1. Make GigE camera(s) work: full resolution, high dynamic range (all the bits), lower frame rate.

1. Explore required network bandwidth: how many GigE cameras can we have on single hub?
2. Some image processing: beam sizes, beam centroids, total power, diffs,...
   1. 2-D Fit determines beam centroid, width, and intensity
3. Image archiving: 1/sec for the past 5 minutes, 1/minute for the past day, 6/hour forever
4. Image compression? Just record the diffs?
   1. TIFF files are roughly 0.5 MB per image, plain text is roughly 3.5 MB per image
   2. Normal file compression (zip compression in OS 10.5) compressed files to roughly 1/4 their original size
   3. At above rate of archiving and ~15 cameras per site, this is ~90000 images for one month and another ~67000 images for each following month. To fit a year's worth of data (~827385 images) on a 1 TB drive, this requires that each image be compressed to ~1.2 MB. Thus, the basic TIFF format is reasonable but could likely be improved upon.
5. Use TM spots to do auto-alignment.
   1. 2-D Fitting is too slow, center of mass method easily fast enough but may not be accurate enough
   2. Need to look into EPICS control methods
6. Port Josh's beam scan stuff to use these cameras.
7. Buy more cameras.
