Then, somewhat more esoteric:

    http://users.rcn.com/rflrs/Ptz09-43x.atm   ATMOS input file
    http://users.rcn.com/rflrs/Ptz09-43x.len   OSLO input file
    http://users.rcn.com/rflrs/Ptz09-43x.txt   TEXT prescription
    http://users.rcn.com/rflrs/Ptz09-43x.zmx   ZEMAX input file

The zonal correction is now better.  The Visual Strehl picks up
more.  The best part, though, could be the removal of the first
air-space -- two less air-glass surfaces.  The field is now
also flat.

Note: The "poor man's special short flint", N-KzFS8, was not in
my ATMOS catalog.  It is entered as direct refractive indices.
It is possible that it may not be in ZEMAX catalogs -- I picked
up a more current ZEMAX catalog from the Schott website.
