ConfigClass = DirectMatchConfig | |
Simple, brute force matching of a source catalog to a reference catalog. Parameters ---------- butler : `lsst.daf.persistence.Butler` Data butler containing the relevant reference catalog data. refObjLoader : `lsst.meas.algorithms.LoadReferenceObjectsTask` or `None` For loading reference objects **kwargs : Other keyword arguments required for instantiating a Task (e.g., 'config')

def lsst.meas.astrom.directMatch.DirectMatchTask.calculateCircle | ( | self, | |
catalog | |||
) |
Calculate a circle enclosing the catalog Parameters ---------- catalog : `lsst.afw.table.SourceCatalog` Catalog to encircle Returns ------- result : `lsst.pipe.base.Struct` Result struct with components: - center : ICRS center coordinate (`lsst.afw.geom.SpherePoint`) - radius : Radius of the circle (`lsst.geom.Angle`)

) |
Load reference objects and match to them. Parameters ---------- catalog : `lsst.afw.table.SourceCatalog` Catalog to match. filterName : `str` Name of filter loading fluxes epoch : `astropy.time.Time` or `None` Epoch to which to correct proper motion and parallax, or `None` to not apply such corrections. Returns ------- result : `lsst.pipe.base.Struct` Result struct with components: - matches : Matched sources with associated reference (`lsst.afw.table.SourceMatchVector`) - matchMeta : Match metadata (`lsst.meas.astrom.MatchMetadata`)
