sourceToFootprintList

lsst.ip.diffim.sourceToFootprintList(candidateInList, templateExposure, scienceExposure, kernelSize, config, log)

Convert a list of sources for the PSF-matching Kernel to Footprints.

Parameters:

candidateInList : TODO: DM-17458

Input list of Sources

templateExposure : TODO: DM-17458

Template image, to be checked for Mask bits in Source Footprint

scienceExposure : TODO: DM-17458

Science image, to be checked for Mask bits in Source Footprint

kernelSize : TODO: DM-17458

TODO: DM-17458

config : TODO: DM-17458

Config that defines the Mask planes that indicate an invalid Source and Bbox grow radius

log : TODO: DM-17458

Log for output

Returns:

candidateOutList : list

a list of dicts having a “source” and “footprint” field, to be used for Psf-matching

Raises:

RuntimeError

TODO: DM-17458

Notes

Takes an input list of Sources that were selected to constrain the Psf-matching Kernel and turns them into a List of Footprints, which are used to seed a set of KernelCandidates. The function checks both the template and science image for masked pixels, rejecting the Source if certain Mask bits (defined in config) are set within the Footprint.
