astrometry hypotheses, environments literature

Sam and I discussed some of the steps involved in the "resolve" part of automated astrometry, where we have to decide among many computer-generated hypotheses about where each field is pointing and its rotation and scale. We think that a single coincidence among quads will be sufficient, but there are issues for finding even that coincidence (what's a coincidence?).

I got comments on the post-starburst environment paper from Tucker, Knaizev, Goto, Humboldt, and Morad. These comments were great; in particular they pointed out that I have completely ignored an important and relevant literature, much of it emanating from SDSS itself. I should hang my head in shame, but in fact I am happy that everyone is doing my work for me.
