Re: ATM update on foucault/interferometry difference

["Bob May" <bobmay@nethere.com>]

I tried changing the F-stop on the lens and it didn't make any real
difference.  I'm going to do several things next time that I didn't do this
time.  First is that I'm going to try my tester (the tester that I've been
using is another tester that belongs to the guy at whose house that we are
now meeting as the Univ. has changed the policy for parking on weekends) and
see if anything changes and then if that doesn't work, build a tunnel to
drop the amount of stray light (the tester is in a garage that has all kinds
of skylights and thus it is impossible to get a dark room in the middle of
the day) to see if that fixes the problem.
