Detailed Description
A trivial SourceSelector that simply uses an existing flag field to filter
a SourceCatalog.
This is most frequently used in steps that occur after the a PSF model has
been built, to allow other procedures that need Sources to use the set of
Sources used to determine the PSF.
Attributes
----------
usesMatches : `bool`
A boolean variable specify if the inherited source selector uses
matches.

◆ selectSources()
| lsst.meas.algorithms.flaggedSourceSelector.FlaggedSourceSelectorTask.selectSources | ( | self, | |
| sourceCat, | |||
| matches = None, | |||
| exposure = None ) |
Return a bool array representing which sources to select from
sourceCat.
The input catalog must be contiguous in memory.
Parameters
----------
sourceCat : `lsst.afw.table.SourceCatalog`
Catalog of sources to select from.
matches : `list` of `lsst.afw.table.ReferenceMatch` or None
Ignored in this SourceSelector.
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`)
Reimplemented from lsst.meas.algorithms.sourceSelector.BaseSourceSelectorTask.
