runSelection#

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

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:

  • refObjLoader (meas.algorithms.ReferenceObjectLoader) – Reference object loader to use in getting reference objects.

  • detector (lsst.afw.cameraGeom.Detector) – Detector object from the camera.

  • wcs (lsst.afw.geom.SkyWcs) – Wcs object defining the pixel to sky (and inverse) transform for the supplied bbox.

  • filterName (str) – Name of camera filter.

  • donutSelectorTask (lsst.ts.wep.task.DonutSourceSelectorTask or None) – Task to run the donut source selection algorithm. If set to None, the catalog will be the exact same as the reference catalogs without any donut selection algorithm applied.

  • edgeMargin (int) – The width of the margin by which we decrease bbox to avoid edge source selection.

Return type:

tuple[QTable, list, list]

Returns:

  • referenceCatalog (lsst.afw.table.SimpleCatalog) – Catalog containing reference objects inside the specified bounding box and with properties within the bounds set by the referenceSelector.

  • list – X pixel location of centroids of blended donuts.

  • list – Y pixel location of centroids of blended donuts.
