Jan,

Here's what I get for results using these three programs (Sixtests, FigureXP, 
Foucault Test Analysis)

                          Sixtests    FigureXP    FTA
Strehl                 0.891        0.875        0.781
Surf RMS nm     14.9          15.9            41
Surf s(RMS) nm    3.3            4                5.7
Best Fit Conic    -1.052        -1.06        -1.0145

While I trust Sixtests the most, FigureXP seems to be Provide a simular answer. 
However FTA is substantially different, and I have no Idea why.  All three 
programs were feed the same data.

Historicly Sixtests and FigureXP have provided results on different optics, 
while not exactly the same, the results were substantially simular.  However, I 
can not precule that both Sixtest and FigureXP could be inaccurate, but....

Take Care,
James Lerch
