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

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

|
|
|
|
|
|
- update to version 1.1.1
|
|
|
|
|
+ New Features
|
|
|
|
|
- ``astropy.io.registry``
|
|
|
|
|
* Allow ``pathlib.Path`` objects (available in Python 3.4 and later) for
|
|
|
|
|
specifying the file name in registry read / write functions. [#4405]
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
* ``console.human_file_size`` now accepts quantities with byte-equivalent
|
|
|
|
|
units [#4373]
|
|
|
|
|
+ Bug Fixes
|
|
|
|
|
- ``astropy.analytic_functions``
|
|
|
|
|
* Fixed the blackbody functions' handling of overflows on some platforms
|
|
|
|
|
(Windows with MSVC, older Linux versions) with a buggy ``expm1`` function.
|
|
|
|
|
[#4393]
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
* Fixed an bug where updates to string columns in FITS tables were not saved
|
|
|
|
|
on Python 3. [#4452]
|
|
|
|
|
+ Other Changes and Additions
|
|
|
|
|
- Updated bundled astropy-helpers to v1.1.1. [#4413]
|
|
|
|
|
- update to version 1.1
|
|
|
|
|
+ New Features
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
- Added new tools ``set_temp_config`` and ``set_temp_cache`` which can be
|
|
|
|
|
used either as function decorators or context managers to temporarily
|
|
|
|
|
use alternative directories in which to read/write the Astropy config
|
|
|
|
|
files and download caches respectively. This is especially useful for
|
|
|
|
|
testing, though ``set_temp_cache`` may also be used as a way to provide
|
|
|
|
|
an alternative (application specific) download cache for large data files,
|
|
|
|
|
rather than relying on the default cache location in users' home
|
|
|
|
|
directories. [#3975]
|
|
|
|
|
- ``astropy.constants``
|
|
|
|
|
- Added the Thomson scattering cross-section. [#3839]
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|

|
|
|
|
|
- ``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]
|
|
|
|
|

|
|
|
|
|
- ``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``
|
|
|

|
|
|
|
|
- ``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]
|
|
|
|
|

|
|
|
|
|
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]
|
|
|
|
|
* ``astropy.modeling``
|
|
|
|
|
> Added missing default values for ``Ellipse2D`` parameters. [#3903]
|
|
|
|
|
> Improved support for pickling of compound models, including both compound
|
|
|
|
|
model instances, and new compound model classes. [#3867]
|
|
|
|
|
* ``astropy.table``
|
|
|
|
|
> Added missing default values for ``Ellipse2D`` parameters. [#3903]
|
|
|
|
|
* ``astropy.time``
|
|
|
|
|
> Fixed iteration of scalar ``Time`` objects so that ``iter()`` correctly
|
|
|
|
|
raises a ``TypeError`` on them (while still allowing ``Time`` arrays to be
|
|
|
|
|
iterated). [#4048]
|
|
|
|
|
* ``astropy.units``
|
|
|
|
|
> Added frequency-equivalency check when declaring doppler equivalencies
|
|
|
|
|
[#3728]
|
|
|
|
|
> Define ``floor_divide`` (``//``) for ``Quantity`` to be consistent
|
|
|
|
|
``divmod``, such that it only works where the quotient is dimensionless.
|
|
|
|
|
This guarantees that ``(q1 // q2) * q2 + (q1 % q2) == q1``. [#3817]
|
|
|
|
|
> Fixed the documentation of supported units to correctly report support for
|
|
|
|
|
SI prefixes. Previously the table of supported units incorrectly showed
|
|
|
|
|
several derived unit as not supporting prefixes, when in fact they do.
|
|
|
|
|
[#3835]
|
|
|
|
|
> Fix a crash when calling ``astropy.units.cds.enable()``. This will now
|
|
|
|
|
"set" rather than "add" units to the active set to avoid the namespace
|
|
|
|
|
clash with the default units. [#3873]
|
|
|
|
|
> Ensure in-place operations on ``float32`` quantities work. [#4007]
|
|
|
|
|
* ``astropy.utils``
|
|
|
|
|
> The ``deprecated`` decorator did not correctly wrap classes that have a
|
|
|
|
|
custom metaclass--the metaclass could be dropped from the deprecated
|
|
|
|
|
version of the class. [#3997]
|
|
|
|
|
> The ``wraps`` decorator would copy the wrapped function's name to the
|
|
|
|
|
wrapper function even when ``'__name__'`` is excluded from the ``assigned``
|
|
|
|
|
argument. [#4016]
|
|
|
|
|
* Misc
|
|
|
|
|
> ``fitscheck`` no longer causes scaled image data to be rescaled when
|
|
|
|
|
adding checksums to existing files. [#3884]
|
|
|
|
|
> Fixed an issue where running ``import astropy`` from within the source
|
|
|
|
|
tree did not automatically build the extension modules if the source is
|
|
|
|
|
from a source distribution (as opposed to a git repository). [#3932]
|
|
|
|
|
> Fixed multiple instances of a bug that prevented Astropy from being used
|
|
|
|
|
when compiled with the ``python -OO`` flag, due to it causing all
|
|
|
|
|
docstrings to be stripped out. [#3923]
|
|
|
|
|
> Removed source code template files that were being installed
|
|
|
|
|
accidentally alongside installed Python modules. [#4014]
|
|
|
|
|
> Fixed a bug in the exception logging that caused a crash in the exception
|
|
|
|
|
handler itself on Python 3 when exceptions do not include a message.
|

- update to version 1.0.3:
|
|
|
|
|
* New Features
|
|
|
|
|
+ astropy.table
|
|
|
|
|
o Greatly improved the speed of printing a large table to the
|
|
|
|
|
screen when only a few rows are being displayed. [#3796]
|
|
|
|
|
+ astropy.time
|
|
|
|
|
o Add support for the 2015-Jun-30 leap second. [#3794]
|
|
|
|
|
* API Changes
|
|
|
|
|
+ astropy.io.ascii

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

|
|
|
|
|
|
|
- update to version 1.0.2:
|
|
|
|
|
* New Features
|
|
|
|
|
+ "astropy.modeling"
|
|
|
|
|
o Added support for polynomials with degree 0 or degree greater
|
|
|
|
|
than 15. [#3574, 3589]
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
+ "astropy.config"
|
|
|
|
|
o The pre-astropy-0.4 configuration API has been fixed. It was
|
|
|
|
|
inadvertently broken in 1.0.1. [#3627]
|
|
|
|
|
+ "astropy.io.fits"
|
|
|
|
|
o Fixed handling of BINTABLE with TDIMn of size 1. [#3580]
|
|
|
|
|
o Fixed a severe memory leak that occurred when reading tile
|
|
|
|
|
compressed images. [#3680]
|
|
|
|
|
o Fixed bug where column data could be unintentionally
|
|
|
|
|
byte-swapped when copying data from an existing FITS file to a
|
|
|
|
|
new FITS table with a TDIMn keyword for that column. [#3561]
|
|
|
|
|
o The "ColDefs.change_attrib", "ColDefs.change_name", and
|
|
|
|
|
"ColDefs.change_unit" methods now work as advertised. It is
|
|
|
|
|
also possible (and preferable) to update attributes directly
|
|
|
|
|
on "Column" objects (for example setting "column.name"), and
|
|
|
|
|
the change will be accurately reflected in any associated
|
|
|
|
|
table data and its FITS header. [#3283, #1539, #2618]
|
|
|
|
|
o Fixes an issue with the "FITS_rec" interface to FITS table
|
|
|
|
|
data, where a "FITS_rec" created by copying an existing FITS
|
|
|
|
|
table but adding new rows could not be sliced or masked
|
|
|
|
|
correctly. [#3641]
|
|
|
|
|
+ "astropy.io.votable"
|
|
|
|
|
o Loading a "TABLE" element without any "DATA" now correctly
|
|
|
|
|
creates a 0-row array. [#3636]
|
|
|
|
|
+ "astropy.modeling"
|
|
|
|
|
o Added workaround to support inverses on compound models when
|
|
|
|
|
one of the sub-models is itself a compound model with a
|
|
|
|
|
manually-assigned custom inverse. [#3542]
|
|
|
|
|
o Fixed instantiation of polynomial models with constraints for
|
|
|
|
|
parameters (constraints could still be assigned after
|
|
|
|
|
instantiation, but not during). [#3606]
|
|
|
|
|
o Fixed fitting of 2D polynomial models with the
|
|
|
|
|
"LeVMarLSQFitter". [#3606]
|
|
|
|
|
+ "astropy.table"
|
|
|
|
|
o Ensure "QTable" can be pickled [#3590]
|
|
|
|
|
o Some corner cases when instantiating an "astropy.table.Table"
|
|
|
|
|
with a Numpy array are handled [#3637]. Notably:
|
|
|
|
|
o a zero-length array is the same as passing "None"
|
|
|
|
|
o a scalar raises a "ValueError"
|
|
|
|
|
o a one-dimensional array is treated as a single row of a table.
|
|
|
|
|
+ "astropy.time"
|
|
|
|
|
o Ensure a "Column" without units is treated as an "array", not
|
|
|
|
|
as an
|
|
|
|
|
o Ensure a "Column" without units is treated as an "array", not
|
|
|
|
|
as an dimensionless "Quantity". [#3648]
|
|
|
|
|
+ "astropy.units"
|
|
|
|
|
o Ensure equivalencies that do more than just scale a "Quantity"
|
|
|
|
|
are properly handled also in "ufunc" evaluations. [#2496,
|
|
|
|
|
#3586]
|
|
|
|
|
o The LaTeX representation of the Angstrom unit has changed from
|
|
|
|
|
"\overset{\circ}{A}" to "\mathring{A}", which should have
|
|
|
|
|
better support across regular LaTeX, MathJax and matplotlib
|
|
|
|
|
(as of version 1.5) [#3617]
|
|
|
|
|
+ "astropy.vo"
|
|
|
|
|
o Using HTTPS/SSL for communication between SAMP hubs now works
|
|
|
|
|
correctly on all supported versions of Python [#3613]
|
|
|
|
|
+ "astropy.wcs"
|
|
|
|
|
o When no "relax" argument is passed to "WCS.to_header()" and
|
|
|
|
|
the result omits non-standard WCS keywords, a warning is
|
|
|
|
|
emitted. [#3652]
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
+ Nothing changed yet.
|
|
|
|
|
+ "astropy.units"
|
|
|
|
|
o Clarified imperial mass measurements and added pound force
|
|
|
|
|
(lbf), kilopound (kip), and pound per square inch
|
|
|
|
|
(psi). [#3409]
|
|
|
|
|
+ "astropy.vo"
|
|
|
|
|
o The number of retries for connections in "astropy.vo.samp" can
|
|
|
|
|
now be configured by a "n_retries" configuration
|
|
|
|
|
option. [#3612]
|
|
|
|
|
+ Testing
|
|
|
|
|
o Running "astropy.test()" from within the IPython prompt has
|
|
|
|
|
been provisionally re-enabled. [#3184]
|
|
|
|
|
- update to version 1.0.1:
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
- astropy.constants
|
|
|
|
|
+ Ensure constants can be turned into Quantity safely. [#3537, #3538]
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
+ Fix a segfault in the fast C parser when one of the column headers is empty [#3545].
|
|
|
|
|
+ Fixed support for reading inf and nan values with the fast
|
|
|
|
|
reader in Windows. Also fixed in the case of using
|
|
|
|
|
use_fast_converter=True with the fast reader. [#3525]
|
|
|
|
|
+ Fixed use of mmap in the fast reader on Windows. [#3525]
|
|
|
|
|
+ Fixed issue where commented header would treat comments
|
|
|
|
|
defining the table (i.e. column headers) as purely information
|
|
|
|
|
comments, leading to problems when trying to round-trip the
|
|
|
|
|
table. [#3562]
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
+ Fixed propagation of parameter constraints ('fixed', 'bounds',
|
|
|
|
|
'tied') between compound models and their components. There is
|
|
|
|
|
may still be some difficulty defining 'tied' constraints
|
|
|
|
|
properly for use with compound models, however. [#3481]
|
|
|
|
|
- astropy.nddata
|
|
|
|
|
+ Restore several properties to the compatibility class
|
|
|
|
|
NDDataArray that were inadvertently omitted [#3466].
|
|
|
|
|
- astropy.time
|
|
|
|
|
+ Time objects now always evalutate to True, except when
|
|
|
|
|
empty. [#3530]
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
- Updated bundled astropy-helpers version to v1.0.1 to address
|
|
|
|
|
installation issues with some packages that depend on
|
|
|
|
|
Astropy. [#3541]
|
|
|
|
|
* Miscellaneous
|
|
|
|
|
- astropy._erfa
|
|
|
|
|
+ The ERFA wrappers are now written directly in the Python/C API
|
|
|
|
|
rather than using Cython, for greater performance. [#3521]
|
|
|
|
|
- Improve import time of astropy [#3488].
|
|
|
|
|
- specfile: added fits2bitmap binary
|
|
|
|
|
- update to version 1.0:
|
|
|
|
|
* General
|
|
|
|
|
- Astropy now requires a Numpy 1.6.0 or later.
|
|
|
|
|
* New Features
|
|
|
|
|
- astropy.analytic_functions
|
|
|
|
|
+ The astropy.analytic_functions was added to contain analytic
|
|
|
|
|
functions useful for astronomy [#3077].
