Pardon, but I was explaining the size problem to a co-worker, and starting
musing about possibilities of the entire system...  These numbers might be
on the low side - any comments?

2000 stars per image

2 images per picture set
100 picture sets per night
100 nights per year

20,000 images to be analyzed a year
8Mb per image
160 Gigabytes of data per site to be analyzed per year

40,000,000 stars per site per year, and if we keep every observation in a
database:
26 bytes per star (observation list only)
1 Gigabyte per site per year of star data.

12 sites...
