lsst.ts.wep.task.runSelection(refObjLoader, detector, wcs, filterName, donutSelectorTask)

Match the detector area to the reference catalog and then run the LSST DM reference selection task. For configuration parameters on the reference selector see lsst.meas.algorithms.ReferenceSourceSelectorConfig.

Parameters:

refObjLoadermeas.algorithms.ReferenceObjectLoader

Reference object loader to use in getting reference objects.

detectorlsst.afw.cameraGeom.Detector

Detector object from the camera.

wcslsst.afw.geom.SkyWcs

Wcs object defining the pixel to sky (and inverse) transform for the supplied bbox.

filterNamestr