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
+ astropy.coordinates now has a full stack of frames allowing
|
|
|
|
|
transformations from ICRS or other celestial systems down to
|
|
|
|
|
Alt/Az coordinates. [#3217]
|
|
|
|
|
+ astropy.coordinates now has a get_sun function that gives the
|
|
|
|
|
coordinates of the Sun at a specified time. [#3217]
|
|
|
|
|
+ SkyCoord now has to_pixel and from_pixel methods that convert
|
|
|
|
|
between celestial coordinates as SkyCoord objects and pixel
|
|
|
|
|
coordinates given an astropy.wcs.WCS object. [#3002]
|
|
|
|
|
+ SkyCoord now has search_around_sky and search_around_3d
|
|
|
|
|
convenience methods that allow searching for all coordinates
|
|
|
|
|
within a certain distance of another SkyCoord. [#2953]
|
|
|
|
|
+ SkyCoord can now accept a frame instance for the frame= keyword
|
|
|
|
|
argument. [#3063]
|
|
|
|
|
+ SkyCoord now has a guess_from_table method that can be used to
|
|
|
|
|
quickly create SkyCoord objects from an astropy.table.Table
|
|
|
|
|
object. [#2951]
|
|
|
|
|
+ astropy.coordinates now has a Galactocentric frame, a coordinate
|
|
|
|
|
frame centered on a (user specified) center of the Milky
|
|
|
|
|
Way. [#2761, #3286]
|
|
|
|
|
+ SkyCoord now accepts more formats of the coordinate string when
|
|
|
|
|
the representation has ra and dec attributes. [#2920]
|
|
|
|
|
+ SkyCoord can now accept lists of SkyCoord objects, frame
|
|
|
|
|
objects, or representation objects and will combine them into a
|
|
|
|
|
single object. [#3285]
|
|
|
|
|
+ Frames and SkyCoord instances now have a method
|
|
|
|
|
is_equivalent_frame that can be used to check that two frames
|
|
|
|
|
are equivalent (ignoring the data). [#3330]
|
|
|
|
|
+ The __repr__ of coordinate objects now shows scalar coordinates
|
|
|
|
|
in the same format as vector coordinates. [#3350, 3448]
|
|
|
|
|
- astropy.cosmology
|
|
|
|
|
+ Added lookback_distance, which is c * lookback_time. [#3145]
|
|
|
|
|
+ Add baryonic matter density and dark matter only density
|
|
|
|
|
parameters to cosmology objects [#2757].
|
|
|
|
|
+ Add a clone method to cosmology objects to allow copies of
|
|
|
|
|
cosmological objects to be created with the specified variables
|
|
|
|
|
modified [#2592].
|
|
|
|
|
+ Increase default numerical precision of z_at_value following the
|
|
|
|
|
accurate by default, fast by explicit request model [#3074].
|
|
|
|
|
+ Cosmology functions that take a single (redshift) input now
|
|
|
|
|
broadcast like numpy ufuncs. So, passing an arbitrarily shaped
|
|
|
|
|
array of inputs will produce an output of the same
|
|
|
|
|
shape. [#3178, #3194]
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
+ Simplify the way new Reader classes are defined, allowing custom
|
|
|
|
|
behavior entirely by overriding inherited class attributes
|
|
|
|
|
instead of setting instance attributes in the Reader __init__
|
|
|
|
|
method. [#2812]
|
|
|
|
|
+ There is now a faster C/Cython engine available for reading and
|
|
|
|
|
writing simple ASCII formats like CSV. Both are enabled by
|
|
|
|
|
default, and fast reading will fall back on an ordinary reader
|
|
|
|
|
in case of a parsing failure. Their behavior can be altered with
|
|
|
|
|
the parameter fast_reader in read and fast_writer in
|
|
|
|
|
write. [#2716]
|
|
|
|
|
+ Make Latex/AASTex tables use unit attribute of Column for
|
|
|
|
|
output. [#3064]
|
|
|
|
|
+ Store comment lines encountered during reading in metadata of
|
|
|
|
|
the output table via meta['comment_lines']. [#3222]
|
|
|
|
|
+ Write comment lines in Table metadata during output for all
|
|
|
|
|
basic formats, IPAC, and fast writers. This functionality can be
|
|
|
|
|
disabled with comment=False. [#3255]
|
|
|
|
|
+ Add reader / writer for the Enhanced CSV format which stores
|
|
|
|
|
table and column meta data, in particular data type and
|
|
|
|
|
unit. [#2319]
|
|
|
|
|
+ Automatically use guess=False when reading if the file format is
|
|
|
|
|
provided and the format parameters are uniquely specified. This
|
|
|
|
|
update also removes duplicate format guesses to improve
|
|
|
|
|
performance. [#3418]
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
+ The fitsdiff script ignores some things by default when
|
|
|
|
|
comparing fits files (e.g. empty header lines). This adds a
|
|
|
|
|
--exact option where nothing is ignored. [#2782, #3110]
|
|
|
|
|
+ The fitsheader script now takes a --keyword option to extract a
|
|
|
|
|
specific keyword from the header of a FITS file, and a --table
|
|
|
|
|
option to export headers into any of the data formats supported
|
|
|
|
|
by astropy.table. [#2555, #2588]
|
|
|
|
|
+ Section now supports all advanced indexing features ndarray does
|
|
|
|
|
(slices with any steps, integer arrays, boolean arrays, None,
|
|
|
|
|
Ellipsis). It also properly returns scalars when this is
|
|
|
|
|
appropriate. [#3148]
|
|
|
|
|
- astropy.io.votable
|
|
|
|
|
+ astropy.io.votable.parse now takes a datatype_mapping keyword
|
|
|
|
|
argument to map invalid datatype names to valid ones in order to
|
|
|
|
|
support non-compliant files. [#2675]
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
+ Added the capability of creating new "compound" models by
|
|
|
|
|
combining existing models using arithmetic operators. See the
|
|
|
|
|
"What's New in 1.0" page in the Astropy documentation for more
|
|
|
|
|
details. [#3231]
|
|
|
|
|
+ A new custom_model decorator/factory function has been added for
|
|
|
|
|
converting normal functions to Model classes that can work
|
|
|
|
|
within the Astropy modeling framework. This replaces the old
|
|
|
|
|
custom_model_1d function which is now deprecated. The new
|
|
|
|
|
function works the same as the old one but is less limited in
|
|
|
|
|
the types of models it can be used to created. [#1763]
|
|
|
|
|
+ The Model and Fitter classes have .registry attributes which
|
|
|
|
|
provide sets of all loaded Model and Fitter classes (this is
|
|
|
|
|
useful for building UIs for models and fitting). [#2725]
|
|
|
|
|
+ A dict-like meta member was added to Model. it is to be used to
|
|
|
|
|
store any optional information which is relevant to a project
|
|
|
|
|
and is not in the standard Model class. [#2189]
|
|
|
|
|
+ Added Ellipse2D model. [#3124]
|
|
|
|
|
- astropy.nddata
|
|
|
|
|
+ New array-related utility functions in astropy.nddata.utils for
|
|
|
|
|
adding and removing arrays from other arrays with different
|
|
|
|
|
sizes/shapes. [#3201]
|
|
|
|
|
+ New metaclass NDDataBase for enforcing the nddata interface in
|
|
|
|
|
subclasses without restricting implementation of the data
|
|
|
|
|
storage. [#2905]
|
|
|
|
|
+ New mixin classes NDSlicingMixin for slicing, NDArithmeticMixin
|
|
|
|
|
for arithmetic operations, and NDIOMixin for input/ouput in
|
|
|
|
|
NDData. [#2905]
|
|
|
|
|
+ Added a decorator support_nddata that can be used to write
|
|
|
|
|
functions that can either take separate arguments or NDData
|
|
|
|
|
objects. [#2855]
|
|
|
|
|
- astropy.stats
|
|
|
|
|
+ Added mad_std() function. [#3208]
|
|
|
|
|
+ Added gaussian_fwhm_to_sigma and gaussian_sigma_to_fwhm
|
|
|
|
|
constants. [#3208]
|
|
|
|
|
+ New function sigma_clipped_stats which can be used to quickly
|
|
|
|
|
get common statistics for an array, using sigma clipping at the
|
|
|
|
|
same time. [#3201]
|
|
|
|
|
- astropy.table
|
|
|
|
|
+ Changed the internal implementation of the Table class changed
|
|
|
|
|
so that it no longer uses numpy structured arrays as the core
|
|
|
|
|
table data container. [#2790, #3179]
|
|
|
|
|
+ Tables can now be written to an html file that includes
|
|
|
|
|
interactive browsing capabilities. To write out to this format,
|
|
|
|
|
use Table.write('filename.html', format='jsviewer'). [#2875]
|
|
|
|
|
+ A quantity property and to method were added to Table columns
|
|
|
|
|
that allow the column values to be easily converted to
|
|
|
|
|
astropy.units.Quantity objects. [#2950]
|
|
|
|
|
+ Add unique convenience method to table. [#3185]
|
|
|
|
|
- astropy.tests
|
|
|
|
|
+ Added a new Quantity-aware assert_quantity_allclose. [#3273]
|
|
|
|
|
- astropy.time
|
|
|
|
|
+ Time can now handle arbitrary array dimensions, with operations
|
|
|
|
|
following standard numpy broadcasting rules. [#3138]
|
|
|
|
|
- astropy.units
|
|
|
|
|
+ Support for VOUnit has been updated to be compliant with version
|
|
|
|
|
1.0 of the standard. [#2901]
|
|
|
|
|
+ Added an insert method to insert values into a Quantity object.
|
|
|
|
|
This is similar to the numpy.insert function. [#3049]
|
|
|
|
|
+ When viewed in IPython, Quantity objects with array values now
|
|
|
|
|
render using LaTeX and scientific notation. [#2271]
|
|
|
|
|
+ Added units.quantity_input decorator to validate quantity inputs
|
|
|
|
|
to a function for unit compatibility. [#3072]
|
|
|
|
|
+ Added units.astronomical_unit as a long form for
|
|
|
|
|
units.au. [#3303]
|
|
|
|
|
- astropy.utils
|
|
|
|
|
+ Added a new decorator astropy.utils.wraps which acts as a
|
|
|
|
|
replacement for the standard library's functools.wraps, the only
|
|
|
|
|
difference being that the decorated function also preserves the
|
|
|
|
|
wrapped function's call signature. [#2849]
|
|
|
|
|
+ astropy.utils.compat.numpy has been revised such that it can
|
|
|
|
|
include patched versions of routines from newer numpy versions.
|
|
|
|
|
The first addition is a version of broadcast_arrays that can be
|
|
|
|
|
used with Quantity and other ndarray subclasses (using the
|
|
|
|
|
subok=True flag). [#2327]
|
|
|
|
|
+ Added astropy.utils.resolve_name which returns a member of a
|
|
|
|
|
module or class given the fully qualified dotted name of that
|
|
|
|
|
object as a string. [#3389]
|
|
|
|
|
+ Added astropy.utils.minversion which can be used to check
|
|
|
|
|
minimum version requirements of Python modules (to test for
|
|
|
|
|
specific features and/ or bugs and the like). [#3389]
|
|
|
|
|
- astropy.visualization
|
|
|
|
|
+ Created astropy.visualization module and added functionality
|
|
|
|
|
relating to image normalization (i.e. stretching and scaling) as
|
|
|
|
|
well as a new script fits2bitmap that can produce a bitmap image
|
|
|
|
|
from a FITS file. [#3201]
|
|
|
|
|
+ Added dictionary
|
|
|
|
|
astropy.visualization.mpl_style.astropy_mpl_style which can be
|
|
|
|
|
used to set a uniform plotstyle specifically for tutorials that
|
|
|
|
|
is improved compared to matplotlib defaults. [#2719, #2787,
|
|
|
|
|
#3200]
|
|
|
|
|
- astropy.wcs
|
|
|
|
|
+ wcslib has been upgraded to version 4.25. This brings a single
|
|
|
|
|
new feature:
|
|
|
|
|
+ equinox and radesys will now be given default values conforming
|
|
|
|
|
with the WCS specification if EQUINOXa and RADESYa,
|
|
|
|
|
respectively, are not present in the header.
