afw::table::Key< double > sigma
Basic LSST definitions.
An object passed to Persistable::write to allow it to persist itself.
A CRTP facade class for subclasses of Persistable.
A Psf defined by a Kernel.
Definition KernelPsf.h:36
Represent a PSF as a circularly symmetrical Gaussian.
bool isPersistable() const noexcept override
Whether the Psf is persistable; always true.
std::shared_ptr< afw::detection::Psf > clone() const override
Polymorphic deep copy; should usually unnecessary because Psfs are immutable.
std::shared_ptr< afw::detection::Psf > resized(int width, int height) const override
Return a clone with specified kernel dimensions.
void write(OutputArchiveHandle &handle) const override
Write the object to one or more catalogs.
std::string getPersistenceName() const override
Return the unique name used to persist this object and look up its factory.
double getSigma() const
Return the radius of the Gaussian.
SingleGaussianPsf(int width, int height, double sigma)
Constructor for a SingleGaussianPsf.
