Yes, the latest version of Sixtests gets the first 5 symmetric Zernike
coefficients (A00 - A80, needed to represent "fast" conics). 
Sounds like it will be useful to output them, I'll look into it.

"Angular" coefficients coming later, after a few more tweaks on
the webcam Hartmann reduction program.  The current software doesn't get
those coefficients, except for primary astigmatism (complex A22, which has
been a major headache, causing 2 years of tweaking ), it
just gets the surface and RMS, then generates a contour plot of the
deviations.
