Morning all,
        A few months ago I found the following link
https://sourceforge.net/projects/foucault/ which contains a foucault
analysis piece of software. Its a 14mb download but is platform independent
being written in java with a gui as well. You need to take a sequence of
jpgs from inside ROC, at the roc and to the outside of ROC. I take them
every mm from about -5mm to about +10mm. You then load the images in to the
program. It then works the nulls out and analyzes the results. I don't know
if anyone has used this so I can't vouch for output. In my case though I've
tested three mirrors with it and it SEEMS to agree with my (admittedly
poor) interpretation of the mirror.


Cheers
