[ATM] Ultrathin lateral support at 30 deg.

[Dale Eason <atmpob@yahoo.com>]

David wanted me to try the lateral support pegs at 30
deg apart.  He had better luck with them there.

I will not post pictures this time.  I tried it.  The
effect is not much better.  However if I didn't
carefully place the mirror it created about 4 times as
much X astigmatism because the pegs can push the
bottom of the mirror up even better than when at the
90 deg position.  I did learn from that experiment
that the high edges out past the pads were not caused
so much by the lateral support but from the pads
themselves.  See my PLOP post.

Tomorrow I will try Richard Schwartz's idea of hanging
it by tape attached close to the center.  This will be
to try and eliminate the lateral support problems.
