Re: [ATM] oslo edu secondary mirror data input question

[David Janello <djanello@yahoo.com>]

Hi Michael,

I input the Setup->Field Angle->1.0 and it works, the
spot diagrams appear over the 1 degree field.

When I go to optimize, I select Optimize->Generate
Error Function->GENII Ray Aberration and then select
the default values.

Then I go to the Variables input screen, set the
surface type to CC (conic constant), set a min+max
value of 0.0 to 0.01.

According to your instructions I need to call the
Optimize then Iterate commands, but I don't see a menu
or choice to do this.  Do I need to call a command
line cmd to do this, I tried geniiops in the variables
window but nothing happened.

Thanks, this is saving hours and hours of time,

Dave

This works, I can now view the entire spot diagram
across the field.
