galaxocentric distances, ACS thumbnails

Morad and I fixed bugs in the galaxocentric distances calculation (we were being too clever) and discussed the result. It appears that tidal triggering for K+A events is almost certainly ruled out. There is one more test to perform, which is to simply look at the overdensities on a 1 Mpc scale, but I don't expect it to give different results than the nearest-neighbor distances.

I cleaned up some of my ACS thumbnail cutout code (hogg_acs_cutout in astrometry/pro/acs) and shipped it off to Lexi Moustakas for testing and experimentation.

  1. I did some experimentation with my thumbnail once when I was in eighth grade. Man did that hurt!
