It is 10:PM and last night's data is about half converted to star 
lists.  All the images are loaded, so it is just a question of the programs 
running to completion.  I could have it done by now but I upgraded to the 
changes that fix the problems around +90.  So far everything looks fine.

Sigh!  When one is running 6 cameras, there is something that is not 
"perfect".  For last night it is the TOM2 I camera shutter sticking.  This 
puts a small bump down the middle of the image.  I am not discarding this 
data.  I can not see any difference in the accuracy for such data.  There 
will always be something a little wrong, I think.  I have picked a set of 
parameters and I am sticking with them.  When the shutter is really bad, 
the image is thrown out.  The ones that are kept I can see a bump in the 
middle of the image, but it is of order the noise.  So I think it does not 
contribute a lot to the error.

I have one computer dedicated to the current data from TOM1, TOM2, and 
TOM3.  A fourth computer is working through the old data.  This way I do 
not get confused with which dark and flat set I am using.  So far, I have 
gone without any major analysis boo boo, I think.

About another 10 days of analysis and I will be ready to put the first data 
set on the data base.  I have possibly 10 million measurement pairs.  There 
are lots of variables in this data.  It remains to be seen how many of them 
are new.  I think that one will be able to find thousands.
