◆ determinePsf()

lsst.meas.algorithms.pcaPsfDeterminer.PcaPsfDeterminerTask.determinePsf	(	self,
		exposure,
		psfCandidateList,
		metadata = None,
		flagKey = None )

Determine a PCA PSF model for an exposure given a list of PSF candidates.

Parameters
----------
exposure : `lsst.afw.image.Exposure`
   Exposure containing the psf candidates.
psfCandidateList : `list` of `lsst.meas.algorithms.PsfCandidate`
   A sequence of PSF candidates typically obtained by detecting sources
   and then running them through a star selector.
metadata : `lsst.daf.base import PropertyList` or `None`, optional
   A home for interesting tidbits of information.
flagKey : `str`, optional
   Schema key used to mark sources actually used in PSF determination.

Returns
-------
psf : `lsst.meas.algorithms.PcaPsf`
   The measured PSF.
psfCellSet : `lsst.afw.math.SpatialCellSet`
   The PSF candidates.

Reimplemented from lsst.meas.algorithms.psfDeterminer.BasePsfDeterminerTask.

◆ downsampleCandidates()

lsst.meas.algorithms.psfDeterminer.BasePsfDeterminerTask.downsampleCandidates	(		self,
			inputCandidateList )

inherited

Down-sample candidates from the input candidate list.

Parameters
----------
inputCandidateList : `list` [`lsst.meas.algorithms.PsfCandidate`]
    Input candidate list.

Returns
-------
outputCandidateList : `list` [`lsst.meas.algorithms.PsfCandidate`]
    Down-selected candidate list.
