Accepting request 1171972 from home:bnavigator:branches:devel:languages:python:numeric - Update to 6.1.0 ## Highlights * Updated minimum Python version to 3.10 * Order-dependent angular separations now come with warnings * io.ascii uses 64-integers by default for integer columns * Changes to semantics of copy= keyword arguments * Cosmology is now a dataclass() ## New Features ### astropy.coordinates * BaseCoordinateFrame now has a position_angle() method, which is the same as the position_angle method of SkyCoord instances. [#15737] * By default the SkyCoord and BaseCoordinateFrame separation() methods now emit a warning if they have to perform a coordinate transformation that is not a pure rotation to inform the user that the angular separation can depend on the direction of the transformation. It is possible to modify this behaviour with the new optional keyword-only origin_mismatch argument. Specifying origin_mismatch="ignore" allows any transformation to succeed without warning, which has been the behaviour so far. origin_mismatch="error" forbids all transformations that are not pure rotations. [#16246] ### astropy.io.ascii * Clearer error message in reading ASCII tables when there is a mismatch between converter type and column type. [#15991] ### astropy.io.registry * The module astropy.io.typing has been added to provide type annotations for I/O-related functionality. [#15916] ### astropy.samp * SAMP web profile CORS HTTP server implements Private Network Access proposal. [#16193] ### astropy.table * Table now has a setdefault() method, analogous to dict.setdefault(). [#16188] ### astropy.units * Added a new module astropy.units.typing that provides support for type annotations related to astropy.units. [#15860] * Added a new CGS unit Oersted. [#15962] * Added “surface brightness”, “surface brightness wav”, “photon surface brightness”, and “photon surface brightness wav” to recognized physical types. [#16032] * Added magnetic helicity as a physical type. [#16101] ### astropy.utils * For gufuncs on Masked instances, add support for the axes argument. [#16121] * Masked instances now support the various numpy array set operations, such as np.unique and np.isin. [#16224] ### astropy.wcs * Added support for slicing WCS objects containing cpdis or det2im distortions, which previously were ignored. [#16163] ## API Changes ### astropy.coordinates * The astropy.coordinates.transformations module has been refactored into a module. There should be no user-visible changes, but if you notice any, please open an Issue. [#15895] * Changed the default value of the copy argument in astropy.coordinates.representation.CylindricalDifferential.__init__ from False to True, which is the intended behaviour for all subclasses of astropy.coordinates.representation.BaseDifferential. [#16198] ### astropy.cosmology * Cosmology and its subclasses are now frozen dataclass objects. [#15484] * The argument verbose in the function z_at_value is now keyword-only. [#15855] ### astropy.io.ascii * The io.ascii Python and C table readers were updated to use a 64-bit integer field by default when reading a column of integer numeric data. This changes the default behavior on Windows and potentially 32-bit architectures. Previously on those platforms, table columns with any long integers which overflowed the 32-bit integer would be returned as string columns. The new default behavior is consistent with numpy v2 and pandas. [#16005] * The parallel fast-reader parser for reading ASCII files has been removed. Since astropy v4.0.4 requesting this option has issued a warning that this option is broken and that the serial parser will be used. The parallel key in the fast_reader argument for reading ASCII tables is no longer available. [#16103] ### astropy.table * show_in_notebook is deprecated and it is recommended to use dedicated tools in the Jupyter ecosystem to create interactive plots in notebooks. [#15905] * A warning is now emitted when Quantity values are inserted into empty Column objects via Table.insert_row or Table.add_row. [#16038] * show_in_browser is deprecated (pending feedback from the community). Please use astropy/astropy#16067 if you are actively using the function. [#16068] * TableColumns.setdefault() and TableColumns.update() methods (which would typically be called as Table.columns.setdefault() and Table.columns.update()) have been deprecated because they can easily corrupt the Table instance the TableColumns instance is attached to. The Table.setdefault() and Table.update() methods are safe. [#16154] ### astropy.time * TIME_FORMATS and TIME_DELTA_FORMATS in astropy.time.formats are changed from OrderedDict to Python dict. [#15491] * A FutureWarning is now emitted when mutating Time.location post-initialization. [#16063] * Following the removal of np.ndarray.ptp in Numpy v2, Time.ptp is now deprecated in favor of np.ptp. [#16212] ### astropy.units * If any iterable such as a list of tuple was input to Quantity, a check was done to see if they contained only quantities, and, if so, the quantities were concatenated. This makes sense for list and tuple, but is not necessarily logical for all iterables and indeed was broken for those that do not have a length (such as array_api array instances). Hence, the check will now be done only for values where it makes sense, i.e., instances of list and tuple. [#15752] * Units now exposes get_converter which returns a function that will convert a scalar or array from one unit to another. This can be useful to speed up code that converts many quantities with the same unit to another one, especially if the quantity has not