FgcmOutputProductsTask

class lsst.fgcmcal.FgcmOutputProductsTask(**kwargs)

Bases: PipelineTask

Output products from FGCM global calibration.

Methods Summary

generateTractOutputProducts(handleDict, ...)	Generate the output products for a given tract, as specified in the config.
run(handleDict, physicalFilterMap)	Run the output products task.
runQuantum(butlerQC, inputRefs, outputRefs)	Do butler IO and transform to provide in memory objects for tasks run method.

Methods Documentation

generateTractOutputProducts(handleDict, tract, visitCat, zptCat, atmCat, stdCat, fgcmBuildStarsConfig)

Generate the output products for a given tract, as specified in the config.

This method is here to have an alternate entry-point for FgcmCalibrateTract.

Parameters

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.
