astrometry tweak

I worked on the back end of the automated astrometry system: the part that tweaks up Sam's determination of pointing, rotation, and scale to a high-quality WCS. I keep remembering (and then forgetting) that the general solution to this "tweak" step is not trivial, if you want it to be hands-off but robust to all kinds of stuff you might get.

  1. Okay, you've got pointing, rotation and scale - what about twinkliness?
