Represent a PSF as a circularly symmetrical Gaussian.

Public Functions

SingleGaussianPsf(int width, int height, double sigma)¶

Constructor for a SingleGaussianPsf.

Additional arguments are historical and ignored, and maybe be removed in the future.

Parameters

[in] width: Number of columns in realizations of the PSF at a point.
[in] height: Number of rows in realizations of the PSF at a point.
[in] sigma: Radius of the Gaussian.

PTR(afw::detection::Psf) const¶: Polymorphic deep copy; should usually unnecessary because Psfs are immutable.

PTR(afw::detection::Psf)¶: Return a clone with specified kernel dimensions.

double getSigma() const¶: Return the radius of the Gaussian.

bool isPersistable() const¶: Whether the Psf is persistable; always true.
