◆ run()

lsst.meas.algorithms.sourceSelector.BaseSourceSelectorTask.run	(	self,
		sourceCat,
		sourceSelectedField = None,
		matches = None,
		exposure = None )

inherited

Select sources and return them.

The input catalog must be contiguous in memory.

Parameters
----------
sourceCat : Various table formats
    Catalog of sources to select from. Can be
    `lsst.afw.table.SourceCatalog` or `pandas.DataFrame` or
    `astropy.table.Table`,
sourceSelectedField : `str` or None
    Name of flag field in sourceCat to set for selected sources.
    If set, will modify sourceCat in-place.
matches : `list` of `lsst.afw.table.ReferenceMatch` or None
    List of matches to use for source selection.
    If usesMatches is set in source selector this field is required.
    If not, it is ignored.
exposure : `lsst.afw.image.Exposure` or None
    The exposure the catalog was built from; used for debug display.

Returns
-------
struct : `lsst.pipe.base.Struct`
    The struct contains the following data:

    ``sourceCat``
        The catalog of sources that were selected.
        (may not be memory-contiguous)
        (`lsst.afw.table.SourceCatalog` or `pandas.DataFrame`
        or `astropy.table.Table`)
    ``selected``
        Boolean array of sources that were selected, same length as
        sourceCat.
        (`numpy.ndarray` of `bool`)

Raises
------
RuntimeError
    Raised if ``sourceCat`` is not contiguous.

Definition at line 72 of file sourceSelector.py.

◆ selectSources()

lsst.meas.algorithms.sourceSelector.NullSourceSelectorTask.selectSources	(		self,
			sourceCat,
		**	matches )

Return a selection of sources selected by some criteria.

Parameters
----------
sourceCat : Various table formats
    Catalog of sources to select from. Supports
    `lsst.afw.table.SourceCatalog` or `pandas.DataFrame`
    or `astropy.table.Table`
    This catalog must be contiguous in memory.
matches : `list` of `lsst.afw.table.ReferenceMatch` or None
    A list of lsst.afw.table.ReferenceMatch objects
exposure : `lsst.afw.image.Exposure` or None
    The exposure the catalog was built from; used for debug display.

Returns
-------
struct : `lsst.pipe.base.Struct`
    The struct contains the following data:

    ``selected``
        Boolean array of sources that were selected, same length as
        sourceCat.
        (`numpy.ndarray` of `bool`)
