Parameters

num_available_starsint

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.
