table::Key< double > sigma2

io::OutputArchiveHandle OutputArchiveHandle
Represent a Psf as a circularly symmetrical double Gaussian.
bool isPersistable() const noexcept override
Whether this Psf is persistable (always true for DoubleGaussianPsf).
std::string getPersistenceName() const override
void write(OutputArchiveHandle &handle) const override
double getSigma1() const
Return the radius of the inner Gaussian.
DoubleGaussianPsf(int width, int height, double sigma1, double sigma2=0.0, double b=0.0)
Constructor for a DoubleGaussianPsf.
double getSigma2() const
Return the radius of the outer Gaussian.
std::shared_ptr< afw::detection::Psf > clone() const override
Polymorphic deep copy. Usually unnecessary, as Psfs are immutable.
double getB() const
Return the ratio of Gaussian peak amplitudes: outer/inner.
std::shared_ptr< afw::detection::Psf > resized(int width, int height) const override
Return a clone with specified kernel dimensions.
A Psf defined by a Kernel.
