#define PTR(...)
Definition: base.h:41
A polymorphic base class for representing an image's Point Spread Function.
Definition: Psf.h:76
A kernel that is a linear combination of fixed basis kernels.
Definition: Kernel.h:705
A CRTP facade class for subclasses of Persistable.
Definition: Persistable.h:176
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
boost::shared_ptr< afw::detection::Psf > resized(int width, int height) const override
Return a clone with specified kernel dimensions.
boost::shared_ptr< afw::math::LinearCombinationKernel const > getKernel() const
PcaPsf always has a LinearCombinationKernel, so we can override getKernel to make it more useful.
boost::shared_ptr< afw::detection::Psf > clone() const override
Polymorphic deep copy; should usually be unnecessary as Psfs are immutable.x.
PcaPsf(boost::shared_ptr< afw::math::LinearCombinationKernel > kernel, geom::Point2D const &averagePosition=geom::Point2D())
Constructor for a PcaPsf.
A base class for image defects.
afw::table::PointKey< double > averagePosition
