See index in AmnonHarelDataMixing

Testing Mike's DataMixer, circa 1-19 Feb. Goal was to see a plot of HPD discharge noise overlayed near / over MC signal. The closest we could get with "version 3" of the test file (due to reasons described below) is: sav3mix24.gif

To understand this event, look at the attached pure MC, overlayed data, and the HPD noise analysis of the data and the mixed MC. The HPD analyzed is the one chosen by my HPD discharge noise ID, which uses only the geometry of the HCal energy in eta-phi space.

Conclusions (on the overlaying process, and reconstruction)

  • made two new reconstruction configs recoMixed_cff.py and RecoLocalTrackerNoZeroSuppression_cff.py (exact locations below) to be able to reconstruct overlayed data
  • this CRAFT data should not be be mixed - onward to V4 in AmnonHarelDataMixingRound4


  • work area:
    • Old one is /uscms/home/aharel/CMSSW_2_1_10/src/SimGeneral/DataMixingModule
    • New one described below /uscms/home/aharel/CMSSW_2_2_3/src/
  • Mike's notes on reco-ing:
    • CMSSW 2_2_3 was used for making the overlays, but caused problems when reco-ing MC.
    • He then generated some new MC for 2_2_3, and that's what is in the _v3 files .
    • Mike's reco config is /uscms/home/mikeh/work/CMSSW_2_2_3/src/SimGeneral/DataMixingModule/python/datamixertest_RAW2DIGI_RECO_STARTUP.py
      • But that one doesn't use the mixer output !?
      • this one, in the same location, does DigiRecoExampleMC_STARTUP_cfg.py, and it looks to do so exactly like my config from round1, so I'm using that /uscms/home/aharel/test/recoMixed_cff.py.
    • In 2_1_8/9, Mike "had to turn off Preshower5x5 Clustering in the EndCap". This is not an issue for my test.
    • Mike also run into the problem of the siStripZeroSuppression, since the mixer (currently) outputs SI digis that replace the zero suppressed digis, instead of the lower level virginraw digis. I copied and renamed his config to /uscms/home/aharel/CMSSW_2_2_3/src/SimGeneral/DataMixingModule/python/RecoLocalTrackerNoZeroSuppression_cff.py
  • data area: contains both .log and .root files /uscms_data/d1/aharel

    • used copyQCD2.py to copy 500 events into QCD2events.root
      • odd, only 450 events there.

      • examined using gdData2_2_3.py --> gdData2_2_3.log
      • this file contains reconstructed jets, but no calorimeter digis
      • translated to my sc.c format using prepData2.py --> prepData2.log
      • no clear HCal anomolies in the events I translated (first 100). Most suspicious (no EM energy nearby) are #79, #233, #343 (physical?), #454, #455, #460. The corresponding CMSSW event #s are 21017408, 21029876 (--> MC#24), 21038460, 21045212, 21045448, 21045688.
      • physical looking energy:
        • EM energy nearby: event #214, #385, #405, i.e., 21028404, 21040920 (--> MC#176), 21042488 (--> MC#196).
        • muon shower? in event #216, i.e., 21028474 (-->MC#7).
      • all the interesting (hardest in event and noise-like) energy is in the first 3 digis - what trigger and/or noise type is this?
      • Dima 's warning: this looks like a high rate run (verified in run registery) with only a few time slices read out, and with aggressive 0-suppresion.
    • /uscms_data/d1/mikeh/promptrecoCosmicsDigis_2_1_8.root