|
|
|
|
|
+ The minimum required version of wcslib is now 4.24. [#2503]
|
|
|
|
|
+ Added a new function wcs_to_celestial_frame that can be used to
|
|
|
|
|
find the astropy.coordinates celestial frame corresponding to a
|
|
|
|
|
particular WCS. [#2730]
|
|
|
|
|
+ astropy.wcs.WCS.compare now supports a tolerance keyword
|
|
|
|
|
argument to allow for approximate comparison of floating-point
|
|
|
|
|
values. [#2503]
|
|
|
|
|
+ added pixel_scale_matrix, celestial, is_celestial, and
|
|
|
|
|
has_celestial convenience attributes. Added
|
|
|
|
|
proj_plane_pixel_scales, proj_plane_pixel_area, and
|
|
|
|
|
non_celestial_pixel_scales utility functions for retrieving WCS
|
|
|
|
|
pixel scale and area information [#2832, #3304]
|
|
|
|
|
+ Added two functions pixel_to_skycoord and skycoord_to_pixel that
|
|
|
|
|
make it easy to convert between SkyCoord objects and pixel
|
|
|
|
|
coordinates. [#2885]
|
|
|
|
|
+ all_world2pix now uses a much more sophisticated and complete
|
|
|
|
|
algorithm to iteratively compute the inverse WCS
|
|
|
|
|
transform. [#2816]
|
|
|
|
|
+ Add ability to use WCS object to define projections in
|
|
|
|
|
Matplotlib, using the WCSAxes package. [#3183]
|
|
|
|
|
+ Added is_proj_plane_distorted for testing if pixels are
|
|
|
|
|
distorted. [#3329]
|
|
|
|
|
- Misc
|
|
|
|
|
+ astropy._erfa was added as a new subpackage wrapping the
|
|
|
|
|
functionality of the ERFA library in python. This is primarily
|
|
|
|
|
of use for other astropy subpackages, but the API may be made
|
|
|
|
|
more public in the future. [#2992]
|
|
|
|
|
* API Changes
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
+ Subclasses of BaseCoordinateFrame which define a custom repr
|
|
|
|
|
should be aware of the format expected in SkyCoord.__repr__(),
|
|
|
|
|
which changed in this release. [#2704, #2882]
|
|
|
|
|
+ The CartesianPoints class (deprecated in v0.4) has now been
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
+ The previous astropy.coordinates.builtin_frames module is now a
|
|
|
|
|
subpackage. Everything that was in the
|
|
|
|
|
astropy.coordinates.builtin_frames module is still accessible
|
|
|
|
|
from the new package, but the classes are now in separate
|
|
|
|
|
modules. This should have no direct impact at the user
|
|
|
|
|
level. [#3120]
|
|
|
|
|
+ Support for passing a frame as a positional argument in the
|
|
|
|
|
SkyCoord class has now been deprecated, except in the case where
|
|
|
|
|
a frame with data is passed as the sole positional
|
|
|
|
|
argument. [#3152]
|
|
|
|
|
+ Improved __repr__ of coordinate objects representing a single
|
|
|
|
|
coordinate point for the sake of easier copy/pasting. [#3350]
|
|
|
|
|
- astropy.cosmology
|
|
|
|
|
+ The functional interface to the cosmological routines as well as
|
|
|
|
|
set_current and get_current (deprecated in v0.4) have now been
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
+ Added a new argument to htmldict in the HTML reader named
|
|
|
|
|
parser, which allows the user to specify which parser
|
|
|
|
|
BeautifulSoup should use as a backend. [#2815]
|
|
|
|
|
+ Add FixedWidthTwoLine reader to guessing. This will allows to
|
|
|
|
|
read tables that a copied from screen output like print my_table
|
|
|
|
|
to be read automatically. Discussed in #3025 and #3099 [#3109]
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
+ A new optional argument cache has been added to
|
|
|
|
|
astropy.io.fits.open(). When opening a FITS file from a URL,
|
|
|
|
|
cache is a boolean value specifying whether or not to save the
|
|
|
|
|
file locally in Astropy's download cache (True by
|
|
|
|
|
default). [#3041]
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
+ Model classes should now specify inputs and outputs class
|
|
|
|
|
attributes instead of the old n_inputs and n_outputs. These
|
|
|
|
|
should be tuples providing human-readable *labels* for all
|
|
|
|
|
inputs and outputs of the model. The length of the tuple
|
|
|
|
|
indicates the numbers of inputs and outputs. See "What's New in
|
|
|
|
|
Astropy 1.0" for more details. [#2835]
|
|
|
|
|
+ It is no longer necessary to include __init__ or __call__
|
|
|
|
|
definitions in Model subclasses if all they do is wrap the
|
|
|
|
|
super-method in order to provide a nice call signature to the
|
|
|
|
|
docs. The inputs class attribute is now used to generate a nice
|
|
|
|
|
call signature, so these methods should only be overridden by
|
|
|
|
|
Model subclasses in order to provide new functionality. [#2835]
|
|
|
|
|
+ Most models included in Astropy now have sensible default values
|
|
|
|
|
for most or all of their parameters. Call help(ModelClass) on
|
|
|
|
|
any model to check what those defaults are. Most of them time
|
|
|
|
|
they should be overridden, but some of them are useful (for
|
|
|
|
|
example spatial offsets are always set at the origin by
|
|
|
|
|
default). Another rule of thumb is that, where possible, default
|
|
|
|
|
parameters are set so that the model is a no-op, or close to it,
|
|
|
|
|
by default. [#2932]
|
|
|
|
|
+ The Model.inverse method has been changed to a *property*, so
|
|
|
|
|
that now accessing model.inverse on a model returns a new model
|
|
|
|
|
that implements that model's inverse, and *calling*
|
|
|
|
|
model.inverse(...)` on some independent variable computes the
|
|
|
|
|
value of the inverse (similar to what the old Model.invert()
|
|
|
|
|
method was meant to do). [#3024]
|
|
|
|
|
+ The Model.invert() method has been removed entirely (it was
|
|
|
|
|
never implemented and there should not be any existing code that
|
|
|
|
|
relies on it). [#3024]
|
|
|
|
|
+ custom_model_1d is deprecated in favor of the new custom_model
|
|
|
|
|
(see "New Features" above). [#1763]
|
|
|
|
|
+ The Model.param_dim property (deprecated in v0.4) has now been
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
+ The Beta1D and Beta2D models have been renamed to Moffat1D and
|
|
|
|
|
Moffat2D. [#3029]
|
|
|
|
|
- astropy.nddata
|
|
|
|
|
+ flags, shape, size, dtype and ndim properties removed from
|
|
|
|
|
astropy.nddata.NDData. [#2905]
|
|
|
|
|
+ Arithmetic operations, uncertainty propagation, slicing and
|
|
|
|
|
automatic conversion to a numpy array removed from
|
|
|
|
|
astropy.nddata.NDData. The class astropy.nddata.NDDataArray is
|
|
|
|
|
functionally equivalent to the old NDData. [#2905]
|
|
|
|
|
- astropy.table
|
|
|
|
|
+ The Column.units property (deprecated in v0.3) has now been
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
+ The Row.data and Table._data attributes have been deprecated
|
|
|
|
|
related to the change in Table implementation. They are
|
|
|
|
|
replaced by Row.as_void() and Table.as_array() methods,
|
|
|
|
|
respectively. [#2790]
|
|
|
|
|
+ The Table.create_mask method has been removed. This
|
|
|
|
|
undocumented method was a development orphan and would cause
|
|
|
|
|
corruption of the table if called. [#2790]
|
|
|
|
|
+ The return type for integer item access to a Column
|
|
|
|
|
(e.g. col[12] or t['a'][12]) is now always a numpy scalar, numpy
|
|
|
|
|
ndarray, or numpy MaskedArray. Previously if the column was
|
|
|
|
|
multidimensional then a Column object would be returned. [#3095]
|
|
|
|
|
+ The representation of Table and Column objects has been changed
|
|
|
|
|
to be formatted similar to the print output. [#3239]
|
|
|
|
|
- astropy.time
|
|
|
|
|
+ The Time.val and Time.vals properties (deprecated in v0.3) and
|
|
|
|
|
the Time.lon, and Time.lat properties (deprecated in v0.4) have
|
|
|
|
|
now been removed. [#2990]
|
|
|
|
|
+ Add decimalyear format that represents time as a decimal
|
|
|
|
|
year. [#3265]
|
|
|
|
|
- astropy.units
|
|
|
|
|
+ Support for VOUnit has been updated to be compliant with version
|
|
|
|
|
1.0 of the standard. This means that some VOUnit strings that
|
|
|
|
|
were rejected before are now acceptable. [#2901] Notably:
|
|
|
|
|
- SI prefixes are supported on most units
|
|
|
|
|
- Binary prefixes are supported on "bits" and "bytes"
|
|
|
|
|
- Custom units can be defined "inline" by placing them between single
|
|
|
|
|
quotes.
|
|
|
|
|
+ Unit.get_converter has been deprecated. It is not strictly
|
|
|
|
|
necessary for end users, and it was confusing due to lack of
|
|
|
|
|
support for Quantity objects. [#3456]
|
|
|
|
|
- astropy.utils
|
|
|
|
|
+ Some members of astropy.utils.misc were moved into new
|
|
|
|
|
submodules. Specifically:
|
|
|
|
|
- deprecated, deprecated_attribute, and lazyproperty ->
|
|
|
|
|
astropy.utils.decorators
|
|
|
|
|
- find_current_module, find_mod_objs ->
|
|
|
|
|
astropy.utils.introspection
|
|
|
|
|
All of these functions can be imported directly from
|
|
|
|
|
astropy.utils which should be preferred over referencing
|
|
|
|
|
individual submodules of astropy.utils. [#2857]
|
|
|
|
|
+ The ProgressBar.iterate class method (deprecated in v0.3) has
|
|
|
|
|
now been removed. [#2990]
|
|
|
|
|
+ Updated astropy/utils/console.py ProgressBar() module to display
|
|
|
|
|
output to IPython notebook with the addition of an interactive
|
|
|
|
|
kwarg. [#2658] [#2789]
|
|
|
|
|
- astropy.wcs
|
|
|
|
|
+ The WCS.calcFootprint method (deprecated in v0.4) has now been
|
|
|
|
|
removed. [#2990]
|
|
|
|
|
+ An invalid unit in a CUNITn keyword now displays a warning and
|
|
|
|
|
returns a UnrecognizedUnit instance rather than raising an
|
|
|
|
|
exception [#3190]
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
- astropy.convolution
|
|
|
|
|
+ astropy.convolution.discretize_model now handles arbitrary
|
|
|
|
|
callables correctly [#2274].
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
+ Angle.to_string now outputs unicode arrays instead of object
|
|
|
|
|
arrays. [#2981]
|
|
|
|
|
+ SkyCoord.to_string no longer gives an error when used with an
|
|
|
|
|
array coordinate with more than one dimension. [#3340]
|
|
|
|
|
+ Fixed support for subclasses of UnitSphericalRepresentation and
|
|
|
|
|
SphericalRepresentation [#3354, #3366]
|
|
|
|
|
+ Fixed latex display of array angles in IPython notebook. [#3480]
|
|
|
|
|
- astropy.io.ascii
|
|
|
|
|
+ In the CommentedHeader the data_start parameter now defaults to
|
|
|
|
|
0, which is the first uncommented line. Discussed in
|
|
|
|
|
#2692. [#3054]
|
|
|
|
|
+ Position lines in FixedWidthTwoLine reader could consist of many
|
|
|
|
|
characters. Now, only one character in addition to the
|
|
|
|
|
delimiter is allowed. This bug was discovered as part of [#3109]
|
|
|
|
|
+ The IPAC table writer now consistently uses the fill_values
|
|
|
|
|
keyword to specify the output null values. Previously the
|
|
|
|
|
behavior was inconsistent or incorrect. [#3259]
|
|
|
|
|
+ The IPAC table reader now correctly interprets abbreviated
|
|
|
|
|
column types. [#3279]
|
|
|
|
|
+ Tables that look almost, but not quite like DAOPhot tables could
|
|
|
|
|
cause guessing to fail. [#3342]
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
+ Fixed the problem in fits.open of some filenames with colon (:)
|
|
|
|
|
in the name being recognized as URLs instead of file
|
|
|
|
|
names. [#3122]
|
|
|
|
|
+ Setting memmap=True in fits.open and related functions now
|
|
|
|
|
raises a ValueError if opening a file in memory-mapped mode is
|
|
|
|
|
impossible. [#2298]
|
|
|
|
|
+ CONTINUE cards no longer end the value of the final card in the
|
|
|
|
|
series with an ampersand, per the specification of the CONTINUE
|
|
|
|
|
card convention. [#3282]
|
|
|
|
|
+ Fixed a crash that occurred when reading an ASCII table
|
|
|
|
|
containing zero-precision floating point fields. [#3422]
|
|
|
|
|
+ When a float field for an ASCII table has zero-precision a
|
|
|
|
|
decimal point (with no digits following it) is still written to
|
|
|
|
|
the field as long as there is space for it, as recommended by
|
|
|
|
|
the FITS standard. This makes it less ambiguous that these
|
|
|
|
|
columns should be interpreted as floats. [#3422]
|
|
|
|
|
- astropy.logger
|
|
|
|
|
+ Fix a bug that occurred when displaying warnings that produced
|
|
|
|
|
an error message dictionary changed size during
|
|
|
|
|
iteration. [#3353]
|
|
|
|
|
- astropy.modeling
|
|
|
|
|
+ Fixed a bug in SLSQPLSQFitter where the maxiter argument was not
|
|
|
|
|
passed correctly to the optimizer. [#3339]
|
|
|
|
|
- astropy.table
|
|
|
|
|
+ Fix a problem where table.hstack fails to stack multiple
|
|
|
|
|
references to the same table, e.g. table.hstack([t, t]). [#2995]
|
|
|
|
|
+ Fixed a problem where table.vstack and table.hstack failed to
|
|
|
|
|
stack a single table, e.g. table.vstack([t]). [#3313]
|
|
|
|
|
+ Fix a problem when doing nested iterators on a single
|
|
|
|
|
table. [#3358]
|
|
|
|
|
+ Fix an error when an empty list, tuple, or ndarray is used for
|
|
|
|
|
item access within a table. This now returns the table with no
|
|
|
|
|
rows. [#3442]
|
|
|
|
|
- astropy.time
|
|
|
|
|
+ When creating a Time object from a datetime object the time zone
|
|
|
|
|
info is now correctly used. [#3160]
|
|
|
|
|
+ For Time objects, it is now checked that numerical input is
|
|
|
|
|
finite. [#3396]
|
|
|
|
|
- astropy.units
|
|
|
|
|
+ Added a latex_inline unit format that returns the units in LaTeX
|
|
|
|
|
math notation with negative exponents instead of fractions
|
|
|
|
|
[#2622].
|
|
|
|
|
+ When using a unit that is deprecated in a given unit format,
|
|
|
|
|
non-deprecated alternatives will be suggested. [#2806] For
|
|
|
|
|
example::
|
|
|
|
|
>>> import astropy.units as u
|
|
|
|
|
>>> u.Unit('Angstrom', format='fits')
|
|
|
|
|
WARNING: UnitsWarning: The unit 'Angstrom' has been deprecated
|
|
|
|
|
in the FITS standard. Suggested: nm (with data multiplied by
|
|
|
|
|
0.1). [astropy.units.format.utils]
|
|
|
|
|
- astropy.utils
|
|
|
|
|
+ treat_deprecations_as_exceptions has been fixed to recognize
|
|
|
|
|
Astropy deprecation warnings. [#3015]
|
|
|
|
|
- astropy.wcs
|
|
|
|
|
+ astropy.wcs.WCS.sub now accepts unicode strings as input on
|
|
|
|
|
Python 2.x [#3356]
|
|
|
|
|
- Misc
|
|
|
|
|
+ Some modules and tests that would crash upon import when using a
|
|
|
|
|
non-final release of Numpy (e.g. 1.9.0rc1). [#3471]
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
- The bundled copy of astropy-helpers has been updated to
|
|
|
|
|
v1.0. [#3515]
|
|
|
|
|
- The bundled copy of astropy-helpers has been updated to
|
|
|
|
|
v1.0. [#3513]
|
|
|
|
|
- Updated astropy.extern.configobj to Version 5. Version 5 uses
|
|
|
|
|
six and the same code covers both Python 2 and Python 3. [#3149]
|
|
|
|
|
- astropy.coordinates
|
|
|
|
|
+ The repr of SkyCoord and coordinate frame classes now separate
|
|
|
|
|
frame attributes and coordinate information. [#2704, #2882]
|
|
|
|
|
- astropy.io.fits
|
|
|
|
|
+ Overwriting an existing file using the clobber=True option no
|
|
|
|
|
longer displays a warning message. [#1963]
|
|
|
|
|
+ fits.open no longer catches OSError exceptions on missing or
|
|
|
|
|
unreadable files-- instead it raises the standard Python
|
|
|
|
|
exceptions in such cases. [#2756, #2785]
|
|
|
|
|
- astropy.table
|
|
|
|
|
+ Sped up setting of Column slices by an order of
|
|
|
|
|
magnitude. [#2994, #3020]
|
|
|
|
|
- Updated the bundled six module to version 1.7.3 and made 1.7.3
|
|
|
|
|
the minimum acceptable version of six. [#2814]
|
|
|
|
|
- The version of ERFA included with Astropy is now v1.1.1 [#2971]
|
|
|
|
|
- The code base is now fully Python 2 and 3 compatible and no
|
|
|
|
|
longer requires 2to3. [#2033]
|
|
|
|
|
- `funcsigs <https://pypi.python.org/pypi/funcsigs>`_ is included
|
|
|
|
|
in utils.compat, but defaults to the inspect module components
|
|
|
|
|
where available (3.3+) [#3151].
