[ATM] oslo edu secondary mirror data input question
Greetings,
I'm trying to input specs for a mak-newt design into
oslo edu and the ray trace stops at the secondary
mirror and does not reflect back to the image plane.
Spent a couple of hours going through the docs but
didn't find any examples on how to set up the
secondary mirror.
Was hoping someone on the list would have an example
for how to do this. I inputted the same design into
ATMOS with no problem but OSLO seems a bit tricker.
Thanks,
Dave Janello
