Ok, Let the FUN begin 

For those that want "Just the Facts" here's everything I know at
the moment: http://lerch.no-ip.com/atm/2ndTry/lerchtest1.ZIP (300KB from RF
Royce)

For reference, Mr. Royce indicated that at the 0 Degree starting position,
Axis A was Up.  Also the 10th order polynomials are on the way if we need
them.

For those that want just the reduced data with out opening a web browser.

From the Quick Fringe Test Report: (with my math in {})

Unit = Waves
Wavelength = 633nm

RMS Wavefront = 0.145  {46nm Surface} PV wavefront  = 0.67       {212nm Surface}
Strehl Ratio    =  0.44
Astigmatism   =   0.40  83.3deg
Spherical = -1.43

So, we have astigmatism.  I imagine 0.4 is not a "good thing"

Question, given what we now have, can we work backwards and calculate what
Robo "should" have seen based on the interferometer data?

Take Care,
