afw::table::Key< double > sigma
Definition: GaussianPsf.cc:49
Basic LSST definitions.
An object passed to Persistable::write to allow it to persist itself.
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 circularly symmetrical Gaussian.
bool isPersistable() const noexcept override
Whether the Psf is persistable; always true.
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.
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.
double getSigma() const
Return the radius of the Gaussian.
SingleGaussianPsf(int width, int height, double sigma)
Constructor for a SingleGaussianPsf.
A base class for image defects.
