Introduction

See index in AmnonHarelDataMixing

Aborted attempt to test Mike's DataMixer, circa June 15th, on the files he provided me. Goal was to see overlay work with active overlapping digis in data and MC (event overlays without overlapping digis look fine, see AmnonHarelDataMixingRound4a).

Conclusions

How I got there

• work area: /uscms/home/aharel/CMSSW_3_1_0_pre9/src/RecoJets/JetAnalyzers
  • similar to previous CMSSW_3_1_0_pre1 work area. Introduced, from ~aharel/test/, src/AHtest.cc, interface/AHtest.h, BuildFile
• data area: contains both .log and .root files /uscms_data/d1/aharel
• Mike's files: (excert from his email) /uscms_data/d1/mikeh/MixData_RAW2DIGI_RECO.root which is the "standard" HCAL noise file we used before overlayed on /store/relval/CMSSW_3_1_0_pre8/RelValQCD_Pt_80_120/GEN-SIM-DIGI-RAW-HLTDEBUG/STARTUP_31X_v1/0005/F076816C-504D-DE11-A394-001D09F253C0.root. This time, the full DigiToRaw simulation is done. This is with the HCAL information taken from the SimHits for the MC signal.
  • event dump with (work area) gdO9.py in (data area) gdO9.log
    • no hcal digis (XXXXDataFramesSorted, with XXXX=ES(?), HBHE, HF, HO, or ZDC )
  • looks like data file is: /uscms_data/d1/mikeh/promptRecoHCalNoise.root
• my MC: QCD3event.root contains 500 events from the same MC file Mike used. Created by copyQCD3.py.
  • dumped content with gdQCD39.py --> can't find the "pCaloSimHits" Mike mentioned. Unless these are: PCaloHits + "g4SimHits" + "HcalHits" "HLT"
• my non-collision data: started with a copy of Mike's file in my data area.
  • dumped content with gdData9.py --> found the digis (HBHEDataFramesSorted "hcalDigis" "" "Rec"), but no rec hits...
  • preparing data with prepData9.py (had ro repeat reco.) --> preparedData9events.root & log file prepData9.log
  • dump for plots in prepData9.root
  • set all threshold to 0 so all plotting information is available for no-collision data
• notes on building the mixer:
