Dear Geant4 users
I would appreciate it if you could make it more clear for me.
How do I make calculations in /gps/direction macro file?
In what types of examples definition of /gps/direction is needed?
Here is my example: Reflectivity
Source: a rectangular source of x- rays with constant energy
Type of experiment: studying incident xrays on a constant target from 0 to 2 degrees ( with 0.1 degree increment) and measuring the number of photons after the reflectivity process.
Thank you in advance and I look forward to hearing from you.