|
|
|
|
|
- The list of modules displayed in the pytest header can now be
|
|
|
|
|
customized. [#3157]
|
|
|
|
|
- `jinja2 <http://jinja.pocoo.org/docs/dev/>`_>=2.7 is now
|
|
|
|
|
required to build the source code from the git repository, in
|
|
|
|
|
order to allow the ERFA wrappers to be generated. [#3166]
|
|
|
|
|
- update to version 0.4.4:
|
|
|
|
|
* astropy.vo.samp
|
|
|
|
|
+ astropy.vo.samp is now usable on Python builds that do not
|
|
|
|
|
support the SSLv3 protocol (which depends both on the version of
|
|
|
|
|
Python and the version of OpenSSL or LibreSSL that it is built
|
|
|
|
|
against.) [#3308]
|
|
|
|
|
+ The default SSL protocol used is now determined from the default
|
|
|
|
|
used in the Python ssl standard library. This default may be
|
|
|
|
|
different depending on the exact version of Python you are
|
|
|
|
|
using. [#3308]
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
+ WCS allows slices of the form slice(None, x, y), which
|
|
|
|
|
previously resulted in an unsliced copy being returned (note:
|
|
|
|
|
this was previously incorrectly reported as fixed in v0.4.3)
|
|
|
|
|
[#2909]
|
|
|
|
|
- changes from version 0.4.3:
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
+ The Distance class has been fixed to no longer rely on the
|
|
|
|
|
deprecated cosmology functions. [#2991]
|
|
|
|
|
+ Ensure float32 values can be used in coordinate
|
|
|
|
|
representations. [#2983]
|
|
|
|
|
+ Fix frame attribute inheritance in SkyCoord.transform_to()
|
|
|
|
|
method so that the default attribute value (e.g. equinox) for
|
|
|
|
|
the destination frame gets used if no corresponding value was
|
|
|
|
|
explicitly specified. [#3106]
|
|
|
|
|
+ Angle accepts hours:mins or deg:mins initializers (without
|
|
|
|
|
seconds). In these cases float minutes are also accepted.
|
|
|
|
|
+ astropy.coordinates.SkyCoord objects are now copyable. [#2888 ]
|
|
|
|
|
+ astropy.coordinates.SkyCoord object attributes are now
|
|
|
|
|
immutable. It is still technically possible to change the
|
|
|
|
|
internal data for an array-valued coordinate object but this
|
|
|
|
|
leads to inconsistencies [#2889] and should not be done. [#2888]
|
|
|
|
|
* astropy.cosmology
|
|
|
|
|
+ The ztol keyword argument to z_at_value now works correctly
|
|
|
|
|
[#2993].
|
|
|
|
|
* astropy.io.ascii
|
|
|
|
|
+ Fix a bug in Python 3 when guessing file format using a file
|
|
|
|
|
object as input. Also improve performance in same situation for
|
|
|
|
|
Python 2. [#3132]
|
|
|
|
|
+ Fix a problem where URL was being downloaded for each
|
|
|
|
|
guess. [#2001]
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
+ The in operator now works correctly for checking if an extension
|
|
|
|
|
is in an HDUList (as given via EXTNAME, (EXTNAME, EXTVER)
|
|
|
|
|
tuples, etc.) [#3060]
|
|
|
|
|
+ Added workaround for bug in MacOS X <= 10.8 that caused
|
|
|
|
|
np.fromfile to fail. [#3078]
|
|
|
|
|
+ Added support for the RICE_ONE compression type synonym. [#3115]
|
|
|
|
|
* astropy.modeling
|
|
|
|
|
+ Fixed a test failure on Debian/PowerPC and Debian/s390x. [#2708]
|
|
|
|
|
+ Fixed crash in evaluating models that have more outputs than
|
|
|
|
|
inputs--this case may not be handled as desired for all
|
|
|
|
|
conceivable models of this format (some may have to implement
|
|
|
|
|
custom prepare_inputs and prepare_outputs methods). But as long
|
|
|
|
|
as all outputs can be assumed to have a shape determined from
|
|
|
|
|
the broadcast of all inputs with all parameters then this can be
|
|
|
|
|
used safely. [#3250]
|
|
|
|
|
* astropy.table
|
|
|
|
|
+ Fix a bug that caused join to fail for multi-dimensional
|
|
|
|
|
columns. [#2984]
|
|
|
|
|
+ Fix a bug where MaskedColumn attributes which had been changed
|
|
|
|
|
since the object was created were not being carried through when
|
|
|
|
|
slicing. [#3023]
|
|
|
|
|
+ Fix a bug that prevented initializing a table from a structured
|
|
|
|
|
array with multi-dimensional columns with copy=True. [#3034]
|
|
|
|
|
+ Fixed unnecessarily large unicode columns when instantiating a
|
|
|
|
|
table from row data on Python 3. [#3052]
|
|
|
|
|
+ Improved the warning message when unable to aggregate
|
|
|
|
|
non-numeric columns. [#2700]
|
|
|
|
|
* astropy.units
|
|
|
|
|
+ Operations on quantities with incompatible types now raises a
|
|
|
|
|
much more informative TypeError. [#2934]
|
|
|
|
|
+ Quantity.tolist now overrides the ndarray method to give a
|
|
|
|
|
NotImplementedError (by renaming the previous list
|
|
|
|
|
method). [#3050]
|
|
|
|
|
+ Quantity.round now always returns a Quantity (previously it
|
|
|
|
|
returned an ndarray for decimals>0). [#3062]
|
|
|
|
|
+ Ensured np.squeeze always returns a Quantity (it only worked if
|
|
|
|
|
no dimensions were removed). [#3045]
|
|
|
|
|
+ Input to Quantity with a unit attribute no longer can get
|
|
|
|
|
mangled with copy=False. [#3051]
|
|
|
|
|
+ Remove trailing space in __format__ calls for dimensionless
|
|
|
|
|
quantities. [#3097]
|
|
|
|
|
+ Comparisons between units and non-unit-like objects now works
|
|
|
|
|
correctly. [#3108]
|
|
|
|
|
+ Units with fractional powers are now correctly multiplied
|
|
|
|
|
together by using rational arithmetic. [#3121]
|
|
|
|
|
+ Removed a few entries from spectral density equivalencies which
|
|
|
|
|
did not make sense. [#3153]
|
|
|
|
|
* astropy.utils
|
|
|
|
|
+ Fixed an issue with the deprecated decorator on classes that
|
|
|
|
|
invoke super() in their __init__ method. [#3004]
|
|
|
|
|
+ Fixed a bug which caused the metadata_conflicts parameter to be
|
|
|
|
|
ignored in the astropy.utils.metadata.merge function. [#3294]
|
|
|
|
|
* astropy.vo
|
|
|
|
|
+ Fixed an issue with reconnecting to a SAMP Hub. [#2674 ]
|
|
|
|
|
* astropy.wcs
|
|
|
|
|
+ Invalid or out of range values passed to wcs_world2pix will now
|
|
|
|
|
be correctly identified and returned as nan values. [#2965]
|
|
|
|
|
+ Fixed an issue which meant that Python thought WCS objects were
|
|
|
|
|
iterable. [#3066]
|
|
|
|
|
* Misc
|
|
|
|
|
+ Astropy will now work if your Python interpreter does not have
|
|
|
|
|
the bz2 module installed. [#3104]
|
|
|
|
|
+ Fixed ResourceWarning for astropy/extern/bundled/six.py that
|
|
|
|
|
could occur sometimes after using Astropy in Python 3.4. [#3156]
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
+ Improved the agreement of the FK5 <-> Galactic conversion with
|
|
|
|
|
other codes, and with the FK5 <-> FK4 <-> Galactic
|
|
|
|
|
route. [#3107]
|
|
|
|
|
- specfile:
|
|
|
|
|
* update copyright year
|
|
|
|
|
* added libhdf5 requirement
|
|
|
|
|
- update to version 0.4.2:
|
|
|
|
|
* astropy.coordinates
|
|
|
|
|
- Angle accepts hours:mins or deg:mins initializers (without
|
|
|
|
|
seconds). In these cases float minutes are also accepted.
|
|
|
|
|
- The repr for coordinate frames now displays the frame
|
|
|
|
|
attributes (ex: ra, dec) in a consistent order. It should be
|
|
|
|
|
noted that as part of this fix, the
|
|
|
|
|
BaseCoordinateFrame.get_frame_attr_names() method now returns
|
|
|
|
|
an OrderedDict instead of just a dict. [#2845]
|
|
|
|
|
* astropy.io.fits
|
|
|
|
|
- Fixed a crash when reading scaled float data out of a FITS file
|
|
|
|
|
that was loaded from a string (using HDUList.fromfile) rather
|
|
|
|
|
than from a file. [#2710]
|
|
|
|
|
- Fixed a crash when reading data from an HDU whose header
|
|
|
|
|
contained in invalid value for the BLANK keyword (e.g., a string
|
|
|
|
|
value instead of an integer as required by the FITS
|
|
|
|
|
Standard). Invalid BLANK keywords are now warned about, but are
|
|
|
|
|
otherwise ignored. [#2711]
|
|
|
|
|
- Fixed a crash when reading the header of a tile-compressed HDU
|
|
|
|
|
if that header contained invalid duplicate keywords resulting in
|
|
|
|
|
a KeyError [#2750]
|
|
|
|
|
- Fixed crash when reading gzip-compressed FITS tables through the
|
|
|
|
|
Astropy Table interface. [#2783]
|
|
|
|
|
- Fixed corruption when writing new FITS files through to gzipped
|
|
|
|
|
files. [#2794]
|
|
|
|
|
- Fixed crash when writing HDUs made with non-contiguous data
|
|
|
|
|
arrays to file-like objects. [#2794]
|
|
|
|
|
- It is now possible to create astropy.io.fits.BinTableHDU objects
|
|
|
|
|
with a table with zero rows. [#2916]
|
|
|
|
|
* astropy.io.misc
|
|
|
|
|
- Fixed a bug that prevented h5py Dataset objects from being
|
|
|
|
|
automatically recognized by Table.read. [#2831]
|
|
|
|
|
* astropy.modeling
|
|
|
|
|
- Make LevMarLSQFitter work with weights keyword. [#2900]
|
|
|
|
|
* astropy.table
|
|
|
|
|
- Fixed reference cycle in tables that could prevent Table objects
|
|
|
|
|
from being freed from memory. [#2879]
|
|
|
|
|
- Fixed an issue where Table.pprint() did not print the header to
|
|
|
|
|
stdout when stdout is redirected (say, to a file). [#2878]
|
|
|
|
|
- Fixed printing of masked values when a format is
|
|
|
|
|
specified. [#1026]
|
|
|
|
|
- Ensured that numpy ufuncs that return booleans return plain
|
|
|
|
|
ndarray instances, just like the comparison operators. [#2963]
|
|
|
|
|
* astropy.time
|
|
|
|
|
- Ensure bigendian input to Time works on a little-endian machine
|
|
|
|
|
(and vice versa). [#2942]
|
|
|
|
|
* astropy.units
|
|
|
|
|
- Ensure unit is kept when adding 0 to quantities. [#2968]
|
|
|
|
|
* astropy.utils
|
|
|
|
|
- Fixed color printing on Windows with IPython 2.0. [#2878]
|
|
|
|
|
* astropy.vo
|
|
|
|
|
- Improved error message on Cone Search time out. [#2687]
|
|
|
|
|
* Fixed a couple issues with files being inappropriately included
|
|
|
|
|
and/or excluded from the source archive distributions of
|
|
|
|
|
Astropy. [#2843, #2854]
|
|
|
|
|
* As part of fixing the fact that masked elements of table columns
|
|
|
|
|
could not be printed when a format was specified, the column
|
|
|
|
|
format string options were expanded to allow simple specifiers
|
|
|
|
|
such as '5.2f'. [#2898]
|
|
|
|
|
* Ensure numpy 1.9 is supported. [#2917]
|
|
|
|
|
* Ensure numpy master is supported, by making np.cbrt work with
|
|
|
|
|
quantities. [#2937]

- Mark wcs headers as false positives for devel-file-in-non-devel-package
|
|
|
|
|
These are used by the python files so they must be available.
|
|
|
|
|
- Update to 0.4.1 (2014-08-08)
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
- Fixed a bug where an unedited configuration file from astropy
|
|
|
|
|
0.3.2 would not be correctly identified as unedited. [#2772] This
|
|
|
|
|
resulted in the warning::
|
|
|
|
|
WARNING: ConfigurationChangedWarning: The configuration options
|
|
|
|
|
in astropy 0.4 may have changed, your configuration file was not
|
|
|
|
|
updated in order to preserve local changes. A new configuration
|
|
|
|
|
template has been saved to
|
|
|
|
|
'~/.astropy/config/astropy.0.4.cfg'. [astropy.config.configuration]
|
|
|
|
|
- Fixed the error message that is displayed when an old
|
|
|
|
|
configuration item has moved. Before, the destination
|
|
|
|
|
section was wrong. [#2772]
|
|
|
|
|
- Added configuration settings for ``io.fits``, ``io.votable`` and
|
|
|
|
|
``table.jsviewer`` that were missing from the configuration file
|
|
|
|
|
template. [#2772]
|
|
|
|
|
- The configuration template is no longer rewritten on every import
|
|
|
|
|
of astropy, causing race conditions. [#2805]
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|
- Fixed the multiplication of ``Kernel`` with numpy floats. [#2174]
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
- ``Distance`` can now take a list of quantities. [#2261]
|
|
|
|
|
- For in-place operations for ``Angle`` instances in which the result unit
|
|
|
|
|
is not an angle, an exception is raised before the instance is corrupted.
