July 18

Today was much better than yesterday. Early in the morning I figured out how to use Hastrom to allign the far UV, near UV, and optical images. Although I now understand the process, my results were not quite what we had in mind. Because of the differences in the images between the telescopes the compiled images are either zoomed to far out to get good detail on the galaxy, or too close, where the UV images have very poor resolution. I spent much of the day trying to discover a better way to compile the images and testing them. I finally got to talk to Jake about and hour ago and he recommended trying to use the digitized sky survey images instead of the Hubble Telescope images. He also mentioned looking up some smoothing and un-sharp mask commands for IDL to help the detail of the images. The good news is that I already downloaded the digitized sky survey images, the bad news is that I have to start over again with these new images. At least I know what to do Monday next week!
