Detailed Description

Base class for PSF determiners.

Register all PSF determiners with the psfDeterminerRegistry using: psfDeterminerRegistry.register(name, class)

Definition at line 54 of file psfDeterminer.py.

Constructor & Destructor Documentation

◆ init()

def lsst.meas.algorithms.psfDeterminer.BasePsfDeterminerTask.__init__	(	self,
		config,
		schema = `None`,
		kwds
	)

Construct a PSF Determiner

@param[in]       config   an instance of pexConfig.Config that configures this algorithm
@param[in,out]   schema   an instance of afw.table.Schema used for sources; passing a
                  schema allows the determiner to reserve a flag field to mark stars
                  used in PSF measurement, but some PSF determiners ignore this argument

Member Function Documentation

◆ determinePsf()

def lsst.meas.algorithms.psfDeterminer.BasePsfDeterminerTask.determinePsf	(	self,
		exposure,
		psfCandidateList,
		metadata = `None`
	)

Determine a PSF model

@param[in] exposure            exposure containing the psf candidates (lsst.afw.image.Exposure)
@param[in] psfCandidateList:   a sequence of PSF candidates (each an
                       lsst.meas.algorithms.PsfCandidate); typically obtained by
                       detecting sources and then running them through a star selector
@param[in,out] metadata        a place to save interesting items

@return
    - psf: the fit PSF; a subclass of lsst.afw.detection.Psf
    - cellSet: the spatial cell set used to determine the PSF (lsst.afw.math.SpatialCellSet)
