[ATM] Flats page

Hi,

My apologies for sending yet another email to the list this morning.

I just finished up refiguring a couple of flats, and I've put up a new 
web page describing the work.  First was a 10" flat, and second was 
the 5.5" minor-axis diagonal mirror used in our 30" F/3.8 scope.  You 
can find the page by going to

   http://bi-staff.beckman.uiuc.edu/~melockwo/index.html

and selecting "A Tale of Four Flats - NEW" under the "Mirror Making" 
heading.

There's a picture that shows the cooling of the diagonal after it was 
worked - it changes shape quite a bit.  Most importantly, the 
secondary-induced astigmatism that we had in the 30" should now be 
eradicated.