|
|
|
|
|
[#2718]
|
|
|
|
|
- ``CartesianPoints`` are now deprecated in favor of
|
|
|
|
|
``CartesianRepresentation``. [#2727]
|
|
|
|
|
- ``astropy.io.misc``
|
|
|
|
|
- An existing table within an HDF5 file can be overwritten without affecting
|
|
|
|
|
other datasets in the same HDF5 file by simultaneously using
|
|
|
|
|
``overwrite=True`` and ``append=True`` arguments to the ``Table.write``
|
|
|
|
|
method. [#2624]
|
|
|
|
|
- ``astropy.logger``
|
|
|
|
|
- Fixed a crash that could occur in rare cases when (such as in bundled
|
|
|
|
|
apps) where submodules of the ``email`` package are not importable. [#2671]
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
- ``astropy.nddata.NDData()`` no longer raises a ``ValueError`` when passed
|
|
|
|
|
a numpy masked array which has no masked entries. [#2784]
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
- When saving a table to a FITS file containing a unit that is not
|
|
|
|
|
supported by the FITS standard, a warning rather than an exception
|
|
|
|
|
is raised. [#2797]
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
- By default, ``Quantity`` and its subclasses will now convert to float also
|
|
|
|
|
numerical types such as ``decimal.Decimal``, which are stored as objects
|
|
|
|
|
by numpy. [#1419]
|
|
|
|
|
- The units ``count``, ``pixel``, ``voxel`` and ``dbyte`` now output
|
|
|
|
|
to FITS, OGIP and VOUnit formats correctly. [#2798]
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
- Restored missing information from deprecation warning messages
|
|
|
|
|
from the ``deprecated`` decorator. [#2811]
|
|
|
|
|
- Fixed support for ``staticmethod`` deprecation in the ``deprecated``
|
|
|
|
|
decorator. [#2811]
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
- Fixed a memory leak when ``astropy.wcs.WCS`` objects are copied
|
|
|
|
|
[#2754]
|
|
|
|
|
- Fixed a crash when passing ``ra_dec_order=True`` to any of the
|
|
|
|
|
``*2world`` methods. [#2791]
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
- Bundled copy of astropy-helpers upgraded to v0.4.1. [#2825]
|
|
|
|
|
- General improvements to documentation and docstrings [#2722, #2728, #2742]
|
|
|
|
|
- Made it easier for third-party packagers to have Astropy use their own
|
|
|
|
|
version of the ``six`` module (so long as it meets the minimum version
|
|
|
|
|
requirement) and remove the copy bundled with Astropy. See the
|
|
|
|
|
astropy/extern/README file in the source tree. [#2623]
|
|
|
|
|
- Update to 0.4 (2014-07-16)
|
|
|
|
|
* New Features
|
|
|
|
|
- ``astropy.constants``
|
|
|
|
|
- Added ``b_wien`` to represent Wien wavelength displacement law constant.
|
|
|
|
|
[#2194]
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|
- Changed the input parameter in ``Gaussian1DKernel`` and
|
|
|
|
|
``Gaussian2DKernel`` from ``width`` to ``stddev`` [#2085].
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
- The coordinates package has undergone major changes to implement
|
|
|
|
|
`APE5 <https://github.com/astropy/astropy-APEs/blob/master/APE5.rst>`_ .
|
|
|
|
|
These include backwards-incompatible changes, as the underlying framework
|
|
|
|
|
has changed substantially. See the APE5 text and the package documentation
|
|
|
|
|
for more details. [#2422]
|
|
|
|
|
- A ``position_angle`` method has been added to the new ``SkyCoord``. [#2487]
|
|
|
|
|
- Updated ``Angle.dms`` and ``Angle.hms`` to return ``namedtuple`` -s instead
|
|
|
|
|
of regular tuples, and added ``Angle.signed_dms`` attribute that gives the
|
|
|
|
|
absolute value of the ``d``, ``m``, and ``s`` along with the sign. [#1988]
|
|
|
|
|
- By default, ``Distance`` objects are now required to be positive. To
|
|
|
|
|
allow negative values, set ``allow_negative=True`` in the ``Distance``
|
|
|
|
|
constructor when creating a ``Distance`` instance.
|
|
|
|
|
- ``Longitude`` (resp. ``Latitude``) objects cannot be used any more to
|
|
|
|
|
initialize or set ``Latitude`` (resp. ``Longitude``) objects. An explicit
|
|
|
|
|
conversion to ``Angle`` is now required. [#2461]
|
|
|
|
|
- The deprecated functions for pre-0.3 coordinate object names like
|
|
|
|
|
``ICRSCoordinates`` have been removed. [#2422]
|
|
|
|
|
- The ``rotation_matrix`` and ``angle_axis`` functions in
|
|
|
|
|
``astropy.coordinates.angles`` were made more numerically consistent and
|
|
|
|
|
are now tested explicitly [#2619]
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
- Added ``z_at_value`` function to find the redshift at which a cosmology
|
|
|
|
|
function matches a desired value. [#1909]
|
|
|
|
|
- Added ``FLRW.differential_comoving_volume`` method to give the differential
|
|
|
|
|
comoving volume at redshift z. [#2103]
|
|
|
|
|
- The functional interface is now deprecated in favor of the more-explicit
|
|
|
|
|
use of methods on cosmology objects. [#2343]
|
|
|
|
|
- Updated documentation to reflect the removal of the functional
|
|
|
|
|
interface. [#2507]
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
- The ``astropy.io.ascii`` output formats ``latex`` and ``aastex`` accept a
|
|
|
|
|
dictionary called ``latex_dict`` to specify options for LaTeX output. It is
|
|
|
|
|
now possible to specify the table alignment within the text via the
|
|
|
|
|
``tablealign`` keyword. [#1838]
|
|
|
|
|
- If ``header_start`` is specified in a call to ``ascii.get_reader`` or any
|
|
|
|
|
method that calls ``get_reader`` (e.g. ``ascii.read``) but ``data_start``
|
|
|
|
|
is not specified at the same time, then ``data_start`` is calculated so
|
|
|
|
|
that the data starts after the header. Before this, the default was
|
|
|
|
|
that the header line was read again as the first data line
|
|
|
|
|
[#855 and #1844].
|
|
|
|
|
- A new ``csv`` format was added as a convenience for handling CSV (comma-
|
|
|
|
|
separated values) data. [#1935]
|
|
|
|
|
This format also recognises rows with an inconsistent number of elements.
|
|
|
|
|
[#1562]
|
|
|
|
|
- An option was added to guess the start of data for CDS format files when
|
|
|
|
|
they do not strictly conform to the format standard. [#2241]
|
|
|
|
|
- Added an HTML reader and writer to the ``astropy.io.ascii`` package.
|
|
|
|
|
Parsing requires the installation of BeautifulSoup and is therefore
|
|
|
|
|
an optional feature. [#2160]
|
|
|
|
|
- Added support for inputting column descriptions and column units
|
|
|
|
|
with the ``io.ascii.SExtractor`` reader. [#2372]
|
|
|
|
|
- Allow the use of non-local ReadMe files in the CDS reader. [#2329]
|
|
|
|
|
- Provide a mechanism to select how masked values are printed. [#2424]
|
|
|
|
|
- Added support for reading multi-aperture daophot file. [#2656]
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
- Included a new command-line script called ``fitsheader`` to display the
|
|
|
|
|
header(s) of a FITS file from the command line. [#2092]
|
|
|
|
|
- Added new verification options ``fix+ignore``, ``fix+warn``,
|
|
|
|
|
``fix+exception``, ``silentfix+ignore``, ``silentfix+warn``, and
|
|
|
|
|
``silentfix+exception`` which give more control over how to report fixable
|
|
|
|
|
errors as opposed to unfixable errors.
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
- Prototype implementation of fitters that treat optimization algorithms
|
|
|
|
|
separately from fit statistics, allowing new fitters to be created by
|
|
|
|
|
mixing and matching optimizers and statistic functions. [#1914]
|
|
|
|
|
- Slight overhaul to how inputs to and outputs from models are handled with
|
|
|
|
|
respect to array-valued parameters and variables, as well as sets of
|
|
|
|
|
multiple models. See the associated PR and the modeling section of the
|
|
|
|
|
v0.4 documentation for more details. [#2634]
|
|
|
|
|
- Added a new ``SimplexLSQFitter`` which uses a downhill simplex optimizer
|
|
|
|
|
with a least squares statistic. [#1914]
|
|
|
|
|
- Changed ``Gaussian2D`` model such that ``theta`` now increases
|
|
|
|
|
counterclockwise. [#2199]
|
|
|
|
|
- Replaced the ``MatrixRotation2D`` model with a new model called simply
|
|
|
|
|
``Rotation2D`` which requires only an angle to specify the rotation.
|
|
|
|
|
The new ``Rotation2D`` rotates in a counter-clockwise sense whereas
|
|
|
|
|
the old ``MatrixRotation2D`` increased the angle clockwise.
|
|
|
|
|
[#2266, #2269]
|
|
|
|
|
- Added a new ``AffineTransformation2D`` model which serves as a
|
|
|
|
|
replacement for the capability of ``MatrixRotation2D`` to accept an
|
|
|
|
|
arbitrary matrix, while also adding a translation capability. [#2269]
|
|
|
|
|
- Added ``GaussianAbsorption1D`` model. [#2215]
|
|
|
|
|
- New ``Redshift`` model [#2176].
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
- Allow initialization ``NDData`` or ``StdDevUncertainty`` with a
|
|
|
|
|
``Quantity``. [#2380]
|
|
|
|
|
- ``astropy.stats``
|
|
|
|
|
- Added flat prior to binom_conf_interval and binned_binom_proportion
|
|
|
|
|
- Change default in ``sigma_clip`` from ``np.median`` to ``np.ma.median``.
|
|
|
|
|
[#2582]
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
- Note, the following new features are included in astropy-helpers as well:
|
|
|
|
|
- The ``automodapi`` and ``automodsumm`` extensions now include sphinx
|
|
|
|
|
configuration options to write out what ``automodapi`` and ``automodsumm``
|
|
|
|
|
generate, mainly for debugging purposes. [#1975, #2022]
|
|
|
|
|
- Reference documentation now shows functions/class docstrings at the
|
|
|
|
|
inteded user-facing API location rather than the actual file where
|
|
|
|
|
the implementation is found. [#1826]
|
|
|
|
|
- The ``automodsumm`` extension configuration was changed to generate
|
|
|
|
|
documentation of class ``__call__`` member functions. [#1817, #2135]
|
|
|
|
|
- ``automodapi`` and ``automodsumm`` now have an ``:allowed-package-names:``
|
|
|
|
|
option that make it possible to document functions and classes that
|
|
|
|
|
are in a different namespace. [#2370]
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
- Improved grouped table aggregation by using the numpy ``reduceat()`` method
|
|
|
|
|
when possible. This can speed up the operation by a factor of at least 10
|
|
|
|
|
to 100 for large unmasked tables and columns with relatively small
|
|
|
|
|
group sizes. [#2625]
|
|
|
|
|
- Allow row-oriented data input using a new ``rows`` keyword argument.
|
|
|
|
|
[#850]
|
|
|
|
|
- Allow subclassing of ``Table`` and the component classes ``Row``, ``Column``,
|
|
|
|
|
``MaskedColumn``, ``TableColumns``, and ``TableFormatter``. [#2287]
|
|
|
|
|
- Fix to allow numpy integer types as valid indices into tables in
|
|
|
|
|
Python 3.x [#2477]
|
|
|
|
|
- Remove transition code related to the order change in ``Column`` and
|
|
|
|
|
``MaskedColumn`` arguments ``name`` and ``data`` from Astropy 0.2
|
|
|
|
|
to 0.3. [#2511]
|
|
|
|
|
- Change HTML table representation in IPython notebook to show all
|
|
|
|
|
table columns instead of restricting to 80 column width. [#2651]
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
- Mean and apparent sidereal time can now be calculated using the
|
|
|
|
|
``sidereal_time`` method [#1418].
|
|
|
|
|
- The time scale now defaults to UTC if no scale is provided. [#2091]
|
|
|
|
|
- ``TimeDelta`` objects can have all scales but UTC, as well as, for
|
|
|
|
|
consistency with time-like quantities, undefined scale (where the
|
|
|
|
|
scale is taken from the object one adds to or subtracts from).
|
|
|
|
|
This allows, e.g., to work consistently in TDB. [#1932]
|
|
|
|
|
- ``Time`` now supports ISO format strings that end in "Z". [#2211, #2203]
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
- Support for the unit format `Office of Guest Investigator Programs (OGIP)
|
|
|
|
|
FITS files
|
|
|
|
|
<http://heasarc.gsfc.nasa.gov/docs/heasarc/ofwg/docs/general/ogip_93_001/>`__
|
|
|
|
|
has been added. [#377]
|
|
|
|
|
- The ``spectral`` equivalency can now handle angular wave number. [#1306 and
|
|
|
|
|
#1899]
|
|
|
|
|
- Added ``one`` as a shorthand for ``dimensionless_unscaled``. [#1980]
|
|
|
|
|
- Added ``dex`` and ``dB`` units. [#1628]
|
|
|
|
|
- Added ``temperature()`` equivalencies to support conversion between
|
|
|
|
|
Kelvin, Celsius, and Fahrenheit. [#2209]
|
|
|
|
|
- Added ``temperature_energy()`` equivalencies to support conversion
|
|
|
|
|
between electron-volt and Kelvin. [#2637]
|
|
|
|
|
- The runtime of ``astropy.units.Unit.compose`` is greatly improved
|
|
|
|
|
(by a factor of 2 in most cases) [#2544]
|
|
|
|
|
- Added ``electron`` unit. [#2599]
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
- ``timer.RunTimePredictor`` now uses ``astropy.modeling`` in its
|
|
|
|
|
``do_fit()`` method. [#1896]
|
|
|
|
|
- ``astropy.vo``
|
|
|
|
|
- A new sub-package, ``astropy.vo.samp``, is now available (this was
|
|
|
|
|
previously the SAMPy package, which has been refactored for use in
|
|
|
|
|
Astropy). [#1907]
|
|
|
|
|
- Enhanced functionalities for ``VOSCatalog`` and ``VOSDatabase``. [#1206]
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
- astropy now requires wcslib version 4.23 or later. The version of
|
|
|
|
|
wcslib included with astropy has been updated to version 4.23.
