Formula for hotspot angle in a reflector

Thank you very much for the update! I’m sorry that I was away for a while, mostly traveling and grading exams. Looks like I’ve missed many exciting updates!

(1) For the Map: do you have an explanation somewhere of how the hotspot size values are obtained? If so, I may have missed it. I would be very interested in comparing it with my ray-tracing model.

(2) I built an exact simulation of a parabolic reflector in 2D, from which you can get what the simulated beam looks like and some critical measurements like hotspot/corona/spill angles. I will post it in a separate thread and edit this comment to include the link. Play around with it and let me know what you think!
