MeasureExtendedPsfTask#

class lsst.pipe.tasks.extended_psf.MeasureExtendedPsfTask(initInputs=None, *args, **kwargs)#

Bases: Task

Build and save extended PSF model.

The model is built by stacking bright star stamps, extracted and preprocessed by lsst.pipe.tasks.processBrightStars.ProcessBrightStarsTask.

If a mapping from detector IDs to focal plane regions is provided, a different extended PSF model will be built for each focal plane region. If not, a single constant extended PSF model is built with all available data.

Methods Summary

runQuantum(butlerQC, inputRefs, outputRefs)