many elements, so that the overhead of creating a conversion function is relatively large. [#16139] ### astropy.utils * Deprecate importing ErfaError and ErfaWarning from astropy.utils.exceptions. They should be imported directly from erfa instead. [#15777] * introspection.isinstancemethod() and introspection.find_mod_objs() are deprecated. [#15934] * astropy.utils.console.terminal_size is now deprecated in favour of shutil.get_terminal_size from the standard library. [#16045] * indent() is deprecated. Use textwrap.indent() from Python standard library instead. [#16223] * Unmasked Masked scalar instances are now considered hashable, to match the implicit behaviour of regular arrays, where if an operation leads to a scalar, a hashable array scalar is returned. [#16224] ### astropy.visualization * Renamed the min_cut and max_cut keywords in simple_norm and fits2bitmap to vmin and vmax. The old names are deprecated. [#15621] * If vmin == vmax, the ImageNormalize class now maps the input data to 0. If vmin > vmax, the ImageNormalize class now raises a ValueError. [#15622] ## Bug Fixes ### astropy.convolution * Avoid a segfault when calling astropy.convolution.convolve on an empty array. An exception is now raised instead. [#15840] ### astropy.coordinates * Previously passing a SkyCoord instance to the BaseCoordinateFrame separation() or separation_3d() methods could produce wrong results, depending on what additional frame attributes were defined on the SkyCoord, but now SkyCoord input can be used safely. [#15659] * Distance now accepts as parallax any angle-like value. This includes types like Column which have a unit but are not Quantity subclasses. [#15712] * The new default for the class method SkyCoord.from_name() is to look for coordinates first in SIMBAD, then in NED, and then in VizieR, instead of having no specific order. [#16046] * Fix Angle.to_string() for angles in degrees represented in ‘hms’ and angles in hours represented in ‘dms’. [#16085] * Fix a bug where SkyCoord.spherical_offsets_by would crash when a wrap was needed. [#16241] * search_around_3d() now always raises a UnitConversionError if the units of the distances in coord1 and coord2 and the unit of distlimit do not agree. Previously the error was not raised if at least one of the coordinates was empty. [#16280] ### astropy.cosmology * Fixed a bug where the attribute ParametersAttribute.attr_name could be None instead of a string. [#15882] ### astropy.io.ascii * Reading of CDS header files with multi-line descriptions where the continued line started with a number was broken. This is now fixed. [#15617] * Ensure that the names of mixin columns are properly propagated as labels for the MRT format. [#15848] * Fixed reading IPAC tables for long column type on some platforms, e.g., Windows. [#16005] ### astropy.io.fits * Avoid WinError 1455 in opening some large files with memory mapping on windows. [#15388] * Fix TDISP parsing for floating numbers. [#16007] * Fix a crash when calling FITS writeto methods with stdout as the output stream. [#16008] * Fix TDISP parsing for floating numbers in formats ES / EN. [#16015] * Fix conversion of Table to BinTableHDU with character_as_bytes=True. [#16358] * Improved error message when instantiating a fits table with an ill-formed array. [#16363] ### astropy.io.misc * Reading an empty table stored in parquet format now creates an empty table instead of raising an unexpected error. [#16237] ### astropy.io.votable * When reading a VOTable, if some user-requested columns were not present then the resulting error message previously listed all the requested column names. Now only columns that are actually missing are shown. [#15956] ### astropy.stats * Fix a spurious warning when calling sigma_clipped_stats on a MaskedColumn. [#15844] ### astropy.table * Fix a Table bug when setting items (via slice or index list) in a bytes type MaskedColumn would cause the column mask to be set to all False. A common way to trigger this bug was reading a FITS file with masked string data and then sorting the table. [#15669] * Fix slicing logic for Row. Previously, slicing a astropy.table.row.Row object would incorrectly return a column, now it correctly returns a list of values from that row. [#15733] * Fix a ValueError raised by table.join when fed with large tables. This would typically happen in situations when the result joined table would be too large to fit in memory. In those situations, the error message is now much more clearly about the necessary memory size. [#15734] * Fix an unintended exception being raised when attempting to compare two unequal Table instances. [#15845] * Ensure that if a Column is initialized with a Quantity it will use by default a possible name defined on the quantity’s .info. [#15848] * Fix a bug where columns with dtype=object wouldn’t be properly deep-copied using copy.deepcopy. [#15871] * Fix hasattr(Table, "iloc") raising an exception, preventing use of tables e.g. with scikit-learn. [#15913] * Calling Table.group_by on an empty table no longer raises an exception. [#16093] * The unit conversion convert_unit_to with MaskedColumn was broken as it was storing the old unit in a dictionary attached to underlying np.ma.MaskedArray. This fixes it by overwriting the old unit after unit conversion. [#16118] * astropy.table.vstack will no longer modify the input list even when it contains non-Table objects like astropy.table.Row. [#16130] * Update old dataTables.js version. This should not affect the end user. [#16315] ### astropy.time * Fix comparing NaN Quantity with TimeDelta object. [#15830] * Scalar Time instances are