Select sources that are useful for astrometry. Good astrometry sources have high signal/noise, are non-blended, and did not have certain "bad" flags set during source extraction. They need not be PSF sources, just have reliable centroids.

Return True for each source that is usable for matching and likely has a good centroid. The additional tests for a good centroid, beyond isUsable, are: - not interpolated in the center - not saturated - not near the edge

Return True for each source that is usable for matching, even if it may have a poor centroid. For a source to be usable it must: - have a valid centroid - not be deblended - have a valid flux (of the type specified in this object's constructor) - have adequate signal-to-noise

Return a selection of sources that are useful for astrometry. Parameters ---------- sourceCat : `lsst.afw.table.SourceCatalog` Catalog of sources to select from. This catalog must be contiguous in memory. 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`)
