void save_construct_data(Archive &ar, lsst::meas::algorithms::DoubleGaussianPsf const *p, unsigned int const )
friend class boost::serialization::access
Definition: PcaPsf.h:59
Represent a PSF as a linear combination of PCA (== Karhunen-Loeve) basis functions.
Definition: PcaPsf.h:34
boost::shared_ptr< afw::math::LinearCombinationKernel const > getKernel() const
PcaPsf always has a LinearCombinationKernel, so we can override getKernel to make it more useful...
A kernel that is a linear combination of fixed basis kernels.
Definition: Kernel.h:814
virtual afw::geom::Point2D getAveragePosition() const
Return average position of stars; used as default position.

virtual boost::shared_ptr< afw::detection::Psf > clone() const
Polymorphic deep copy; should usually be unnecessary as Psfs are immutable.x.
A polymorphic base class for representing an image&#39;s Point Spread Function.
Definition: Psf.h:68
PcaPsf(boost::shared_ptr< afw::math::LinearCombinationKernel > kernel, afw::geom::Point2D const &averagePosition=afw::geom::Point2D())
Constructor for a PcaPsf.
A CRTP facade class for subclasses of Persistable.
