Detailed Description

Select sources using a color limit

This object can be used as a `lsst.pex.config.Config` for configuring
the limit, and then the `apply` method can be used to identify sources
in the catalog that match the configured limit.

We refer to 'primary' and 'secondary' flux measurements; these are the
two components of the color, which is:

    instFluxToMag(cat[primary]) - instFluxToMag(cat[secondary])

◆ apply()

def lsst.meas.algorithms.sourceSelector.ColorLimit.apply	(	self,
		catalog
	)

Parameters
----------
catalog : `lsst.afw.table.SourceCatalog`
    Catalog of sources to which the limit will be applied.

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