ACS image combination, LRG clustering

I hacked together the simplest possible HST/ACS image combination code in IDL, building on the distortions code I wrote earlier in the week. It is not yet checked into the astrometry module. I made this image of one of Schechter's favorite lenses, 1RXS J113155.4-123155, using my new code and some public ACS data

I gave Morad comments on parts of his small-scale LRG-LRG clustering paper.

    You were right. It does make a big orange ball.

    That big orange ball would be right in the center of the image if #%$@ ACS images had correct WCS.