|
|
|
|
|
- Bounds checking is now performed on native spherical
|
|
|
|
|
coordinates. Any out-of-bounds values will be returned as
|
|
|
|
|
``NaN``, and marked in the ``stat`` array, if using the
|
|
|
|
|
low-level ``wcslib`` interface such as
|
|
|
|
|
``astropy.wcs.Wcsprm.p2s``. [#2107]
|
|
|
|
|
- A new method, ``astropy.wcs.WCS.compare()``, compares two wcsprm
|
|
|
|
|
structs for equality with varying degrees of strictness. [#2361]
|
|
|
|
|
- New ``astropy.wcs.utils`` module, with a handful of tools for manipulating
|
|
|
|
|
WCS objects, including dropping, swapping, and adding axes.
|
|
|
|
|
- Misc
|
|
|
|
|
- Includes the new astropy-helpers package which separates some of Astropy's
|
|
|
|
|
build, installation, and documentation infrastructure out into an
|
|
|
|
|
independent package, making it easier for Affiliated Packages to depend on
|
|
|
|
|
these features. astropy-helpers replaces/deprecates some of the submodules
|
|
|
|
|
in the ``astropy`` package (see API Changes below). See also
|
|
|
|
|
`APE 4 <https://github.com/astropy/astropy-APEs/blob/master/APE4.rst>`_
|
|
|
|
|
for more details on the motivation behind and implementation of
|
|
|
|
|
astropy-helpers. [#1563]
|
|
|
|
|
* API Changes
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
- The configuration system received a major overhaul, as part of APE3. It is
|
|
|
|
|
no longer possible to save configuration items from Python, but instead
|
|
|
|
|
users must edit the configuration file directly. The locations of
|
|
|
|
|
configuration items have moved, and some have been changed to science state
|
|
|
|
|
values. The old locations should continue to work until astropy 0.5, but
|
|
|
|
|
deprecation warnings will be displayed. See the `Configuration transition
|
|
|
|
|
<http://astropy.readthedocs.org/en/v0.4/config/config_0_4_transition.html>`_
|
|
|
|
|
docs for a detailed description of the changes and how to update existing
|
|
|
|
|
code. [#2094]
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
- The ``astropy.io.fits.new_table`` function is now fully deprecated (though
|
|
|
|
|
will not be removed for a long time, considering how widely it is used).
|
|
|
|
|
Instead please use the more explicit ``BinTableHDU.from_columns`` to create
|
|
|
|
|
a new binary table HDU, and the similar ``TableHDU.from_columns`` to create
|
|
|
|
|
a new ASCII table. These otherwise accept the same arguments as
|
|
|
|
|
``new_table`` which is now just a wrapper for these.
|
|
|
|
|
- The ``.fromstring`` classmethod of each HDU type has been simplified such
|
|
|
|
|
that, true to its namesake, it only initializes an HDU from a string
|
|
|
|
|
containing its header *and* data.
|
|
|
|
|
- Fixed an issue where header wildcard matching (for example
|
|
|
|
|
``header['DATE*']``) can be used to match *any* characters that might
|
|
|
|
|
appear in a keyword. Previously this only matched keywords containing
|
|
|
|
|
characters in the set ``[0-9A-Za-z_]``. Now this can also match a hyphen
|
|
|
|
|
``-`` and any other characters, as some conventions like ``HIERARCH`` and
|
|
|
|
|
record-valued keyword cards allow a wider range of valid characters than
|
|
|
|
|
standard FITS keywords.
|
|
|
|
|
- This will be the *last* release to support the following APIs that have
|
|
|
|
|
been marked deprecated since Astropy v0.1/PyFITS v3.1:
|
|
|
|
|
- The ``CardList`` class, which was part of the old header implementation.
|
|
|
|
|
- The ``Card.key`` attribute. Use ``Card.keyword`` instead.
|
|
|
|
|
- The ``Card.cardimage`` and ``Card.ascardimage`` attributes. Use simply
|
|
|
|
|
``Card.image`` or ``str(card)`` instead.
|
|
|
|
|
- The ``create_card`` factory function. Simply use the normal ``Card``
|
|
|
|
|
constructor instead.
|
|
|
|
|
- The ``create_card_from_string`` factory function. Use ``Card.fromstring``
|
|
|
|
|
instead.
|
|
|
|
|
- The ``upper_key`` function. Use ``Card.normalize_keyword`` method
|
|
|
|
|
instead (this is not unlikely to be used outside of PyFITS itself, but it
|
|
|
|
|
was technically public API).
|
|
|
|
|
- The usage of ``Header.update`` with ``Header.update(keyword, value,
|
|
|
|
|
comment)`` arguments. ``Header.update`` should only be used analogously
|
|
|
|
|
to ``dict.update``. Use ``Header.set`` instead.
|
|
|
|
|
- The ``Header.ascard`` attribute. Use ``Header.cards`` instead for a list
|
|
|
|
|
of all the ``Card`` objects in the header.
|
|
|
|
|
- The ``Header.rename_key`` method. Use ``Header.rename_keyword`` instead.
|
|
|
|
|
- The ``Header.get_history`` method. Use ``header['HISTORY']`` instead
|
|
|
|
|
(normal keyword lookup).
|
|
|
|
|
- The ``Header.get_comment`` method. Use ``header['COMMENT']`` instead.
|
|
|
|
|
- The ``Header.toTxtFile`` method. Use ``header.totextfile`` instead.
|
|
|
|
|
- The ``Header.fromTxtFile`` method. Use ``Header.fromtextfile`` instead.
|
|
|
|
|
- The ``tdump`` and ``tcreate`` functions. Use ``tabledump`` and
|
|
|
|
|
``tableload`` respectively.
|
|
|
|
|
- The ``BinTableHDU.tdump`` and ``tcreate`` methods. Use
|
|
|
|
|
``BinTableHDU.dump`` and ``BinTableHDU.load`` respectively.
|
|
|
|
|
- The ``txtfile`` argument to the ``Header`` constructor. Use
|
|
|
|
|
``Header.fromfile`` instead.
|
|
|
|
|
- The ``startColumn`` and ``endColumn`` arguments to the ``FITS_record``
|
|
|
|
|
constructor. These are unlikely to be used by any user code.
|
|
|
|
|
These deprecated interfaces will be removed from the development version of
|
|
|
|
|
Astropy following the v0.4 release (they will still be available in any
|
|
|
|
|
v0.4.x bugfix releases, however).
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
- The method computing the derivative of the model with respect
|
|
|
|
|
to parameters was renamed from ``deriv`` to ``fit_deriv``. [#1739]
|
|
|
|
|
- ``ParametricModel`` and the associated ``Parametric1DModel`` and
|
|
|
|
|
``Parametric2DModel`` classes have been renamed ``FittableModel``,
|
|
|
|
|
``Fittable1DModel``, and ``Fittable2DModel`` respectively. The base
|
|
|
|
|
``Model`` class has subsumed the functionality of the old
|
|
|
|
|
``ParametricModel`` class so that all models support parameter constraints.
|
|
|
|
|
The only distinction of ``FittableModel`` is that anything which subclasses
|
|
|
|
|
it is assumed "safe" to use with Astropy fitters. [#2276]
|
|
|
|
|
- ``NonLinearLSQFitter`` has been renamed ``LevMarLSQFitter`` to emphasise
|
|
|
|
|
that it uses the Levenberg-Marquardt optimization algorithm with a
|
|
|
|
|
least squares statistic function. [#1914]
|
|
|
|
|
- The ``SLSQPFitter`` class has been renamed ``SLSQPLSQFitter`` to emphasize
|
|
|
|
|
that it uses the Sequential Least Squares Programming optimization
|
|
|
|
|
algorithm with a least squares statistic function. [#1914]
|
|
|
|
|
- The ``Fitter.errorfunc`` method has been renamed to the more general
|
|
|
|
|
``Fitter.objective_function``. [#1914]
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
- Issue warning if unit is changed from a non-trivial value by directly
|
|
|
|
|
setting ``NDData.unit``. [#2411]
|
|
|
|
|
- The ``mask`` and ``flag`` attributes of ``astropy.nddata.NDData`` can now
|
|
|
|
|
be set with any array-like object instead of requiring that they be set
|
|
|
|
|
with a ``numpy.ndarray``. [#2419]
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
- Use of the ``astropy.sphinx`` module is deprecated; all new development of
|
|
|
|
|
this module is in ``astropy_helpers.sphinx`` which should be used instead
|
|
|
|
|
(therefore documentation builds that made use of any of the utilities in
|
|
|
|
|
``astropy.sphinx`` now have ``astropy_helpers`` as a documentation
|
|
|
|
|
dependency).
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
- The default table printing function now shows a table header row for units
|
|
|
|
|
if any columns have the unit attribute set. [#1282]
|
|
|
|
|
- Before, an unmasked ``Table`` was automatically converted to a masked
|
|
|
|
|
table if generated from a masked Table or a ``MaskedColumn``.
|
|
|
|
|
Now, this conversion is only done if explicitly requested or if any
|
|
|
|
|
of the input values is actually masked. [#1185]
|
|
|
|
|
- The repr() function of ``astropy.table.Table`` now shows the units
|
|
|
|
|
if any columns have the unit attribute set. [#2180]
|
|
|
|
|
- The semantics of the config options ``table.max_lines`` and
|
|
|
|
|
``table.max_width`` has changed slightly. If these values are not
|
|
|
|
|
set in the config file, astropy will try to determine the size
|
|
|
|
|
automatically from the terminal. [#2683]
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
- Correct use of UT in TDB calculation [#1938, #1939].
|
|
|
|
|
- ``TimeDelta`` objects can have scales other than TAI [#1932].
|
|
|
|
|
- Location information should now be passed on via an ``EarthLocation``
|
|
|
|
|
instance or anything that initialises it, e.g., a tuple containing
|
|
|
|
|
either geocentric or geodetic coordinates. [#1928]
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
- ``Quantity`` now converts input to float by default, as this is physically
|
|
|
|
|
most sensible for nearly all units [#1776].
|
|
|
|
|
- ``Quantity`` comparisons with ``==`` or ``!=`` now always return ``True``
|
|
|
|
|
or ``False``, even if units do not match (for which case a ``UnitsError``
|
|
|
|
|
used to be raised). [#2328]
|
|
|
|
|
- Applying ``float`` or ``int`` to a ``Quantity`` now works for all
|
|
|
|
|
dimensionless quantities; they are automatically converted to unscaled
|
|
|
|
|
dimensionless. [#2249]
|
|
|
|
|
- The exception ``astropy.units.UnitException``, which was
|
|
|
|
|
deprecated in astropy 0.2, has been removed. Use
|
|
|
|
|
``astropy.units.UnitError`` instead [#2386]
|
|
|
|
|
- Initializing a ``Quantity`` with a valid number/array with a ``unit``
|
|
|
|
|
attribute now interprets that attribute as the units of the input value.
|
|
|
|
|
This makes it possible to initialize a ``Quantity`` from an Astropy
|
|
|
|
|
``Table`` column and have it correctly pick up the units from the column.
|
|
|
|
|
[#2486]
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
- ``calcFootprint`` was deprecated. It is replaced by
|
|
|
|
|
``calc_footprint``. An optional boolean keyword ``center`` was
|
|
|
|
|
added to ``calc_footprint``. It controls whether the centers or
|
|
|
|
|
the corners of the pixels are used in the computation. [#2384]
|
|
|
|
|
- ``astropy.wcs.WCS.sip_pix2foc`` and
|
|
|
|
|
``astropy.wcs.WCS.sip_foc2pix`` formerly did not conform to the
|
|
|
|
|
``SIP`` standard: ``CRPIX`` was added to the ``foc`` result so
|
|
|
|
|
that it could be used as input to "core FITS WCS". As of astropy
|
|
|
|
|
0.4, ``CRPIX`` is no longer added to the result, so the ``foc``
|
|
|
|
|
space is correct as defined in the `SIP convention
|
|
|
|
|
<http://adsabs.harvard.edu/abs/2005ASPC..347..491S>`__. [#2360]
|
|
|
|
|
- ``astropy.wcs.UnitConverter``, which was deprecated in astropy
|
|
|
|
|
0.2, has been removed. Use the ``astropy.units`` module
|
|
|
|
|
instead. [#2386]
|
|
|
|
|
- The following methods on ``astropy.wcs.WCS``, which were
|
|
|
|
|
deprecated in astropy 0.1, have been removed [#2386]:
|
|
|
|
|
- ``all_pix2sky`` -> ``all_pix2world``
|
|
|
|
|
- ``wcs_pix2sky`` -> ``wcs_pix2world``
|
|
|
|
|
- ``wcs_sky2pix`` -> ``wcs_world2pix``
|
|
|
|
|
- The ``naxis1`` and ``naxis2`` attributes and the ``get_naxis``
|
|
|
|
|
method of ``astropy.wcs.WCS``, which were deprecated in astropy
|
|
|
|
|
0.2, have been removed. Use the shape of the underlying FITS data
|
|
|
|
|
array instead. [#2386]
|
|
|
|
|
- Misc
|
|
|
|
|
- The ``astropy.setup_helpers`` and ``astropy.version_helpers`` modules are
|
|
|
|
|
deprecated; any non-critical fixes and development to those modules should
|
|
|
|
|
be in ``astropy_helpers`` instead. Packages that use these modules in
|
|
|
|
|
their ``setup.py`` should depend on ``astropy_helpers`` following the same
|
|
|
|
|
pattern as in the Astropy package template.
