  Interesting results John. Did you compare these results
to the MAOFD predictions? Just wondering if the MAOFD
method of adding the geometric and optical blurs orthogonally
gives the same results.

  It does seem that f32 might be a useful aperture in some
cases though the smaller ones are just to fuzzy.
