Determine a PSF model.
Parameters
----------
exposure : `lsst.afw.Exposure`
Exposure containing the psf candidates.
psdCandidateList : `list` [`lsst.meas.algorithms.PsfCandidate`]
A sequence of PSF candidates; typically obtained by
detecting sources and then running them through a star
selector.
metadata : `str`
A place to save interesting items.
Returns
-------
psf : `lsst.afw.detection.Psf`
The fit PSF.
cellSet : `lsst.afw.math.SpatialCellSet`
The spatial cell set used to determine the PSF

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.
