A trivial StarSelector 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 stars to use the set of stars used to determine the PSF.

Make a list of PSF candidates from a star catalog.
[in] | exposure | the exposure containing the sources |
[in] | starCat | catalog of stars (an lsst.afw.table.SourceCatalog), e.g. as returned by the run or selectStars method |

Select stars, make PSF candidates, and set a flag field True for stars in the input catalog.
[in] | exposure | the exposure containing the sources |
[in] | sourceCat | catalog of sources that may be stars (an lsst.afw.table.SourceCatalog) |
[in] | matches | astrometric matches; ignored by this star selector (an lsst.afw.table.ReferenceMatchVector), or None. Some star selectors will ignore this argument, others may require it. See the usesMatches class variable. |
[in] | isStarField | name of flag field to set True for stars, or None to not set a field; the field is left unchanged for non-stars |
