void lsst::ip::diffim::KernelCandidate< PixelT >::build | ( | afw::math::KernelList const & | basisList | ) |
Core functionality of KernelCandidate, to build and fill a KernelSolution.
o _isInitialized = false. This is a constructed but not initialized KernelCandidate. When build() is called, M and B are derived from the MaskedImages and the basisList. KernelCandidate owns the knowledge of how to fill this KernelSolution; the solution knows how to solve itself and how to turn that into an output kernel. This solution ends up being _kernelSolution0.
o _isInitialized = true. This is for when build() is re-called using a different basis list, e.g. one based on Pca. We need to use M and B for the spatial modeling, but do not want to override the original KernelSolution. This solution ends up as _kernelSolutionCurrent. Build KernelSolution matrices for M x = B with regularization matrix H
