[ATM] Ronchi quiz

[Dale Eason <atmpob@yahoo.com>]

I thought ronchi users might like to take a stab at
the this image.  It is from a 16 inch mirror in
progress. It is pollished out.  Can any tell me what
they think is going on?  I know and will tell you in a
few days.  I wonder if anyone has ever seen anything
like it.  The position of the ronchi screen is very
close to the ROC.

A clue is in the file name.  One other on the list
might recognize the image.

Next is a Foucault image taken at the same ROC.  It
may help you to interpret the image.  The main purpose
of the foucault image is to show that it is a mirror
eventhough it has many faults.
