Methods Documentation
- determinePsf(exposure, psfCandidateList, metadata=None, flagKey=None)#
Determine a PSFEX PSF model for an exposure given a list of PSF candidates.
Parameters#
- exposure:
lsst.afw.image.Exposure Exposure containing the PSF candidates.
- psfCandidateList: iterable of
lsst.meas.algorithms.PsfCandidate Sequence of PSF candidates typically obtained by detecting sources and then running them through a star selector.
- metadata: metadata, optional
A home for interesting tidbits of information.
- flagKey:
lsst.afw.table.Key, optional Schema key used to mark sources actually used in PSF determination.
Returns#
- psf:
lsst.meas.extensions.psfex.PsfexPsf The determined PSF.
- exposure:
