1. Discussion of GEANT4
Checked x-y hit distributions at various location using virtual planes in the simulation. Tried to track back the origin of the blob structure shown on the detector plane. Something weird shown at the Dipole exit. Hit plots look rotated, but it's because of Solenoid field.
Asymmetric hit distributions on the left and right hodoscope planes when coincidence hits are required. May come from asymmetric phi range in the generator.
Quad magnets seem to be not set well. Many particles hitting 3rd/4th quad shown from both G3 and G4. Stick with the same setting with Bill until we have better ones.
Suggestions: try check plots with Solenoid OFF. Set generated phi range symmetric.
