Below are the reconstructed events with the solenoid on and off for 1k events

Raster in Z

Since the LUND files are not currently operating correctly, I will use a different method to raster in Z. I will use the GEMC command line to reduce the radius of the target to 0 cm and randomly place vertex positions along Z (like a line target). The command line for GEMC is shown below along with the gcard when the solenoid is off:

Raster in XYZ

For this simulation I rastered the beam in the XY plane around 1cm, and z was rastered +/- 3cm. Below are the differences in the the generated and reconstructed angles for when the solenoid was off:
