I discussed Quintero's clustocentric results and strategy with Quintero, Blanton, and Berlind on a phone call.
Morad kicked my butt on computing nearest-neighbor statistics for the K+A galaxies (and, indeed, everything in the VAGC), and he finds that there is evidence for tidal triggering of post-starburst galaxies. So the "environments of post-starburst galaxies" project has a positive result. Time to start writing! We still need to do the clustocentric distances, but the upshot of the Quintero call is that Quintero is making us the FITS file we need.
