GCN, Willman data, tidal trigger

I made SDSS imaging mosaics and finding charts for Eisenstein's GCN Circular on GRB 050509b.

I finished checking all the Willman astrometry and it is all completely fine, to my eye. I noticed some "data features" that made me suspect the cross-talk calculation (again!).

I worked out the steps involved in the small project Morad suggested, of looking at close neighbor separations as a function of A/K for the post-starburst galaxies, to see if they are plausibly tidally triggered.