now hashable if they are not masked, also if one uses Masked internally, matching the behaviour prior to astropy 6.0 (and the current behaviour when masking using np.ma.MaskedArray). [#16224] ### astropy.units * Fix rare signature incompatibilities between helper and helped array functions. Most involve cases where the corresponding numpy function has had its arguments renamed between numpy versions. Since all those generally changed the first arguments, which are typically passed as positional arguments, this should not affect user code. Affected functions: - numpy.array_str - numpy.choose - numpy.convolve - numpy.correlate - numpy.histogram - numpy.histogramdd - numpy.histogram2d - numpy.isin - numpy.inner - numpy.nanmedian - numpy.unique - numpy.matrix_rank - numpy.unwrap - numpy.vdot - numpy.lib.recfunctions.unstructured_to_structured [#15710] * Fix an issue with unicode string representations of units shown as superscripts (like degree) when raised to some power. Like for LaTeX representations, now the superscript unicode character is replaced by the literal short name before adding the power. [#15755] * Fix a missing Sun unit in the list of VOUnits simple_units. [#15832] * Fix an unhelpful TypeError when attempting truediv, lshift (<<) or mul () or truediv (/) with a Unit for right operand and a numpy array with non-numerical dtype for left operand. [#15883] Fix write/read roundtrips with empty Table dumped to ECSV. [#15885] * Fix a bug where LaTeX formatter would return empty strings for unity (1) input. [#15923] * Fix extraneous space in LaTeX repr for Quantity objects with superscript units (e.g. angles or temperatures in degree Celsius). [#16043] * Ensure powers of units are consistently as simple as possible. So, an integer if possible, otherwise a float, or a fraction if the float is really close to that. This also ensures the hash of a unit is unique for any given unit (previously, the same power could be represented as float, int or fraction, which made the hash different). [#16058] * Ensure that find_equivalent_units only returns actual units, not units that raised to some power match the requested one. With this fix, (u.m*-3).find_equivalent_units() properly finds nothing, rather than all units of length. [#16127] Using a dimensionless Quantity as an exponent works anew. In astropy 6.0.1 an exception was erroneously raised. [#16261] ### astropy.utils * Fix rare signature incompatibilities between helper and helped array functions. These typically cover corner cases and should not affect user code. Some arguments weren’t being re-exposed correctly or at all, depending on numpy’s version. Affected functions: - numpy.broadcast_arrays - numpy.median - numpy.quantile - numpy.empty_like - numpy.ones_like - numpy.zeros_like - numpy.full_like [#16025] * Fix a bug where astropy.utils.console.Spinner would leak newlines for messages longer than terminal width. [#16040] * Update report_diff_values so the diff no longer depends on the console terminal size. [#16065] * Fix support in Masked for generalized ufuncs with more than a single core dimension (such as erfa.rxp). [#16120] * Masked array instances now deal more properly with structured dtypes, combining field masks to get element masks for generalized ufuncs, and allowing .view() any time the mask can be viewed as well. This allows a larger number of erfa routines to work with masked data. [#16125] ### astropy.visualization * WCSAxes will correctly set certain defaults when wcs.world_axis_physical_types contains custom: prefixes. [#15626] * Fix an edge case where quantity_support would produce duplicate tick labels for small data ranges. [#15841] * Fix a bug where AngleFormatterLocator and ScalarFormatterLocator wouldn’t respect matplotlib.rc’s axes.unicode_minus parameter. [#15902] * Fixed a bug in CoordinateHelper.grid method to properly handle draw_grid=False and draw_grid=None, ensuring grid lines are controlled correctly even when not explicitly called. [#15985] ### astropy.wcs * Updated bundled WCSLIB version to 8.2.2. This update fixes character buffer overflows in the comment string for the longitude and latitude axes triggered by some projections in wcshdo(), and also the formatting for generic coordinate systems. For a full list of changes - see http://www.atnf.csiro.au/people/mcalabre/WCS/CHANGES or astropy/cextern/wcslib/CHANGES [#15795] * Fixed a bug in fit_wcs_from_points that does not set the default value of the cdelt of the returned WCS object. [#16027] * Fixed a bug in DistortionLookupTable (which implements cpdis and det2im projection corrections to a WCS) in which image pixels received an incorrect distortion value, from a location in the lookup table incorrectly offset by about 1 table pixel. [#16163] ## Other Changes and Additions * Update minimum supported Python version to 3.10 [#15603] * The minimum required NumPy version is now 1.23 and the minimum required SciPy version is 1.8. [#15706] * Fix loading parser tabs on pyc-only installations. * Fix a bug in the wrappers for the lex and yacc wrappers that are used for parsing Astropy units so that they work on pyc-only installations. * According to the Python module loading flow chart, when evaluating import foo and foo.py is not found, Python then reads foo.pyc. * One can take advantage of this fact to strip source files and leave only Python bytecode files for deployment inspace-constrained execution environments such as AWS Lambda. Astropy is now compatible with pyc-only deployments. [#16159] * Change the default value of copy arguments in public APIs from False to None if Numpy 2.0 or newer is installed.
