io::OutputArchiveHandle OutputArchiveHandle
An intermediate base class for Psfs that use an image representation.
Definition: ImagePsf.h:40
A Psf class that maps an arbitrary Psf through a coordinate transformation.
Definition: WarpedPsf.h:52
void write(OutputArchiveHandle &handle) const override
Definition: WarpedPsf.cc:289
std::shared_ptr< afw::detection::Psf > resized(int width, int height) const override
Return a clone with specified kernel dimensions.
Definition: WarpedPsf.cc:195
geom::Point2D getAveragePosition() const override
Return the average of the positions of the stars that went into this Psf.
Definition: WarpedPsf.cc:187

Definition: WarpedPsf.h:94
std::shared_ptr< afw::detection::Psf const > _undistortedPsf
Definition: WarpedPsf.h:93
WarpedPsf(std::shared_ptr< afw::detection::Psf const > undistortedPsf, std::shared_ptr< afw::geom::TransformPoint2ToPoint2 const > distortion, std::shared_ptr< afw::math::WarpingControl const > control)
Construct WarpedPsf from unwarped psf and distortion.
Definition: WarpedPsf.cc:153
std::string getPersistenceName() const override
Definition: WarpedPsf.cc:286
std::shared_ptr< afw::detection::Psf > clone() const override
Polymorphic deep copy. Usually unnecessary, as Psfs are immutable.
