Class lsst::afw::math::SeparableKernel

class SeparableKernel : public lsst::afw::table::io::PersistableFacade<SeparableKernel>, public lsst::afw::math::Kernel

A kernel described by a pair of functions: func(x, y) = colFunc(x) * rowFunc(y)

The function’s x, y arguments are as follows:

• -getCtr() for the lower left corner pixel

• 0, 0 for the center pixel

• (getDimensions() - 1) - getCtr() for the upper right pixel

Note: each pixel is set to the value of the kernel function at the center of the pixel (rather than averaging the function over the area of the pixel).
