Oh, I didn't mean to imply the documentation should be attached to the ticket, just that if the location of it (whether temporary or not) doesn't easily accommodate demonstrative figures, a few of the latter attached to the ticket would nice.
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.
Looks great Bob Armstrong. A few minor comments on the PR and a request for more test coverage (which can be pushed to another ticket if you'd like).
Hmm, I'm not sure I would. At least, I'd like to discuss in more detail what our longer term plans for the deblender and its documentation will be before agreeing to that. In particular:
