Taking into account photometry that is possibly contaminated #55

Open jpdeleon opened 9 months ago

jpdeleon commented 9 months ago

I checked the librarian module and the catalog cross-matching is based on position. Given Gaia sources, can the Librarian class include a logic where a given photometry is excluded (or at least flagged) if there is any unresolved sources near the target? Right now, my heuristic is re-run ariadne until I discarded all photometries that deviate too much e.g. >3-sigma from the best-fit SED.

I had planned on doing some sort of further quality check on the photometry but haven't gotten around to it. If you have an idea of how I could identify unresolved targets near the actual target, I'd be happy to hear it!

I don't have a specific solution but today I came across this paper (See Sec 2 & 3.1) which discusses how they take into account contamination in cross-matching.
