[ATM] which Bath version

This is very interesting question. People are using either original or right 
angle version
but as far as I know nobody used both with equal intensity. Only such person 
will
be qualified to answer your question with competence.

I am using only right angle version, as most second generation does.
By "second generation" I mean post-Rowe  ATM attempts at interferometry.
First generation, represented typically by  W. Rohr contribution, used
original version. Absence of free analysis programs and computers was
quite a handicap for the first generation. This is no more a case .
In my case inertia was (is) at work, but now, after you have asked a 
question,
I am motivated to find an answer, and having necessary hardware, will give 
it a try.
Have a patience, please (lot of).

And have my best regards
Vladimir.
