Analysis of Repeated Measurements: work-in-progress

[Stupendous Man <richmond@a188-l009.rit.edu>]

  Last week, during the week between RIT's Winter and Spring quarters,
I spent some time analyzing Mark IV images on "Data Disk 16".
These were repeated pictures of the same fields, taken by Tom Droege
on Sep 28, 2000.  I wanted to see how precisely one could measure
magnitudes from Mark IV frames.

  I'm still typing in my results, but you can find a draft of
Tech Note 76 here:

I've finished about two thirds of it, and I'm about to head home 
for the night.  If people take a look at it now, and send me questions
or comments, I can answer them in the final draft, which I hope
to release tomorrow.

  The part I haven't yet typed in is, of course, the most interesting.
As the introduction states, I found a noise floor at 0.005 mag or so.
I don't yet know its major source(s).
