Attendees: Ashot, Chao G, Chao P, Dipangkar, Maxime, Weizhi, Xinzhan, Eugene, Mahbub

Maxime:
Comparison of simulations Maxime/Weizhi
- minor differences from esepp generator (1%), still to be investigated
- rise of discrepancy till 10% from 2 degree after geant4 process
  -> task: swap files, check geant4 version, geant4 env files
- really big discrepancy after digitization but might be due to cluster energy cut

Xinzhan:
- GEM efficiency for empty runs shows big drop till 10% at large angle
- working on cosmic rejection to improve efficiency measurements
