Information available

  • The TEM trigger diagnostic information provides trigger information on CalLo and CalHi per each layer end.
  • From Sasha:

    The code example for accessing CAL diagnostic info I can recommend you is the algorithm from calibGenCAL package used for trigger thresholds measurement:
    /afs/slac/g/glast/users/chehtman/calibGenCAL_analysis/calibGenCAL/calibGenCAL-05-06-00/src/lib/Algs/LPATrigAlg.cxx
    The method
    LPATrigAlg::fillTrigBitArray()
    just extracts CAL trigger bits from a digi file and puts them into some local structure.

  • As a reminder, CalLo is at 100 MeV and CalHi at 1 GeV.
