v4.1.0

4.1 (2024-12-23)

New Features

• New design for viewer legend and future data-menu. [#3220, #3254, #3263, #3264, #3271, #3272, #3274, #3289, #3310, #3370]

• Improve performance while importing multiple regions. [#3321]

• API method to toggle API hints. [#3336]

• Changing flux/SB display units no longer resets viewer zoom levels. [#3335]

Cubeviz

• Add Sonify Data plugin which uses the Strauss package to turn a data cube into sound. [#3269]

Imviz

• Orientation plugin API now exposes create_north_up_east_left and create_north_up_east_right methods. [#3308]

• 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

• Removed API access to plugins that have passed the deprecation period: Links Control, Canvas Rotation, Export Plot. [#3270]

• 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: metadata_plugin.metadata API has been deprecated; use
  metadata_plugin.meta instead, which will return a Python dictionary instead of
  list of tuples. [#3292]

• Add get_regions method to subset plugin to retrieve spatial/spectral subsets as
  regions or SpectralRegions, deprecate get_interactive_regions and get_spectral_regions. [#3340]

Bug Fixes

• Fixed broken flux unit conversions in all plugins that respond to changes in flux unit changes. These cases
  occured when certain flux-to flux-conversions occured, as well as certain conversions between flux and surface
  brightness. This PR also fixed an issue with unit string formatting in the aperture photometry plugin. [#3228]

• Fixed broken histogram pan/zoom in Plot Options plugin. [#3361]

• Fixed bug with Plot Options select_all when data is float32. [#3366]

• Fixed an issue with back-to-back calls of set_limits and get_limits. [#3371]

• Added a short description of each plugin in the side menu, visible before the plugin is opened. Removes redundant descriptions above link
  out to documentation when plugin is opened. Enable search on plugin description in addition to title. [#3268]

• Improved performance of app.get_subsets for the single-subset case. [#3363]

v4.0.1

  in the spectrum-viewer when spectral y units are converted. [#3242]

• Added nbclassic dependency to fix solara-based popouts. [#3282]

• Fixed viewer widgets displaying improperly if initialized out of view in Jupyter Lab. [#3299]

• Fixed width of sliders in plugins to use full-width of plugin. [#3303]

• Raise an error when attempting to open in a popout or sidecar when not supported (i.e. within VSCode). [#3309]

Cubeviz

• Fixed "spectrum at spaxel" tool so it no longer resets spectral axis zoom. [#3249]

• Fixed initializing a Gaussian1D model component when Cube Fit is toggled on. [#3295]

• 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]

• Updates UI language in the orientation plugin to better match API. [#3276]

• Update Roman L2 example files in example notebook. [#3346]

4.0 (2024-10-17)

New Features

• Added ability to load remote data from a URI or URL. [#2875, #2923]

• 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]

• Plugins can now expose in-UI API hints. [#3137, #3159]

• The standalone version of jdaviz now uses solara instead of voila, resulting in faster load times. [#2909]

• New configuration for ramp/Level 1 and rate image/Level 2 data products from Roman WFI and
  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

  Monochromatic will continue to work with a deprecation warning, but may be removed in a
  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]
