afw::table::PointKey< double > averagePosition
Definition: CoaddPsf.cc:353
A Psf defined by a Kernel.
Definition: KernelPsf.h:36
Represent a PSF as a linear combination of PCA (== Karhunen-Loeve) basis functions.
Definition: PcaPsf.h:37
PcaPsf(std::shared_ptr< afw::math::LinearCombinationKernel > kernel, geom::Point2D const &averagePosition=geom::Point2D())
Constructor for a PcaPsf.
std::shared_ptr< afw::detection::Psf > resized(int width, int height) const override
Return a clone with specified kernel dimensions.
std::shared_ptr< afw::math::LinearCombinationKernel const > getKernel() const
PcaPsf always has a LinearCombinationKernel, so we can override getKernel to make it more useful.
std::shared_ptr< afw::detection::Psf > clone() const override
Polymorphic deep copy; should usually be unnecessary as Psfs are immutable.x.
