Hey,

How about if I rather than random offsets to the data set, I mosaic the set
at specific locations throughout the chosen range (ra 1-355 x 5 degrees, dec
-15-15 x 5 degrees), and with each star, add a small (what size?) polar->x,y
offset random offset in both ra/dec.  This would populate the entire sky
with data, without overlap, and then jitter the stars within each frame (88
for both V and I for one set).

Later,
Rob
