      Description

      The coadd level catalogs include a flag:

      "detect_isPrimary", type="Flag",
       doc="true if source has no children and is in the inner region of a coadd patch "
                "and is in the inner region of a coadd tract "
                "and is not \"detected\" in a pseudo-filter (see config.pseudoFilterList)",
      

      that is very useful for culling catalogs of duplicate (patch/tract overlap), non-deblended parent sources (deblend_nChild>0, and sky objects. No equivalent flag currently exists at the visit /single frame measurement level, so this ticket is to add such a flag. Currently, the only two conditions to be added to flag undesirable sources are:
      deblend_nChild == 0
      sky_source is False
