Here are a couple of examples of what the algorithm does from a list of merging galaxies in HSC that are known to have their flux underestimated as compared to SDSS. (You can find a list of these in DM-8139).
In the following pictures I have labeled
- blue "x" = peak the deblender thought was a PSF
- green "+" = peak that is not a PSF
- purple "o" = objects identified as having their template degenerate with another one.
- red "x" = object that had underestimated flux compared to SDSS
Here are a few examples of cases that look like this is helping to not shred galaxies
Here are some examples where objects were identified as having a degenerate template, but perhaps should not have been.
