The matchBackgrounds.py script was an initial attempt at matching multiple warped visit-level images to a given reference image. Taking the difference images between the reference and each subsequent image allows for each of these images to be modified to match the background of the reference image. These images may then be stacked (coadded), and a single background estimation made on the combined (and, importantly, deeper) coadd image.
The existing matchBackgroundsTask has not been utilized in some time. This ticket aims to explore the feasibility of resurrecting this code base, with a mind towards testing on HSC in the near-term.
