[ATM] UltraThin on 3 pads and 2 pegs

[Dale Eason <atmpob@yahoo.com>]

Mirror stand tilted back 45 deg.  Three carpet pads at
125 mm from center.  Only astig, coma and spherical
terms are turned off.  The mirror surface was not
removed from the data.  It is just swamped by the
distortion of the supports.

Grey color is area within 1/4 wave tolerance.  Height
above grey of left bulge is 1/4 wave on the surface. 
Left pad is under an upward bulge on the surface so it
is height than the others.

Pegs cause major rise.  I'm surprised that top is high
since gravity is pulling it back I would think.

I will be trying various supports.  If anyone has one
for me to try and it is within my skill and budget I
will try it.

Astic levers are probably beyond my skill and budget. 


Next I will move the pegs closer together.  David says
30 deg separation improved his cell.
