A star selector that looks for a cluster of small objects in a size-magnitude plot.
A star selector that looks for a cluster of small objects in a size-magnitude plot.
Like all star selectors, the main method is run
.

ObjectSizeStarSelectorTask has a debug dictionary with the following keys:
For example, put something like:
into your debug.py
file and run your task with the --debug
flag.

Select stars and set a flag field True for stars in the input catalog. Parameters ---------- exposure : `lsst.afw.image.Exposure` the exposure containing the sources sourceCat : `lsst.afw.table.SourceCatalog` catalog of sources that may be stars matches : `lsst.afw.table.ReferenceMatchVector` or None astrometric matches; ignored by this star selector. Some star selectors will ignore this argument, others may require it. See the usesMatches class variable. isStarField : `str` name of flag field to set True for stars, or None to not set a field; the field is left unchanged for non-stars Returns ------- struct : `lsst.pipe.base.Struct` Result struct containing: - starCat catalog of stars that were selected as stars and successfuly made into PSF candidates (a subset of sourceCat whose records are shallow copies)

Return a list of PSF candidates that represent likely stars.
A list of PSF candidates may be used by a PSF fitter to construct a PSF.
