Class Documentation

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

An intermediate base class for Psfs that use an image representation.

ImagePsf exists only to provide implementations of doComputeApertureFlux and doComputeShape for its derived classes. These implementations use the SincFlux and SdssShape algorithms defined in meas_algorithms, and hence could not be included with the Psf base class in afw.

Subclassed by lsst::meas::algorithms::CoaddPsf, lsst::meas::algorithms::KernelPsf, lsst::meas::algorithms::WarpedPsf, lsst::meas::extensions::psfex::PsfexPsf
