RequireFiniteRaDec#

class lsst.meas.algorithms.RequireFiniteRaDec(*args, **kw)#

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().

Attributes Summary

`decColName`	Name of column for Dec coordinate (`str`, default `'coord_dec'`)
`raColName`	Name of column for RA coordinate (`str`, default `'coord_ra'`)

Methods Summary

apply(catalog)

Apply the sky coordinate requirements to a catalog

Attributes Documentation

decColName#: Name of column for Dec coordinate (str, default 'coord_dec')

Methods Documentation

apply(catalog)#

Apply the sky coordinate requirements to a catalog

Returns whether the sources were selected.

Parameters#

cataloglsst.afw.table.SourceCatalog or pandas.DataFrame: or astropy.table.Table

Catalog of sources to which the requirements will be applied.

selectednumpy.ndarray: Boolean array indicating for each source whether it is selected (True means selected).
