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])

lsst.meas.algorithms.sourceSelector.ColorLimit.apply | ( | self, | |
catalog ) |
Apply the color limit to a catalog Parameters ---------- catalog : Various table formats Catalog of sources to which the limit will be applied. Supports `lsst.afw.table.SourceCatalog` or `pandas.DataFrame` or `astropy.table.Table` Returns ------- selected : `numpy.ndarray` Boolean array indicating for each source whether it is selected (True means selected).
Reimplemented from lsst.meas.algorithms.sourceSelector.BaseLimit.
