makeKernelBasisList

lsst.ip.diffim.makeKernelBasisList(config, targetFwhmPix=None, referenceFwhmPix=None, basisDegGauss=None, metadata=None)

Generate the delta function or Alard-Lupton kernel bases depending on the Config. Wrapper to call either lsst.ip.diffim.makeDeltaFunctionBasisList or lsst.ip.diffim.generateAlardLuptonBasisList.

Parameters:

config : lsst.ip.diffim.PsfMatchConfigAL

Configuration object.

targetFwhmPix : float, optional

Passed on to lsst.ip.diffim.generateAlardLuptonBasisList. Not used for delta function basis sets.

referenceFwhmPix : float, optional

Passed on to lsst.ip.diffim.generateAlardLuptonBasisList. Not used for delta function basis sets.

basisDegGauss : list of int, optional

Passed on to lsst.ip.diffim.generateAlardLuptonBasisList. Not used for delta function basis sets.

metadata : lsst.daf.base.PropertySet, optional

Passed on to lsst.ip.diffim.generateAlardLuptonBasisList. Not used for delta function basis sets.

Returns:

basisList: `list` of `lsst.afw.math.kernel.FixedKernel`

List of basis kernels.

Raises:

ValueError

If config.kernelBasisSet has an invalid value (not “alard-lupton” or “delta-function”).
