Methods Documentation

fgcmMakeAllStarObservations(groupedHandles, visitCat, sourceSchema, camera, calibFluxApertureRadius=None)

Compile all good star observations from visits in visitCat.

Parameters

groupedHandlesdict [list [lsst.daf.butler.DeferredDatasetHandle]]

Dataset handles, grouped by visit.

visitCatafw.table.BaseCatalog

Catalog with visit data for FGCM

sourceSchemalsst.afw.table.Schema

Schema for the input src catalogs.

camera : lsst.afw.cameraGeom.Camera calibFluxApertureRadius : float, optional

Aperture radius for calibration flux.

inStarObsCatafw.table.BaseCatalog

Input observation catalog. If this is incomplete, observations will be appended from when it was cut off.

Returns

fgcmStarObservationsafw.table.BaseCatalog

Full catalog of good observations.

Raises

RuntimeError: Raised if doSubtractLocalBackground is True and

calibFluxApertureRadius is not set.

runQuantum(butlerQC, inputRefs, outputRefs)

Do butler IO and transform to provide in memory objects for tasks run method.

Parameters

butlerQCQuantumContext

A butler which is specialized to operate in the context of a lsst.daf.butler.Quantum.

inputRefsInputQuantizedConnection

Datastructure whose attribute names are the names that identify connections defined in corresponding PipelineTaskConnections class. The values of these attributes are the lsst.daf.butler.DatasetRef objects associated with the defined input/prerequisite connections.

outputRefsOutputQuantizedConnection

Datastructure whose attribute names are the names that identify connections defined in corresponding PipelineTaskConnections class. The values of these attributes are the lsst.daf.butler.DatasetRef objects associated with the defined output connections.
