-- AmnonHarel - 23 Feb 2009

Introduction

Changed:

See also AmnonHarelDataMixingRound2 (Mike's "V2" and "V3" files) and AmnonHarelDataMixing.
>
>
The "V4" files tested here are not that interesting. See page AmnonHarelDataMixingRound4a for the interesting tests. Earlier rounds are in AmnonHarelDataMixingRound2 (Mike's "V2" and "V3" files) and AmnonHarelDataMixing.
  Testing Mike's DataMixer, circa 20 Feb, with his "V4" files. Goal was to see a plot of HPD discharge noise overlayed near / over MC signal.
Added:

Stopped when we realized they they contain the same problematic CRAFT data as the "V3" files.
 

Conclusions (on the overlaying process, and reconstruction)

  • Non-collision data events: /uscms_data/d1/mikeh/promptRecoHCalNoise.root (from run 68021)
    • examined using gdData4.py -->
gdData4.log
  • this file contains calorimeter digis, but no reco. calo jets
  • raw2digi, reco & translate to my sc.c format using prepData4.py --> prepData4.log, prepData4event.root (in CMSSW format) & prepData4.root (in my format)
    • Finally update to a CRAFT global tag: CRAFT_30X::All. Still pretending the magnetic field is 0 though (don't really care).
    • Looking for anomolous events:
      • #14 (i.e. 645870) looks odd at HB-, 70. Very long low signal (like RBX) but only a few channels in the same HPD.
      • #28 (i.e. 1082063) is notable for having a very short energy deposit (confirmed by ECal, so probably a malformed muon deposit)
      • #364 is the most HPD-discharge like, and there's also no ECal energy. Yet, it just looks like a muon hitting HCal.
      • all the rest look like uncorrelated noise + muons.

    • Non-collision data events: Turns out the wrong events were used (run 70664 instead of 68021)
     
        • Not sure why the raw2digi step is needed. Without it complains about:
                  Looking for type: edm::SortedCollection<ZDCDataFrame,edm::StrictWeakOrdering<ZDCDataFrame> >
