- Update to 1.4.0
New Features
* photutils.aperture
* Added a copy method to Aperture objects. [#1304]
* Added the ability to compare Aperture objects for equality.
[#1304]
* The theta keyword for EllipticalAperture, EllipticalAnnulus,
RectangularAperture, and RectangularEllipse can now be an
Astropy Angle or Quantity in angular units. [#1308]
* Added an ApertureStats class for computing statistics of
unmasked pixels within an aperture. [#1309, #1314, #1315,
#1318]
* Added a dtype keyword to the ApertureMask to_image method.
[#1320]
* photutils.background
* Added an alpha keyword to the Background2D.plot_meshes
method. [#1286]
* Added a clip keyword to the BkgZoomInterpolator class.
[#1324]
* photutils.segmentation
* Added SegmentationImage cmap attribute containing a default
colormap. [#1319]
* Improved the performance of SegmentationImage and
SourceCatalog, especially for large data arrays. [#1320]
* Added a convolved_data keyword to SourceCatalog. This is
recommended instead of using the kernel keyword. [#1321]
Bug Fixes
* photutils.aperture
* Fixed a bug in aperture_photometry where an error was not
raised if the data and error arrays have different units.
[#1285].
* photutils.background
* Fixed a bug in Background2D where using the pad edge method
would result in incorrect image padding if only one of the
axes needed padding. [#1292]
* photutils.centroid
* Fixed a bug in centroid_sources where setting error, xpeak,
or ypeak to None would result in an error. [#1297]
* Fixed a bug in centroid_quadratic where inputting a mask
would alter the input data array. [#1317]
* photutils.segmentation
* Fixed a bug in SourceCatalog where a UFuncTypeError would be
raised if the input data had an integer dtype [#1312].
API Changes
* photutils.aperture
* A ValueError is now raised if non-positive sizes are input to
sky-based apertures. [#1295]
* The BoundingBox.plot() method now returns a
matplotlib.patches.Patch object. [#1305]
* Inputting PixelAperture positions as an Astropy Quantity in
pixel units is deprecated. [#1310]
* Inputting SkyAperture shape parameters as an Astropy Quantity
in pixel units is deprecated. [#1310]
* photutils.background
* Removed the deprecated background_mesh_ma and
background_rms_mesh_ma Background2D properties. [#1280]
* By default, BkgZoomInterpolator uses clip=True to prevent the
interpolation from producing values outside the given input
range. If backwards-compatiblity is needed with older
Photutils versions, set clip=False. [#1324]
* photutils.centroid
* Removed the deprecated centroid_epsf and gaussian1d_moments
functions. [#1280]
* Importing tools from the centroids subpackage now requires
including the subpackage name. [#1280]
* photutils.morphology
* Importing tools from the morphology subpackage now requires
including the subpackage name. [#1280]
* photutils.segmentation
* Removed the deprecated source_properties function and the
SourceProperties and LegacySourceCatalog classes. [#1280]
* Removed the deprecated the filter_kernel keyword in the
detect_sources, deblend_sources, and make_source_mask
functions. [#1280]
* A TypeError is raised if the input array to SegmentationImage
does not have integer type. [#1319]
* A SegmentationImage may contain an array of all zeros.
[#1319]
* Deprecated the mask_value keyword in detect_threshold. Use
the mask keyword instead. [#1322]
* Deprecated the filter_fwhm and filter_size keywords in
make_source_mask. Use the kernel keyword instead. [#1322]
