pipeBase.Struct lsst.pipe.tasks.match_tract_catalog.MatchTractCatalogTask.run ( self,

Match sources in a reference tract catalog with a target catalog.

Parameters
----------
catalog_ref : `pandas.DataFrame`
    A reference catalog to match objects/sources from.
catalog_target : `pandas.DataFrame`
    A target catalog to match reference objects/sources to.
wcs : `lsst.afw.image.SkyWcs`
    A coordinate system to convert catalog positions to sky coordinates,
    if necessary.

Returns
-------
retStruct : `lsst.pipe.base.Struct`
    A struct with output_ref and output_target attribute containing the
    output matched catalogs.
