Detailed Description

Select sources using a magnitude limit

Note that this assumes that a zero-point has already been applied and
the fluxes are in AB fluxes in Jansky. It is therefore principally
intended for reference catalogs rather than catalogs extracted from
science images.

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.

◆ apply()

def lsst.meas.algorithms.sourceSelector.MagnitudeLimit.apply (   self,
  catalog 
)
Apply the magnitude limits to a 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).

Reimplemented from lsst.meas.algorithms.sourceSelector.BaseLimit.
