[ATM] [interferometry] Igram

[Vladimir Galogaza]

Wayne,

>Question, what tool are you using to do this analysis?
 ( Intensity profile of interferogram at one diameter)

I was using (in chronological order): 

1)  Advice to all ATM from Michael Peck to try (free) "R" programming language
      where to find it and how to download it.

2) Extensive tutoring in "R" language by Stephen Koehler ,I am much indebted for.

3) which enabled me to write small "R" program for this purpose. Just couple of lines,
    which sometimes reveals  some interferogram characteristics better than
    visual perception.

Wealth of what Stephen and Michael already have in their "R" program treasure boxes, highly related to what ATM should be interested in, is still to be discovered by most of gents on the lists.
Why it is still not exploited is similar puzzle to me as why the Bath interferometer
was forgotten since published in 1973 and used practically only  by Wolfgang Rohr.
It has to wait 20 years to be revived by David Rowe and his pioneering fringe tracing 
program. Since then Dale Eason provided famous OpenFringe and Michael Peck
his PSI analysis program. All mentioned programs are free, authors alive, well
and willing to help. Small but potent number of ATM decided to give them a chance and what they achieved is proof that interferometry for ATM is not exotic extravaganza but mature testing method.
