FW: ATM Primary mirror support in the horizontal plane (Nastran plots)

Clive, Richard,

Does this simulation suggest that the largest deformation is 
in the order of 4E-6 micro inch? 
Or should it read 4 micro inch, which seems to be more realistic.
What do these numbers mean in reality? The 4 micro inch 
corresponds to about 1/5 lambda, but as in-plane deformation. 
What effect does this deformation have on the light 
reflection; is it also in this order? My gut feeling says it 
should be a lot smaller than that.

Can you please detail on this? Thanks!
