How to get trigger information in xAOD

• Twiki Trigger Analysis Tools
• Twiki Trigger xAOD Tutorial
• Simple codes to run on xAOD :
  • /afs/cern.ch/work/s/smwang/public/triggerHbb/trigtut_example
    • some codes in trigTutTest/util (e.g. "simpleshell" will print out number of times a trigger has fired, and make plots)
    • see setup.sh to set up the working environment
    • example to run "simpleshell" : simpleshell AOD.pool.root
  • /afs/cern.ch/work/s/smwang/public/triggerHbb/trigger_xAOD
    • Example code to read MET at L1/HLT level, make MET trigger efficiency turn on curve
    • to run
      • go to MyAnalysis/util directory
      • >testRun
      • Outout root file is in submitDir directory
