Re: [ATM] Mirror Round Robin and some in-house test results

[Dale Eason <atmpob@yahoo.com>]

James,
You beat me to the puch.  I too am preparing a similar
report on my Robo, my Bath Interferometry, and the
round robin.  I have been using mirror's B and C.

I found it interesting to also covert the round robin
data into surface profiles using FigureXP.  I have
done that with 6 of the investigators test results. I
was getting close to publishing the results. Foucault
testers used only 5 zones so the match is not as good
as robo to the interferometry.  However the causitc
test was by far the closest to the same shape and
matches to what you are reporting using robo.

It would be nice if we could get the error profiles
out of FigureXP in a machine readable form so that we
can plot them in comparison with other analysis.  A
simple list of radius and surface error heights would
suffice.
