Andrew's Trig Photon Work Log

This is where I scratch down things that I'm doing related to trigger egamma.

Getting and Reading Cosmic Data

  • get the data using dq2, you can see the list of datasets/files at /castor/cern.ch/grid/atlas/DAQ/2008//physics_L1Calo/
  • see the CosmicCommissioningReconstructionStatus twiki for info on setting up

How-To Add a New Chain

  • TriggerMenuPython/python/Photon.py add new chain to following lists:
    • l2photonFex defines the L2 FEX used for the chain
    • l2photonHypo defines the L2 HYPO used for the chain
    • efphotonHypo defines the EF HYPO use for the chain
    • l2_chains defines the L2 chain name and the L1 chain that feeds it
      • chain counter must be unique, ask trigger miester for possible values
      • set prescale=1 and passthroug=0, actual values set elsewhere
    • ef_chains defines the EF chain name and the L2 chain that feeds it
      • chain counter and pass through same as in l2_chains
    • l1_te, l2_te, final_te associates chain name with L1, L2, and EF trigger elements
  • TriggerMenuPython/python/EgammaSliceFlags.py add item to all lists
  • TriggerMenuPython/python/Startup.py add item to HLTPrescales

How-To Add a New Hypo Configuration

  • check out Trigger/TrigHypothesis/TrigEgammaHypo
  • in TrigL2PhotonHypoConfig.py make a new class for you new Hypo
  • in TrigL2PhotonFexConfig.py make a new class for the corresponding fex
  • put your new hypo in a chain as described above
