Full Changelog: v2.1.0...v2.1.1

v2.1.0

v2.1.0 (2023-03-01)

Backwards Incompatible Changes

• To support compatibility with reproject 0.9, the API of .NDCube.reproject_to has been tweaked so
  that any keyword argument to the underlying reprojection function
  can be passed through. This has the effect of being a breaking
  change if you were specifying any arguments after shape_out= as
  positional rather than keyword arguments. (Note that in a future
  release we will probably change to require keyword arguments to
  reproject_to. (#552)

Features

• Implement new property, ndcube.ExtraCoords.is_empty that returns
  True if the object has got extra coords. Otherwise return False.
  (#450)
• Add ndcube.ExtraCoords.resample
  method to resample extra coordinates by a certain factor in each
  array dimension. (#450)
• Implement a new ndcube.NDCube.rebin
  method to combine integer numbers of pixels along each axis into
  larger pixels. (#450)
• Add new methods to interpolate lookup table coordinates: ndcube.extra_coords.table_coord.QuantityTableCoordinate.interpolate,
  ndcube.extra_coords.table_coord.SkyCoordTableCoordinate.interpolate,
  ndcube.extra_coords.table_coord.TimeTableCoordinate.interpolate,
  ndcube.extra_coords.table_coord.MultipleTableCoordinate.interpolate
  (#450)
• Add ndcube.NDCubeSequence.crop and
  ndcube.NDCubeSequence.crop_by_values
  methods which crop the ~ndcube.NDCubeSequence based on input world
  coordinate ranges.
  (#466)
• Add basic arithmetic methods between ~ndcube.NDCube objects and broadcastable
  arrays, scalars, and ~astropy.unit.Quantity objects. Operations
  between two ~ndcube.NDCube objects
  are not supported.
  (#541)
• Add ndcube.NDCube.to to convert cube
  to new unit. (#586)
• Created ~ndcube.GlobalCoordsABC and
  updated ~ndcube.NDCubeABC, and ~ndcube.extra_coords.ExtraCoordsABC to
  reflect official NDCube 2 API definition in SEP.
  (#592)

Bug Fixes

• Fix bug #535 where NDCollection
  could not update when aligned_axes
  is None
  (#538)
• Fix a bug where aligned_axis_physical_types caused __str__ to error when aligned_axes was None.
  (#539)
• Fix a bug where data_unit was not being correctly passed through
  to the underlying plotting function when animating a cube.
  (#578)

Improved Documentation

• Add example to example gallery of how to create an NDCube from a
  FITS file. (#544)

v2.0.3 (2022-09-23)

Bug Fixes

• Dynamically copy docstring and function signature from NDCube.plotter.plot() to NDCube.plot().
  (#534)
• Fixed a bug where the plot_axes key
  was not respected when passing axes
  to plot for 2D cubes.
  (#551)
• Limit maximum reproject version to 0.9 due to API changes. ndcube
  2.1 will support the new reproject keyword arguments.
  (#564)

v2.0.2 (2022-05-10)

Bug Fixes

• Fix a bug in the NDCube._as_mpl_axes implementation, allowing
  cubes with compatible dimensions to be passed as the projection=
  keyword argument to certain matplotlib functions again.
  (#509)

Trivial/Internal Changes

• Remove use of deprecated distutils module.
  (#520)

2.0.1 (2021-11-19)

Bug Fixes

• Enable ~ndcube.NDCollection to accept
  aligned axes inputs in any integer type.
  (#495)
• Patch to convert quantity objects passed to crop_by_coords to the
  units given in the wcs.world_axis_units.
  (#497)
• Fix a bug which prevented the axes_units= kwarg from working when
  using the matplotlib animators.
  (#498)
• Add support for length-1 lookup table coords within extra coords.
  (#499)
• Bump the minimum version of astropy to 4.2 to correctly support
  capturing dropped world dimensions into global coords when slicing
  the WCS. (#500)

2.0.0 (2021-10-29)

Backwards Incompatible Changes

• Remove unused util functions and the ndcube WCS class. Refactor util
  functions for converting between between data and WCS indices to
  reflect the APE14 nomenclature that distinguishes between array,
  pixel and world axes.
  (#280)
• NDCubeSequence animation axes can no longer be set by extra coords.
  (#294)
• ImageAnimatorNDCubeSequence, ImageAnimatorCubeLikeNDCubeSequence,
  LineAnimatorNDCubeSequence and LineAnimatorCubeLikeNDCubeSequence
  have been removed and replaced by NDCubeSequenceAnimator.
  (#294)
• Change type of output of .NDCollection.aligned_world_axis_physical_types
  from tuple to list. This is to be consistent with output of astropy.wcs.WCS.world_axis_physical_types.
  (#302)
• Change output type when common axis item is a slice that covers only
  one subcube. Previously this would return an NDCube. Now an
  NDCubeSequence is always returned unless the common axis item is an
  integer. Also, refactor NDCubeSequence.index_as_cube so codebase
  is simpler. (#311)
• Replace NDCube.crop_by_coords and NDCube.crop_by_extra_coords
  with new method, NDCube.crop
  (#316)
• Remove NDCubeSequence plotting.
  (#322)
• Update .NDCube.array_axis_physical_types return
  physical types from extra coords as well as the WCS.
  (#338)
• Rename .ExtraCoords.add method from
  previous name "add_coordinate".
  (#394)
• The ~.NDcube object no longer
  inherits from astropy.nddata.NDArithmeticMixin as the
  methods were not coordinate aware.
  (#457)

Deprecations and Removals

• Remove NDCube.pixel_to_world and
  NDCube.world_to_pixel.
  (#300)
• Remove world_axis_physical_types methods from .NDCube and .NDCubeSequence.
  (#302)
• Remove NDCubeSequence.sequence_axis_extra_coords. This is
  replaced by NDCubeSequence.sequence_axis_coords.
  (#335)
• Remove ndcube.NDCubeSequence.common_axis_extra_coords.
  Will be replaced by ndcube.NDCubeSequence.common_axis_coords.
  (#344)
• Remove NDCollection.aligned_world_axis_physical_types. It will
  be replaced by ~ndcube.NDCollection.aligned_axis_physical_types.
  (#347)

Features

• Implement a new .ExtraCoords class
  which allows the specification of extra coordinates via lookup
  tables or WCS. This class exposes the extra coords as an APE 14 WCS
  object. (#271)

• Add new method, ~ndcube.NDCube.axis_world_coord_values,
  to return world coords for all pixels for all axes in WCS as
  quantity objects.
