  To keep categorization correct, SDSS IV list no longer carries wavelengths less than 2000 Angstrom. [#3458]

• Fixed some broken flux conversions that were dropping the factor of solid angle. [#3457]

• subset_tools.get_regions uses app.get_subsets under the hood, which fixes retrieving composite subsets when sky linked as

• Add Roman WFI and CGI footprints to the Footprints plugin. [#3322, #3345]

• Catalog Search plugin now exposes a maximum sources limit for all catalogs and resolves an edge case
  when loading a catalog from a file that only contains one source. [#3337]

• Catalog Search plugin zoom_to_selected is now in the public API. The default
  zoom level changed from a fixed 50 pixels to a zoom window that is a fraction of
  the image size (default 2%) to address and issue with zooming when using a small
  image or WCS linked. [#3369]

Specviz

• Specviz parser will now split a spectrum with a 2D flux array into multiple spectra on load
  (useful for certain SDSS file types). [#3229]

API Changes

• Subset Tools plugin now exposes the subset, combination_mode, recenter_dataset,
  recenter, get_center, and set_center in the user API. [#3293, #3304, #3325]

  metadata_plugin.meta instead, which will return a Python dictionary instead of
  list of tuples. [#3292]

  regions or SpectralRegions, deprecate get_interactive_regions and get_spectral_regions. [#3340]

Bug Fixes

• Spectral extraction now correctly respects the loaded mask cube. [#3319, #3358]

Imviz

• Remove "From File.." option when running on an external server. [#3239]

• Button in the footprints plugin to change the link-type now redirects to the orientation plugin
  when the change fails due to the presence of subsets or markers. [#3276]

• Added flux/surface brightness translation and surface brightness
  unit conversion in Cubeviz and Specviz. [#2781, #2940, #3088, #3111, #3113, #3129,
  #3139, #3149, #3155, #3178, #3185, #3187, #3190, #3156, #3200, #3192, #3206, #3211, #3216, #3219]

  JWST [#3120, #3148, #3167, #3171, #3194]

• Unit columns are now visible by default in the results table in model fitting. [#3196]

Cubeviz

• Automatic spectral extraction now goes through the logic of the spectral extraction plugin for
  self-consistency. This results in several breaking changes to data-labels and get_data
  (the extracted spectra are now given dedicated data-labels instead of referring to them by
  the label of the flux cube) as well as to several plugins: model fitting, gaussian smooth,
  line analysis, and moment maps. [#2827]

• Background subtraction support within Spectral Extraction. [#2859]

• Aperture photometry plugin now listens to changes in display unit. [#3118]

Imviz

  future release. [#2894]

• Plugin Table components now support row selection. [#2856]

Cubeviz

• get_data no longer supports function or spatial_subset as arguments. To access
  an extracted 1D spectrum, use the Spectral Extraction plugin or the automatic extraction of
  spatial subsets, and refer to the data-label assigned to the resulting 1D spectrum. [#2827]

• Several plugins that take 1D spectra replace spatial_subset with referring to the 1D
  spectrum in dataset. This affects: model fitting, gaussian smooth, line analysis,
  and moment maps. [#2827]

• Removed deprecated cubeviz.select_slice() method. Use cubeviz.select_wavelength()
  instead. [#2878]

• In the Slice plugin, the following deprecated properties were removed: wavelength (use value),
  wavelength_unit (use value_unit), show_wavelength (use show_value),
  slice (use value). [#2878]

• Spectral Extraction: renamed collapse_to_spectrum(...) to extract(...). [#2859]

• Generic FITS parsing now goes through specutils loaders first, if possible.
  If a specutils loader is used, uncertainty is converted to standard deviation type. [#3119]

• Custom Spectrum1D writer format jdaviz-cube is removed. Use wcs1d-fits from
  specutils instead. [#2094]

• Aperture Photometry plugin now uses TRFLSQFitter to fit radial profile because LevMarLSQFitter
  is no longer recommended by Astropy. [#3202]

Imviz

• Deprecated Rotate Canvas plugin was removed; use Orientation plugin instead. [#2878]

• Aperture Photometry plugin now uses TRFLSQFitter to fit radial profile because LevMarLSQFitter
  is no longer recommended by Astropy. [#3202]

Specviz

• In the Line Analysis plugin, deprecated width was removed (use continuum_width). [#2878]

Bug Fixes

• Markers table can now export to CSV but its columns had to be changed to accomodate this fix:
  world and pixel (previously containing SkyCoord and pixel location tuples, respectively) are now
  each two separate columns for world_ra/world_dec and pixel_x/pixel_y, respectively. [#3089]

• Stretch histogram in zoom limits no longer attempts unnecessary updates when zoom limits are changed. [#3151]

• Aperture Photometry plugin no longer allows negative counts conversion factor. [#3154]

• Fixed multiple select handling for batch mode aperture photometry in Cubeviz. [#3163]

Cubeviz

• Moment map plugin now reflects selected flux / surface brightness unit for moment zero. [#2877]

• Update the scale factor used to convert a spectrum between surface brightness and flux
  to use wavelength-dependent aperture area instead of the cone slice scale factor. [#2860]

• Handle display units when doing flux / surface brightness conversions. [#2910]

• Flux units are now correct for collapsed spectra when using the sum function
  when units are in per steradian. [#2873]

• Mouse over coordinates now responds to the selected surface brightness unit. [#2931]

• Fixed MaNGA cube loading. Uncertainty type is also handled properly now. [#3119]

• Fixed spectral axis value display in Markers plugin. Previously, it failed to display
  very small values, resulting in zeroes. [#3119]

• No longer incorrectly swap RA and Dec axes when loading Spectrum1D objects. [#3133]

• Fixed fitting a model to the entire cube when NaNs are present. [#3191]

Specviz2d

• Fixed Subset unit when it is created in 2D spectrum viewer. [#3201]

• Fix matched mouseover marker for 1d spectrum viewer when mouse is over 2d spectrum viewer. [#3203]

Other Changes and Additions

• Bump required specutils version to 1.18. Moment 0 calculation is now in units
  of flux*dx (rather than flux) [#3184]

v3.10.3

3.10.3 (2024-07-22)

Bug Fixes

• Fixes exporting the stretch histogram from Plot Options before the Plot Options plugin is ever opened. [#2934]

• Previous zoom tool is optimized to only issue one zoom update to the viewer. [#2949]

• Fixes overwrite behavior for plugin plots, and properly closes overwrite warning overlay after confirmation. [#3094]

• Disable all non-image exporting when the server is not running locally, to avoid confusion with the file being saved on the server. [#3096]

Cubeviz

• Fixed a bug with filename handling for movie exports. [#2942]

Imviz

• Fix multiple footprints bug that prevented footprint updates on changes to the
  viewer orientation. [#2918]
