Detailed Description

Select sources that have finite RA and Dec sky coordinate values

This object can be used as a `lsst.pex.config.Config` for configuring
the column names to check for "coord_ra" and "coord_dec" keys.

This will select against objects for which either the RA or Dec coordinate
entries are not numpy.isfinite().

◆ apply()

lsst.meas.algorithms.sourceSelector.RequireFiniteRaDec.apply	(		self,
			catalog )

Apply the sky coordinate requirements to a catalog

Returns whether the sources were selected.

Parameters
----------
catalog : `lsst.afw.table.SourceCatalog` or `pandas.DataFrame`
          or `astropy.table.Table`
    Catalog of sources to which the requirements will be applied.

Returns
-------
selected : `numpy.ndarray`
    Boolean array indicating for each source whether it is selected
    (True means selected).
