|
||
Fixed a bug which affected overwriting tables within ``hdf5`` files.
|
||
Overwriting an existing path with associated column meta data now also
|
||

|
||
[gh#astropy/astropy#9983]
|
||
Fixed serialization of Time objects with location under time-1.0.0
|
||
ASDF schema.

[gh#astropy/astropy#9711, gh#astropy/astropy#9934]
|
||
Fix regression with ``GroupsHDU`` which needs to modify the header to handle
|
||
invalid headers, and fix accesing ``.data`` for empty HDU.
|
||
[gh#astropy/astropy#9711]
|
||
Fix ``fitsdiff`` when its arguments are directories that contain other
|
||
directories.

||
Fix writing noncontiguous data to a compressed HDU.
|
||
[gh#astropy/astropy#9978]

||
Prevent instantiation of ``PrimaryHDU`` and ``ImageHDU`` with a scalar.
|
||
[gh#astropy/astropy#10069]

|
||
from ASCII tables where not properly converted when accessed by attribute
|
||
name.
|
||
* astropy.io.misc
|
||
[gh#astropy/astropy#9933]

|
||
domain and window values.
|
||
[gh#astropy/astropy#9950]
|
||
Fixed a bug which affected overwriting tables within ``hdf5`` files.
|
||
Overwriting an existing path with associated column meta data now also
|
||
overwrites the meta data associated with the table.
|
||
[gh#astropy/astropy#9983]
|
||
Fixed serialization of Time objects with location under time-1.0.0
|
||
ASDF schema.
|
||

* astropy.table
|
||
[gh#astropy/astropy#9839]
|
||
Fixed bug in ``Table.reverse`` for tables that contain non-mutable mixin columns
|
||
(like ``SkyCoord``) for which in-place item update is not allowed.
|
||
[gh#astropy/astropy#9933]
|
||
Tables containing Magnitude, decibel, and dex columns can now be saved to
|
||
``ecsv`` files.
|
||
[gh#astropy/astropy#10027]
|
||
Fixed bug where adding or inserting a row fails on a table with an index
|
||
defined on a column that is not the first one.
|
||
[gh#astropy/astropy#10068]
|
||
Ensured that ``table.show_in_browser`` also worked for mixin columns like
|
||
``Time`` and ``SkyCoord``.
|
||
* astropy.time
|
||
[gh#astropy/astropy#9679]
|
||
Fix inaccuracy when converting between TimeDelta and datetime.timedelta.

||
Fixed exception when changing ``format`` in the case when ``out_subfmt`` is
|
||
defined and is incompatible with the new format.
|
||
[gh#astropy/astropy#9812]
|
||
Fixed exceptions in ``Time.to_value()``: when supplying any ``subfmt`` argument
|
||
for string-based formats like 'iso', and for ``subfmt='long'`` for the formats
|
||
'byear', 'jyear', and 'decimalyear'.
|
||
[gh#astropy/astropy#9969]
|
||
Fixed bug where the location attribute was lost when creating a new ``Time``
|
||
object from an existing ``Time`` or list of ``Time`` objects.
|
||
[gh#astropy/astropy#10034]
|
||
Fixed a bug where an exception occurred when creating a ``Time`` object
|
||
if the ``val1`` argument was a regular double and the ``val2`` argument
|
||
was a ``longdouble``.
|
||
* astropy.timeseries
|
||
[gh#astropy/astropy#10013]
|
||
Fixed issue with reference time for the ``transit_time`` parameter returned by
|
||
the ``BoxLeastSquares`` periodogram. Now, the ``transit_time`` will be within
|
||
the range of the input data and arbitrary time offsets/zero points no longer
|
||
affect results.
|
||
* astropy.units
|
||
[gh#astropy/astropy#9948]
|
||
Fix for ``quantity_input`` annotation raising an exception on iterable
|
||
types that don't define a general ``__contains__`` for checking if ``None``
|
||
is contained (e.g. Enum as of python3.8), by instead checking for instance of
|
||
Sequence.
|
||
[gh#astropy/astropy#10066]
|
||
Fix for ``u.Quantity`` not taking into account ``ndmin`` if constructed from
|
||
another ``u.Quantity`` instance with different but convertible unit
|
||
* astropy.utils
|
||
[gh#astropy/astropy#9981]
|
||
Fixed ``deprecated_renamed_argument`` not passing in user value to
|
||
deprecated keyword when the keyword has no new name.
|
||
[gh#astropy/astropy#9985]
|
||
Fixed ``deprecated_renamed_argument`` not issuing a deprecation warning when
|
||
deprecated keyword without new name is passed in as positional argument.
|
||
[gh#astropy/astropy#10007]
|
||
Fixed detection of read-only filesystems in the caching code.
|
||
* astropy.visualization
|
||
[gh#astropy/astropy#9848]
|
||
Fixed bug from matplotlib >=3.1 where an empty Quantity array is
|
||
sent for unit conversion as an empty list.
|
||
[gh#astropy/astropy#9913]
|
||
Fix bug in ``ZScaleInterval`` to return the array minimum and
|
||
maximum when there are less then ``min_npixels`` in the input array.
|
||
[gh#astropy/astropy#8004, gh#astropy/astropy#9991]
|
||
Fix a bug in simplifying axis labels that affected non-rectangular frames.
|
||

