Basic LSST definitions.
#define PTR(...)
Definition: base.h:41
A Psf defined by a Kernel.
Definition: KernelPsf.h:36
An object passed to Persistable::write to allow it to persist itself.
bool isPersistable() const noexcept override
Whether the Psf is persistable; always true.
STL class.
double getSigma() const
Return the radius of the Gaussian.
Represent a PSF as a circularly symmetrical Gaussian.
boost::shared_ptr< afw::detection::Psf > clone() const override
Polymorphic deep copy; should usually unnecessary because Psfs are immutable.
A base class for image defects.
SingleGaussianPsf(int width, int height, double sigma)
Constructor for a SingleGaussianPsf.
afw::table::Key< double > sigma
Definition: GaussianPsf.cc:50
A polymorphic base class for representing an image&#39;s Point Spread Function.
Definition: Psf.h:76
A CRTP facade class for subclasses of Persistable.
Definition: Persistable.h:176
boost::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.
