PsfexTooFewGoodStarsError

exception lsst.meas.extensions.psfex.psfexPsfDeterminer.PsfexTooFewGoodStarsError(num_available_stars, num_good_stars, poly_ndim_initial, poly_ndim_final)

Raised if too few good stars are available for PSF determination.

Parameters:

num_available_starsint

Number of available stars for PSF determination.

num_good_starsint

Number of good stars used for PSF determination.

poly_ndim_initialint

Initial number of dependency parameters (dimensions) used in polynomial fitting.

poly_ndim_finalint

Final number of dependency parameters (dimensions) set in the PSFEx model after initializing the PSF structure.