- 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.
|
||
+ API Changes
|
||
> astropy.constants
|
||
* Deprecated ``set_enabled_constants`` context manager. Use
|
||
``astropy.physical_constants`` and ``astropy.astronomical_constants``.
|
||
|
||
> astropy.convolution
|
||
* Removed the deprecated keyword argument ``interpolate_nan`` from
|
||
``convolve_fft``.
|
||
* Removed the deprecated keyword argument ``stddev`` from
|
||
``Gaussian2DKernel``.
|
||
* Deprecated and renamed ``MexicanHat1DKernel`` and ``MexicanHat2DKernel``
|
||
to ``RickerWavelet1DKernel`` and ``RickerWavelet2DKernel``.
|
||
> 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.
|
||
> astropy.extern
|
||
* Remove the bundled ``six`` module.
|
||
> astropy.io.ascii
|
||
* Masked column handling has changed, see ``astropy.table`` entry below.
|
||
|
||
> astropy.io.misc
|
||
* 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.
|
||
+ Bug Fixes
|
||
> astropy.coordinates
|
||
* 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
|
||
to set, e.g., ``representation_type``, or refer to the class by its fully
|
||
qualified name).
|
||
> astropy.io.fits
|
||
* Implemented skip (after warning) of header cards with reserved
|
||
keywords in ``table_to_hdu``.
|
||
* Add ``AstropyDeprecationWarning`` to ``read_table_fits`` when ``hdu=`` is
|
||
selected, but does not match single present table HDU.
|
||
> astropy.io.votable
|
||
* Ignore BINARY2 null mask bits for string values
|
||
on parsing a VOTable. In this way, the reader should never create masked
|
||
values for string types.
|
||
* Corrected a spurious warning issued for the ``value`` attribute of the
|
||
``<OPTION>`` element in VOTable, as well as a test that erroneously
|
||
treated the warning as acceptable.
|
||
> astropy.nddata
|
||
* ``Cutout2D`` will now get the WCS from its first argument if that argument
|
||
has with WCS property.
|
||
* ``overlap_slices`` will now raise a ``ValueError`` if the input
|
||
position contains any non-finite values (e.g. NaN or inf).
|
||
> astropy.stats
|
||
* Fixed a bug where ``bayesian_blocks`` returned a single edge.
|
||
* Fixed input data type validation for ``bayesian_blocks`` to work int
|
||
arrays.
|
||
> astropy.table
|
||
* Fix bug where adding a column consisting of a list of masked arrays was
|
||
dropping the masks.
|
||
* ``Quantity`` columns with custom units can now round-trip via FITS tables,
|
||
as long as the custom unit is enabled during reading (otherwise, the unit
|
||
will become an ``UnrecognizedUnit``).
|
||
* Fix bug where string values could be truncated when inserting into a
|
||
``Column`` or ``MaskedColumn``, or when adding or inserting a row containing
|
||
string values.
|
||
> astropy.time
|
||
* Fix bug when ``Time`` object is created with only masked elements.
|
||
* Fix inaccuracy when converting between TimeDelta and datetime.timedelta.
|
||
|
||
> astropy.units
|
||
* Ensure that output from test functions of and comparisons between quantities
|
||
can be stored into pre-allocated output arrays (using ``out=array``)
|
||
> astropy.utils
|
||
* 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.
|
||
> astropy.visualization
|
||
* 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.

accepts time in TT.
|
||
* astropy.io.ascii
|

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

||
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).

|
||
+ 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 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.

