Hi Dale,

Thanks, good stuff here! :)

Would a Monte Carlo analysis be a good thing to add permanently to
FigureXP? From my point of view it seems like it would...

Also, in the classic Couder mask eyeball Foucault test, I've never heard
any concern over Zonal radius errors mentioned. Did I miss this?

In my mind, I have a mental image where (assuming a mirror with a figure of
revolution) for each zone radius null there is a longitudinal KE position,
and for each longitudinal KE position there is a zone radius null.

With the above in mind, would a 'proper' MC analysis be constrained to only
longitudinal KE errors, Zone Radius errors, or BOTH???

Thanks,
James

PS. An idle mind can be a dangerous thing!
