INFO: Subset API audit 2/4 (get, export, write)

subset_tools.get_regions(): We want this to be the canonical API.

jdaviz/jdaviz/configs/default/plugins/subset_tools/subset_tools.py

Lines 182 to 183 in 4ffc3a0

	def get_regions(self, region_type=None, list_of_subset_labels=None,
	use_display_units=False):

jdaviz/jdaviz/configs/default/plugins/subset_tools/subset_tools.py

Lines 207 to 212 in 4ffc3a0

	Returns
	-------
	regions : dict
	A dictionary mapping subset labels to their respective ``regions``
	objects (for spatial regions) or ``SpectralRegions`` objects
	(for spectral regions).

jdaviz.app.get_subsets(): We want to be able to replace this with subset_tools.get_regions() or have subset_tools.get_regions() call this instead, but somehow it was not possible, why? Note that this method is way more complicated than the one in subset_tools and calls another recursive method and also is more powerful. Need to think how to consolidate the two.

jdaviz/jdaviz/app.py

Lines 921 to 924 in 4ffc3a0

	def get_subsets(self, subset_name=None, spectral_only=False,
	spatial_only=False, object_only=False,
	simplify_spectral=True, use_display_units=False,
	include_sky_region=False):

jdaviz/jdaviz/app.py

Lines 952 to 957 in 4ffc3a0

	Returns
	-------
	data : dict
	Returns a nested dictionary with, for each subset, 'name', 'glue_state',
	'region', 'sky_region' (set to None if not applicable), and 'subset_state'.
	If subset is composite, each constituant subset will be included individually.

jdaviz.app.get_sub_regions(): Only used internally in jdaviz.app.get_subsets(). Keep an eye out in case it is no longer necessary if we remove jdaviz.app.get_subsets().