-------------------------------------------------------------------
|
||
Thu Jan 28 13:14:55 UTC 2016 - toddrme2178@gmail.com
|
||
|
||
- 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 the Thomson scattering cross-section. [#3839]
|
||
- ``astropy.convolution``
|
||
- 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]
|
||
- Update to 1.0.5
|
||
+ Bug Fixes
|
||
* ``astropy.constants``
|
||
> Rename units -> unit and error -> uncertainty in the ``repr`` and ``str``
|
||
of constants to match attribute names. [#4147]
|
||
* ``astropy.coordinates``
|
||
> Fix string representation of ``SkyCoord`` objects transformed into
|
||
the ``AltAz`` frame [#4055]
|
||
|
||
> Fix the ``search_around_sky`` function to allow ``storekdtree`` to be
|
||
``False`` as was intended. [#4082]
|
||
* ``astropy.io.fits``
|
||
> Fix bug when extending one header (without comments) with another
|
||
(with comments). [#3967]
|
||
> 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]
|
||
> Fix bug where reading a file without a newline failed with an
|
||
unrelated / unhelpful exception. [#4160]
|
||
* ``astropy.modeling``
|
||
> Cleaned up ``repr`` of models that have no parameters. [#4076]
|
||
* ``astropy.nddata``
|
||
> Initializing ``NDDataArray`` from another instance now sets ``flags`` as
|
||
expected and no longer fails when ``uncertainty`` is set [#4129].
|
||
Initializing an ``NDData`` subclass from a parent instance
|
||
(eg. ``NDDataArray`` from ``NDData``) now sets the attributes other than
|
||
``data`` as it should [#4137].
|
||
* ``astropy.table``
|
||
> Fix bug when doing outer join on multi-dimensional columns. [#4060]
|
||
> Fix an issue with setting fill value when column dtype is changed. [#4088]
|
||
> Fix bug when unpickling a bare Column where the _parent_table
|
||
attribute was not set. This impacted the Column representation. [#4099]
|
||
> Fix issue with the web browser opening with an empty page, and ensure that
|
||
the url is correctly formatted for Windows. [#4132]
|
||
> Fix NameError in table stack exception message. [#4213]
|
||
* ``astropy.utils``
|
||
> ``resolve_name`` no longer causes ``sys.modules`` to be cluttered with
|
||
additional copies of modules under a package imported like
|
||
``resolve_name('numpy')``. [#4084]
|
||
> ``console`` was updated to support IPython 4.x and Jupyter 1.x.
|
||
This should supress a ShimWarning that was appearing at
|
||
import of astropy with IPython 4.0 or later. [#4078]
|
||
> Temporary downloaded files created by ``get_readable_fileobj`` when passed
|
||
a URL are now deleted immediately after the file is closed. [#4198]
|
||
* ``astropy.visualization``
|
||
> The color for axes labels was set to white. Since white labels on white
|
||
background are hard to read, the label color has been changed to black.
|
||
[#4143]
|
||
> ``ImageNormalize`` now automatically determines ``vmin``/``vmax``
|
||
(via the ``autoscale_None`` method) when they have not been set
|
||
explicitly. [#4117]
|
||
* ``astropy.vo``
|
||
> Cone Search validation no longer crashes when the provider gives an
|
||
incomplete test query. It also ensures search radius for a test query
|
||
is not too large to avoid timeout. [#4158, #4159]
|
||
+ 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
|
||
yields a new object in UnitSphericalRepresentation [#3938]
|
||
* ``astropy.cosmology``
|
||
> Fixed wCDM to not ignore the Ob0 parameter on initialization. [#3934]
|
||
* ``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]
|
||