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
- ``astropy.constants``
|
|
|
|
|
- ``astropy.constants.Contant`` objects can now be deep
|
|
|
|
|
copied. [#2601]
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
- The distance modulus function in ``astropy.cosmology`` can now handle
|
|
|
|
|
negative distances, which can occur in certain closed cosmologies. [#2008]
|
|
|
|
|
- Removed accidental imports of some extraneous variables in
|
|
|
|
|
``astropy.cosmology`` [#2025]
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
- ``astropy.io.ascii.read`` would fail to read lists of strings where some of
|
|
|
|
|
the strings consisted of just a newline ("\n"). [#2648]
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
- Use NaN for missing values in FITS when using Table.write for float
|
|
|
|
|
columns. Earlier the default fill value was close to 1e20.[#2186]
|
|
|
|
|
- Fixes for checksums on 32-bit platforms. Results may be different
|
|
|
|
|
if writing or checking checksums in "nonstandard" mode. [#2484]
|
|
|
|
|
- Additional minor bug fixes ported from PyFITS. [#2575]
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
- It is now possible to save an ``astropy.table.Table`` object as a
|
|
|
|
|
VOTable with any of the supported data formats, ``tabledata``,
|
|
|
|
|
``binary`` and ``binary2``, by using the ``tabledata_format``
|
|
|
|
|
kwarg. [#2138]
|
|
|
|
|
- Fixed a crash writing out variable length arrays. [#2577]
|
|
|
|
|
- ``astropy.nddata``
|
|
|
|
|
- Indexing ``NDData`` in a way that results in a single element returns that
|
|
|
|
|
element. [#2170]
|
|
|
|
|
- Change construction of result of arithmetic and unit conversion to allow
|
|
|
|
|
subclasses to require the presence of attribute like unit. [#2300]
|
|
|
|
|
- Scale uncertainties to correct units in arithmetic operations and unit
|
|
|
|
|
conversion. [#2393]
|
|
|
|
|
- Ensure uncertainty and mask members are copied in arithmetic and
|
|
|
|
|
convert_unit_to. [#2394]
|
|
|
|
|
- Mask result of arithmetic if either of the operands is masked. [#2403]
|
|
|
|
|
- Copy all attributes of input object if ``astropy.nddata.NDData`` is
|
|
|
|
|
initialized with an ``NDData`` object. [#2406]
|
|
|
|
|
- Copy ``flags`` to new object in ``convert_unit_to``. [#2409]
|
|
|
|
|
- Result of ``NDData`` arithmetic makes a copy of any WCS instead of using
|
|
|
|
|
a reference. [#2410]
|
|
|
|
|
- Fix unit handling for multiplication/division and use
|
|
|
|
|
``astropy.units.Quantity`` for units arithmetic. [#2413]
|
|
|
|
|
- A masked ``NDData`` is now converted to a masked array when used in an
|
|
|
|
|
operation or ufunc with a numpy array. [#2414]
|
|
|
|
|
- An unmasked ``NDData`` now uses an internal representation of its mask
|
|
|
|
|
state that ``numpy.ma`` expects so that an ``NDData`` behaves as an
|
|
|
|
|
unmasked array. [#2417]
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
- Fix crash in smart resolver when the resolution doesn't work. [#2591]
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
- The ``astropy.table.Column`` object can now use both functions and callable
|
|
|
|
|
objects as formats. [#2313]
|
|
|
|
|
- Fixed a problem on 64 bit windows that caused errors
|
|
|
|
|
"expected 'DTYPE_t' but got 'long long'" [#2490]
|
|
|
|
|
- Fix initialisation of ``TableColumns`` with lists or tuples. [#2647]
|
|
|
|
|
- Fix removal of single column using ``remove_columns``. [#2699]
|
|
|
|
|
- Fix a problem that setting a row element within a masked table did not
|
|
|
|
|
update the corresponding table element. [#2734]
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
- Correct UT1->UTC->UT1 round-trip being off by 1 second if UT1 is
|
|
|
|
|
on a leap second. [#2077]
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
- ``Quantity.copy`` now behaves identically to ``ndarray.copy``, and thus
|
|
|
|
|
supports the ``order`` argument (for numpy >=1.6). [#2284]
|
|
|
|
|
- Composing base units into identical composite units now works. [#2382]
|
|
|
|
|
- Creating and composing/decomposing units is now substantially faster [#2544]
|
|
|
|
|
- ``Quantity`` objects now are able to be assigned NaN [#2695]
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
- Astropy now requires wcslib version 4.23 or later. The version of
|
|
|
|
|
wcslib included with astropy has been updated to version 4.23.
|
|
|
|
|
- Bug fixes in the projection routines: in ``hpxx2s`` [the
|
|
|
|
|
cartesian-to-spherical operation of the ``HPX`` projection]
|
|
|
|
|
relating to bounds checking, bug introduced at wcslib 4.20; in
|
|
|
|
|
``parx2s`` and molx2s`` [the cartesion-to-spherical operation of
|
|
|
|
|
the ``PAR`` and ``MOL`` projections respectively] relating to
|
|
|
|
|
setting the stat vector; in ``hpxx2s`` relating to implementation
|
|
|
|
|
of the vector API; and in ``xphx2s`` relating to setting an
|
|
|
|
|
out-of-bounds value of *phi*.
|
|
|
|
|
- In the ``PCO`` projection, use alternative projection equations
|
|
|
|
|
for greater numerical precision near theta == 0. In the ``COP``
|
|
|
|
|
projection, return an exact result for theta at the poles.
|
|
|
|
|
Relaxed the tolerance for bounds checking a little in ``SFL``
|
|
|
|
|
projection.
|
|
|
|
|
- Fix a bug allocating insufficient memory in
|
|
|
|
|
``astropy.wcs.WCS.sub`` [#2468]
|
|
|
|
|
- A new method, ``Wcsprm.bounds_check`` (corresponding to wcslib's
|
|
|
|
|
``wcsbchk``) has been added to control what bounds checking is performed by
|
|
|
|
|
wcslib.
|
|
|
|
|
- ``WCS.to_header`` will now raise a more meaningful exception when the WCS
|
|
|
|
|
information is invalid or inconsistent in some way. [#1854]
|
|
|
|
|
- In ``WCS.to_header``, ``RESTFRQ`` and ``RESTWAV`` are no longer
|
|
|
|
|
rewritten if zero. [#2468]
|
|
|
|
|
- In ``WCS.to_header``, floating point values will now always be written
|
|
|
|
|
with an exponent or fractional part, i.e. ``.0`` being appended if necessary
|
|
|
|
|
to acheive this. [#2468]
|
|
|
|
|
- If the C extension for ``astropy.wcs`` was not built or fails to import for
|
|
|
|
|
any reason, ``import astropy.wcs`` will result in an ``ImportError``,
|
|
|
|
|
rather than getting obscure errors once the ``astropy.wcs`` is used.
|
|
|
|
|
[#2061]
|
|
|
|
|
- When the C extension for ``astropy.wcs`` is built using a version of
|
|
|
|
|
``wscslib`` already present in the system, the package does not try
|
|
|
|
|
to install ``wcslib`` headers under ``astropy/wcs/include``. [#2536]
|
|
|
|
|
- Fixes an unresolved external symbol error in the
|
|
|
|
|
`astropy.wcs._wcs` C extension on Microsoft Windows when built
|
|
|
|
|
with a Microsoft compiler. [#2478]
|
|
|
|
|
- Misc
|
|
|
|
|
- Running the test suite with ``python setup.py test`` now works if
|
|
|
|
|
the path to the source contains spaces. [#2488]
|
|
|
|
|
- The version of ERFA included with Astropy is now v1.1.0 [#2497]
|
|
|
|
|
- Removed deprecated option from travis configuration and force use of
|
|
|
|
|
wheels rather than allowing build from source. [#2576]
|
|
|
|
|
- The short option ``-n`` to run tests in parallel was broken
|
|
|
|
|
(conflicts with the distutils built-in option of "dry-run").
|
|
|
|
|
Changed to ``-j``. [#2566]
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
- ``python setup.py test --coverage`` will now give more accurate
|
|
|
|
|
results, because the coverage analysis will include early imports of
|
|
|
|
|
astropy. There doesn't seem to be a way to get this to work when
|
|
|
|
|
doing ``import astropy; astropy.test()``, so the ``coverage``
|
|
|
|
|
keyword to ``astropy.test`` has been removed. Coverage testing now
|
|
|
|
|
depends only on `coverage.py
|
|
|
|
|
<http://nedbatchelder.com/code/coverage/>`__, not
|
|
|
|
|
``pytest-cov``. [#2112]
|
|
|
|
|
- The included version of py.test has been upgraded to 2.5.1. [#1970]
|
|
|
|
|
- The included version of six.py has been upgraded to 1.5.2. [#2006]
|
|
|
|
|
- Where appropriate, tests are now run both with and without the
|
|
|
|
|
``unicode_literals`` option to ensure that we support both cases. [#1962]
|
|
|
|
|
- Running the Astropy test suite from within the IPython REPL is disabled for
|
|
|
|
|
now due to bad interaction between the test runner and IPython's logging
|
|
|
|
|
and I/O handler. For now, run the Astropy tests should be run in the basic
|
|
|
|
|
Python interpreter. [#2684]
|
|
|
|
|
- Added support for numerical comparison of floating point values appearing in
|
|
|
|
|
the output of doctests using a ``+FLOAT_CMP`` doctest flag. [#2087]
|
|
|
|
|
- A monkey patch is performed to fix a bug in Numpy version 1.7 and
|
|
|
|
|
earlier where unicode fill values on masked arrays are not
|
|
|
|
|
supported. This may cause unintended side effects if your
|
|
|
|
|
application also monkey patches ``numpy.ma`` or relies on the broken
|
|
|
|
|
behavior. If unicode support of masked arrays is important to your
|
|
|
|
|
application, upgrade to Numpy 1.8 or later for best results. [#2059]
|
|
|
|
|
- The developer documentation has been extensively rearranged and
|
|
|
|
|
rewritten. [#1712]
|
|
|
|
|
- The ``human_time`` function in ``astropy.utils`` now returns strings
|
|
|
|
|
without zero padding. [#2420]
|
|
|
|
|
- The ``bdist_dmg`` command for ``setup.py`` has now been removed. [#2553]
|
|
|
|
|
- Many broken API links have been fixed in the documentation, and the
|
|
|
|
|
``nitpick`` Sphinx option is now used to avoid broken links in future.

- Update to 0.3.2 (2014-05-13)
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
- if ``sep`` argument is specified to be a single character in
|
|
|
|
|
``sexagisimal_to_string``, it now includes seperators only between
|
|
|
|
|
items [#2183]
|
|
|
|
|
- Ensure comparisons involving ``Distance`` objects do not raise exceptions;
|
|
|
|
|
also ensure operations that lead to units other than length return
|
|
|
|
|
``Quantity``. [#2206, #2250]
|
|
|
|
|
- Multiplication and division of ``Angle`` objects is now
|
|
|
|
|
supported. [#2273]
|
|
|
|
|
- Fixed ``Angle.to_string`` functionality so that negative angles have the
|
|
|
|
|
correct amount of padding when ``pad=True``. [#2337]
|
|
|
|
|
- Mixing strings and quantities in the ``Angle`` constructor now
|
|
|
|
|
works. For example: ``Angle(['1d', 1. * u.d])``. [#2398]
|
|
|
|
|
- If ``Longitude`` is given a ``Longitude`` as input, use its ``wrap_angle``
|
|
|
|
|
by default [#2705]
|
|
|
|
|
- ``astropy.cosmology``
|
|
|
|
|
- Fixed ``format()`` compatibility with Python 2.6. [#2129]
|
|
|
|
|
- Be more careful about converting to floating point internally [#1815, #1818]
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
- The CDS reader in ``astropy.io.ascii`` can now handle multiple
|
|
|
|
|
description lines in ReadMe files. [#2225]
|
|
|
|
|
- When reading a table with values that generate an overflow error during
|
|
|
|
|
type conversion (e.g. overflowing the native C long type), fall through to
|
|
|
|
|
using string. Previously this generated an exception [#2234].
|
|
|
|
|
- Some CDS files mark missing values with ``"---"``, others with ``"--"``.
|
|
|
|
|
Recognize any string with one to four dashes as null value. [#1335]
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
- Allow pickling of ``FITS_rec`` objects. [#1597]
|
|
|
|
|
- Improved behavior when writing large compressed images on OSX by removing
|
|
|
|
|
an unncessary check for platform architecture. [#2345]
|
|
|
|
|
- Fixed an issue where Astropy ``Table`` objects containing boolean columns
|
|
|
|
|
were not correctly written out to FITS files. [#1953]
|
|
|
|
|
- Several other bug fixes ported from PyFITS v3.2.3 [#2368]
|
|
|
|
|
- Fixed a crash on Python 2.x when writing a FITS file directly to a
|
|
|
|
|
``StringIO.StringIO`` object. [#2463]
|
|
|
|
|
- ``astropy.io.registry``
|
|
|
|
|
- Allow readers/writers with the same name to be attached to different
|
|
|
|
|
classes. [#2312]
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
- By default, floating point values are now written out using
|
|
|
|
|
``repr`` rather than ``str`` to preserve precision [#2137]
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
- Fixed the ``SIP`` and ``InverseSIP`` models both so that they work in the
|
|
|
|
|
first place, and so that they return results consistent with the SIP
|
|
|
|
|
functions in ``astropy.wcs``. [#2177]
|
|
|
|
|
- ``astropy.stats``
|
|
|
|
|
- Ensure the ``axis`` keyword in ``astropy.stats.funcs`` can now be used for
|
|
|
|
|
all axes. [#2173]
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
- Ensure nameless columns can be printed, using 'None' for the header. [#2213]
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
- Fixed pickling of ``Time`` objects. [#2123]
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
- ``Quantity._repr_latex_()`` returns ``NotImplementedError`` for quantity
|
|
|
|
|
arrays instead of an uninformative formatting exception. [#2258]
|
|
|
|
|
- Ensure ``Quantity.flat`` always returns ``Quantity``. [#2251]
|
|
|
|
|
- Angstrom unit renders better in MathJax [#2286]
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
- Progress bars will now be displayed inside the IPython
|
|
|
|
|
qtconsole. [#2230]
|
|
|
|
|
- ``data.download_file()`` now evaluates ``REMOTE_TIMEOUT()`` at runtime
|
|
|
|
|
rather than import time. Previously, setting ``REMOTE_TIMEOUT`` after
|
|
|
|
|
import had no effect on the function's behavior. [#2302]
|
|
|
|
|
- Progressbar will be limited to 100% so that the bar does not exceed the
|
|
|
|
|
terminal width. The numerical display can still exceed 100%, however.
