   Ball will apparently gleefully sell you a system, but when I talked   
   to one of their engineers some years ago he didn't want to be any   
   more specific than that - evidently they figured that their   
   details were proprietary. Hint from debriefing the Astro project'   
   scientists - be really sure of your star catalog's lineage and   
   the camera's wavelength span of sensitivity if you want to include   
   an intensity cut for star IDs.
