Class lsst::afw::detection::GaussianPsf

class GaussianPsf : public lsst::afw::table::io::PersistableFacade<GaussianPsf>, public lsst::afw::detection::Psf

A circularly symmetric Gaussian Psf class with no spatial variation, intended mostly for testing purposes.

This class is essentially an alternate implementation of meas::algorithms::SingleGaussianPsf; While SingleGaussianPsf inherits from ImagePsf and KernelPsf, and hence delegates to those various operations relating to the PSF model image (e.g. computeShape()), GaussianPsf computes these analytically.
