Calculating incidence angles to receivers

[abhargavashah]

Hello!

I had a question regarding the eikonal.c file in pyekfmm: I believe the calculation of the takeoff angles from the source occurs in line 914 (dip[i1+i2*n1+i3*n1*n2+is*n1*n2*n3]=atan2(sqrt(grad1 * grad1 + grad2 * grad2), -grad3) / cRPD;). I was also hoping to be able to calculate the incidence angles to the receivers. Would you by any chance know how best to modify or add to the current code in order to do this?

Thank you! I greatly appreciate any insight you might be able to provide!

Hi, abhargavashah,

Received. I'll help you solve the problem. I just returned from vacation, and work has piled up. I'll return with a solution ASAP.

Thanks, YC
