I think Arne's site will be about 3x more productive than the
others with are at poorer sites.  So all six sites would
generate 8/3 * 154M V&I star detection pairs or
800 million detections per year.

Last week I applied Tom's numbers and came to the almost exact
same result:  That we will fill four 20GB drives every year.
(or 3 x 30GB drives the second year and 2 X 40GB the third year)

The one I krrp at home is about 800MB.  It is a subset of
the one at rit.edu  Maybe 2/3 it's size?
