std::string
STL class.
lsst::meas::algorithms::DoubleGaussianPsf::getSigma2
double getSigma2() const
Return the radius of the outer Gaussian.
Definition: DoubleGaussianPsf.h:57
PTR
#define PTR(...)
Definition: base.h:41
sigma2

Definition: DoubleGaussianPsf.h:60
lsst::afw::table::io::PersistableFacade
A CRTP facade class for subclasses of Persistable.
Definition: Persistable.h:176
KernelPsf.h
lsst::meas::algorithms::DoubleGaussianPsf
Represent a Psf as a circularly symmetrical double Gaussian.
Definition: DoubleGaussianPsf.h:34
lsst::afw::detection::Psf
A polymorphic base class for representing an image's Point Spread Function.
