Format matched catalogs that may require coordinate conversions.
Parameters
----------
catalog_ref : `astropy.table.Table`
A reference catalog for comparison to `catalog_target`.
catalog_target : `astropy.table.Table`
A target catalog with measurements for comparison to `catalog_ref`.
select_ref : `numpy.ndarray`, (Nref,)
A boolean array of len `catalog_ref`, True for valid match candidates.
select_target : `numpy.ndarray`, (Ntarget,)
A boolean array of len `catalog_target`, True for valid match candidates.
radec_to_xy_func : `typing.Callable`
Function taking equal-length ra, dec arrays and returning an ndarray of
- ``x``: current parameter (`float`).
- ``extra_args``: additional arguments (`dict`).
kwargs
Additional keyword arguments to pass to radec_to_xy_func.
Returns
-------
compcat_ref, compcat_target : `ComparableCatalog`
Comparable catalogs corresponding to the input reference and target.
