Class Documentation

class PcaPsf : public lsst::afw::table::io::PersistableFacade<PcaPsf>, public lsst::meas::algorithms::KernelPsf

Represent a PSF as a linear combination of PCA (== Karhunen-Loeve) basis functions.

Public Functions

lsst::meas::algorithms::PcaPsf::PcaPsf(PTR ( afw::math::LinearCombinationKernel ) kernel, geom::Point2D const & averagePosition = geom::Point2D())

Constructor for a PcaPsf.

Parameters

  • [in] kernel: Kernel that defines the Psf.

  • [in] averagePosition: Average position of stars used to construct the Psf.

PTR(afw::detection::Psf) const

Polymorphic deep copy; should usually be unnecessary as Psfs are immutable.x.

PTR(afw::detection::Psf)

Return a clone with specified kernel dimensions.

PTR(afw::math::LinearCombinationKernel const) const

PcaPsf always has a LinearCombinationKernel, so we can override getKernel to make it more useful.
