Function lsst::ip::diffim::makeAlardLuptonBasisList

Function Documentation

lsst::afw::math::KernelList lsst::ip::diffim::makeAlardLuptonBasisList(int halfWidth, int nGauss, std::vector<double> const &sigGauss, std::vector<int> const &degGauss)

Build a set of Alard/Lupton basis kernels.

Note

Should consider implementing as SeparableKernels for additional speed, but this will make the normalization a bit more complicated

Parameters

  • halfWidth: size is 2*N + 1

  • nGauss: number of gaussians

  • sigGauss: Widths of the Gaussian Kernels

  • degGauss: Local spatial variation of bases
