Re: [ATM] PLOP Calculations

[Mark Holm <mdholm@telerama.com>]

The most complex cells preprogrammed in Plop have 27 support points.  
Depending somewhat on the mirror thickness, it is possible that 27 point 
support will not be sufficient.

I have a 54 point layout designed by John Dudgeon.  Plop can optimize 
this layout for your mirror.  We need the rest of the mirror 
specifications:.

glass type
diameter
thickness
focal length
secondary minor axis (diameter)
central hole diameter (if any)

The Plop setup is at  
http://pong.telerama.com/~mdholm/atm/cells/54point.html 

The only trick with this cell is the large and potentially confusing 
number of dimensions to be specified.  There are 4 or 5 different 
triangles, some of which are not even isosceles and they are not at 
obvious angles..  I am not at all sure I want to try writing out the 
specs for this cell.

It is possible that a more symmetric, and easy to specify cell would 
work.  This one may take some work.  A 46 inch mirror is worth the work 
though.