|
|
|
|
|
- ``astropy.vo``
|
|
|
|
|
- Fixed ``format()`` compatibility with Python 2.6. [#2129]
|
|
|
|
|
- Cone Search validation no longer raises ``ConeSearchError`` for positive RA.
|
|
|
|
|
[#2240, #2242]
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
- Fixed a bug where calling ``astropy.wcs.Wcsprm.sub`` with
|
|
|
|
|
``WCSSUB_CELESTIAL`` may cause memory corruption due to
|
|
|
|
|
underallocation of a temporary buffer. [#2350]
|
|
|
|
|
- Fixed a memory allocation bug in ``astropy.wcs.Wcsprm.sub`` and
|
|
|
|
|
``astropy.wcs.Wcsprm.copy``. [#2439]
|
|
|
|
|
- Misc
|
|
|
|
|
- Fixes for compatibility with Python 3.4. [#1945]
|
|
|
|
|
- ``import astropy; astropy.test()`` now correctly uses the same test
|
|
|
|
|
configuration as ``python setup.py test`` [#1811]
|
|
|
|
|
- Update to 0.3.1 (2014-03-04)
|
|
|
|
|
* Bug Fixes
|
|
|
|
|
- ``astropy.config``
|
|
|
|
|
- Fixed a bug where ``ConfigurationItem.set_temp()`` does not reset to
|
|
|
|
|
default value when exception is raised within ``with`` block. [#2117]
|
|
|
|
|
- ``astropy.convolution``
|
|
|
|
|
- Fixed a bug where ``_truncation`` was left undefined for ``CustomKernel``.
|
|
|
|
|
[#2016]
|
|
|
|
|
- Fixed a bug with ``_normalization`` when ``CustomKernel`` input array
|
|
|
|
|
sums to zero. [#2016]
|
|
|
|
|
- ``astropy.coordinates``
|
|
|
|
|
- Fixed a bug where using ``==`` on two array coordinates wouldn't
|
|
|
|
|
work. [#1832]
|
|
|
|
|
- Fixed bug which caused ``len()`` not to work for coordinate objects and
|
|
|
|
|
added a ``.shape`` property to get appropriately array-like behavior.
|
|
|
|
|
[#1761, #2014]
|
|
|
|
|
- Fixed a bug where sexagesimal notation would sometimes include
|
|
|
|
|
exponential notation in the last field. [#1908, #1913]
|
|
|
|
|
- ``CompositeStaticMatrixTransform`` no longer attempts to reference the
|
|
|
|
|
undefined variable ``self.matrix`` during instantiation. [#1944]
|
|
|
|
|
- Fixed pickling of ``Longitude``, ensuring ``wrap_angle`` is preserved
|
|
|
|
|
[#1961]
|
|
|
|
|
- Allow ``sep`` argument in ``Angle.to_string`` to be empty (resulting in no
|
|
|
|
|
separators) [#1989]
|
|
|
|
|
- ``astropy.io.ascii``
|
|
|
|
|
- Allow passing unicode delimiters when reading or writing tables. The
|
|
|
|
|
delimiter must be convertible to pure ASCII. [#1949]
|
|
|
|
|
- Fix a problem when reading a table and renaming the columns to names that
|
|
|
|
|
already exist. [#1991]
|
|
|
|
|
- ``astropy.io.fits``
|
|
|
|
|
- Ported all bug fixes from PyFITS 3.2.1. See the PyFITS changelog at
|
|
|
|
|
http://pyfits.readthedocs.org/en/v3.2.1/ [#2056]
|
|
|
|
|
- ``astropy.io.misc``
|
|
|
|
|
- Fixed issues in the HDF5 Table reader/writer functions that occurred on
|
|
|
|
|
Windows. [#2099]
|
|
|
|
|
- ``astropy.io.votable``
|
|
|
|
|
- The ``write_null_values`` kwarg to ``VOTable.to_xml``, when set to `False`
|
|
|
|
|
(the default) would produce non-standard VOTable files. Therefore, this
|
|
|
|
|
functionality has been replaced by a better understanding that knows which
|
|
|
|
|
fields in a VOTable may be left empty (only ``char``, ``float`` and
|
|
|
|
|
``double`` in VOTable 1.1 and 1.2, and all fields in VOTable 1.3). The
|
|
|
|
|
kwarg is still accepted but it will be ignored, and a warning is emitted.
|
|
|
|
|
[#1809]
|
|
|
|
|
- Printing out a ``astropy.io.votable.tree.Table`` object using `repr` or
|
|
|
|
|
`str` now uses the pretty formatting in ``astropy.table``, so it's possible
|
|
|
|
|
to easily preview the contents of a ``VOTable``. [#1766]
|
|
|
|
|
- ``astropy.modeling``
|
|
|
|
|
- Fixed bug in computation of model derivatives in ``LinearLSQFitter``.
|
|
|
|
|
[#1903]
|
|
|
|
|
- Raise a ``NotImplementedError`` when fitting composite models. [#1915]
|
|
|
|
|
- Fixed bug in the computation of the ``Gaussian2D`` model. [#2038]
|
|
|
|
|
- Fixed bug in the computation of the ``AiryDisk2D`` model. [#2093]
|
|
|
|
|
- ``astropy.sphinx``
|
|
|
|
|
- Added slightly more useful debug info for AstropyAutosummary. [#2024]
|
|
|
|
|
- ``astropy.table``
|
|
|
|
|
- The column string representation for n-dimensional cells with only
|
|
|
|
|
one element has been fixed. [#1522]
|
|
|
|
|
- Fix a problem that caused ``MaskedColumn.__getitem__`` to not preserve
|
|
|
|
|
column metadata. [#1471, #1872]
|
|
|
|
|
- With Numpy prior to version 1.6.2, tables with Unicode columns now
|
|
|
|
|
sort correctly. [#1867]
|
|
|
|
|
- ``astropy.table`` can now print out tables with Unicode columns containing
|
|
|
|
|
non-ascii characters. [#1864]
|
|
|
|
|
- Columns can now be named with Unicode strings, as long as they contain only
|
|
|
|
|
ascii characters. This makes using ``astropy.table`` easier on Python 2
|
|
|
|
|
when ``from __future__ import unicode_literals`` is used. [#1864]
|
|
|
|
|
- Allow pickling of ``Table``, ``Column``, and ``MaskedColumn`` objects. [#792]
|
|
|
|
|
- Fix a problem where it was not possible to rename columns after sorting or
|
|
|
|
|
adding a row. [#2039]
|
|
|
|
|
- ``astropy.time``
|
|
|
|
|
- Fix a problem where scale conversion problem in TimeFromEpoch
|
|
|
|
|
was not showing a useful error [#2046]
|
|
|
|
|
- Fix a problem when converting to one of the formats ``unix``, ``cxcsec``,
|
|
|
|
|
``gps`` or ``plot_date`` when the time scale is ``UT1``, ``TDB`` or ``TCB``
|
|
|
|
|
[#1732]
|
|
|
|
|
- Ensure that ``delta_ut1_utc`` gets calculated when accessed directly,
|
|
|
|
|
instead of failing and giving a rather obscure error message [#1925]
|
|
|
|
|
- Fix a bug when computing the TDB to TT offset. The transform routine was
|
|
|
|
|
using meters instead of kilometers for the Earth vector. [#1929]
|
|
|
|
|
- Increase ``__array_priority__`` so that ``TimeDelta`` can convert itself
|
|
|
|
|
to a ``Quantity`` also in reverse operations [#1940]
|
|
|
|
|
- Correct hop list from TCG to TDB to ensure that conversion is
|
|
|
|
|
possible [#2074]
|
|
|
|
|
- ``astropy.units``
|
|
|
|
|
- ``Quantity`` initialisation rewritten for speed [#1775]
|
|
|
|
|
- Fixed minor string formatting issue for dimensionless quantities. [#1772]
|
|
|
|
|
- Fix error for inplace operations on non-contiguous quantities [#1834].
|
|
|
|
|
- The definition of the unit ``bar`` has been corrected to "1e5
|
|
|
|
|
Pascal" from "100 Pascal" [#1910]
|
|
|
|
|
- For units that are close to known units, but not quite, for
|
|
|
|
|
example due to differences in case, the exception will now include
|
|
|
|
|
recommendations. [#1870]
|
|
|
|
|
- The generic and FITS unit parsers now accept multiple slashes in
|
|
|
|
|
the unit string. There are multiple ways to interpret them, but
|
|
|
|
|
the approach taken here is to convert "m/s/kg" to "m s-1 kg-1".
|
|
|
|
|
Multiple slashes are accepted, but discouraged, by the FITS
|
|
|
|
|
standard, due to the ambiguity of parsing, so a warning is raised
|
|
|
|
|
when it is encountered. [#1911]
|
|
|
|
|
- The use of "angstrom" (with a lower case "a") is now accepted in FITS unit
|
|
|
|
|
strings, since it is in common usage. However, since it is not officially
|
|
|
|
|
part of the FITS standard, a warning will be issued when it is encountered.
|
|
|
|
|
[#1911]
|
|
|
|
|
- Pickling unrecognized units will not raise a ``AttributeError``. [#2047]
|
|
|
|
|
- ``astropy.units`` now correctly preserves the precision of
|
|
|
|
|
fractional powers. [#2070]
|
|
|
|
|
- If a ``Unit`` or ``Quantity`` is raised to a floating point power
|
|
|
|
|
that is very close to a rational number with a denominator less
|
|
|
|
|
than or equal to 10, it is converted to a ``Fraction`` object to
|
|
|
|
|
preserve its precision through complex unit conversion operations.
|
|
|
|
|
[#2070]
|
|
|
|
|
- ``astropy.utils``
|
|
|
|
|
- Fixed crash in ``timer.RunTimePredictor.do_fit``. [#1905]
|
|
|
|
|
- Fixed ``astropy.utils.compat.argparse`` for Python 3.1. [#2017]
|
|
|
|
|
- ``astropy.wcs``
|
|
|
|
|
- ``astropy.wcs.WCS``, ``astropy.wcs.WCS.fix`` and
|
|
|
|
|
``astropy.wcs.find_all_wcs`` now have a ``translate_units`` keyword
|
|
|
|
|
argument that is passed down to ``astropy.wcs.Wcsprm.fix``. This can be
|
|
|
|
|
used to specify any unsafe translations of units from rarely used ones to
|
|
|
|
|
more commonly used ones.
|
|
|
|
|
Although ``"S"`` is commonly used to represent seconds, its translation to
|
|
|
|
|
``"s"`` is potentially unsafe since the standard recognizes ``"S"``
|
|
|
|
|
formally as Siemens, however rarely that may be used. The same applies to
|
|
|
|
|
``"H"`` for hours (Henry), and ``"D"`` for days (Debye).
|
|
|
|
|
When these sorts of changes are performed, a warning is emitted.
|
|
|
|
|
[#1854]
|
|
|
|
|
- When a unit is "fixed" by ``astropy.wcs.WCS.fix`` or
|
|
|
|
|
``astropy.wcs.Wcsprm.unitfix``, it now correctly reports the ``CUNIT``
|
|
|
|
|
field that was changed. [#1854]
|
|
|
|
|
- ``astropy.wcs.Wcs.printwcs`` will no longer warn that ``cdelt`` is being
|
|
|
|
|
ignored when none was present in the FITS file. [#1845]
|
|
|
|
|
- ``astropy.wcs.Wcsprm.set`` is called from within the ``astropy.wcs.WCS``
|
|
|
|
|
constructor, therefore any invalid information in the keywords will be
|
|
|
|
|
raised from the constructor, rather than on a subsequent call to a
|
|
|
|
|
transformation method. [#1918]
|
|
|
|
|
- Fix a memory corruption bug when using ``astropy.wcs.Wcs.sub`` with
|
|
|
|
|
``astropy.wcs.WCSSUB_CELESTIAL``. [#1960]
|
|
|
|
|
- Fixed the ``AttributeError`` exception that was raised when using
|
|
|
|
|
``astropy.wcs.WCS.footprint_to_file``. [#1912]
|
|
|
|
|
- Fixed a ``NameError`` exception that was raised when using
|
|
|
|
|
``astropy.wcs.validate`` or the ``wcslint`` script. [#2053]
|
|
|
|
|
- Fixed a bug where named WCSes may be erroneously reported as ``' '`` when
|
|
|
|
|
using ``astropy.wcs.validate`` or the ``wcslint`` script. [#2053]
|
|
|
|
|
- Fixed a bug where error messages about incorrect header keywords
|
|
|
|
|
may not be propagated correctly, resulting in a "NULL error object
|
|
|
|
|
in wcslib" message. [#2106]
|
|
|
|
|
- Misc
|
|
|
|
|
- There are a number of improvements to make Astropy work better on big
|
|
|
|
|
endian platforms, such as MIPS, PPC, s390x and SPARC. [#1849]
|
|
|
|
|
- The test suite will now raise exceptions when a deprecated feature of
|
|
|
|
|
Python or Numpy is used. [#1948]
|
|
|
|
|
* Other Changes and Additions
|
|
|
|
|
- A new function, ``astropy.wcs.get_include``, has been added to get the
|
|
|
|
|
location of the ``astropy.wcs`` C header files. [#1755]
|
|
|
|
|
- The doctests in the ``.rst`` files in the ``docs`` folder are now
|
|
|
|
|
tested along with the other unit tests. This is in addition to the
|
|
|
|
|
testing of doctests in docstrings that was already being performed.
|
|
|
|
|
See ``docs/development/testguide.rst`` for more information. [#1771]
|
|
|
|
|
- Fix a problem where import fails on Python 3 if setup.py exists
|
|
|
|
|
in current directory. [#1877]
