  • tool for examining global tags: twiki page

20-April-2009 Monday


  • Tim explains the silly error we made for the simulation and unpacker.
    • Claim is very low efficiency for endcap muons b/c the packer does not set two bits correctly.
    • Tim and Victor fixed this quickly by removing checks of those bits in the examiner.
    • But why didn't we catch this with CSCValidation? Andy has plots for 227, 310pre3, pre4, pre5...
  • DT Barrel Workshop starts this afternoon
  • 228 relvals are available: HN
    • Andy did the validation:
      1. No important differences w.r.t. 227.
      2. he fixed the ranges of histograms. smile
      3. rechit (X,Y) plots have strange lines of points for ME1/1 Not there in 227.
      4. X position (within strip) has distinct bowl shape...
      5. normalized chi-squared looks funny for ME1/1a.
  • Andy checked the 310pre5 RelVals:
    1. ME4/1 seems to be missing! But it appears in the efficiency plots !?! And gas gain plots !?!
    2. all of ME4/2 is simulated - this is wrong.
    3. some histogram ranges need to be extended
    4. rechit efficiency is lower for ME+2/2. - probably a statistical fluctuation.
    5. pedestals are narrower - due to changes we made in noise matrix.
    6. N hits per segment is different - is this due to pruning?
    7. gas gain is higher.
  • Jonatan finds higher yields for tracker-volume-constrained cosmic MC samples, as expected: HN
  • Intriguing study by Andy, showing poor performance of parabola and weighted average for rechit time: plot
    • Tim had observed a systematic shift in the timing, too.
    • Stoyan has pointed out a double-peak structure.
  • Send message to L3 list asking to start meeting at 4pm so that it can last longer.
  • Review slides from last alignment meeting
    • very nice job by Samir. Large Z shifts from nominal, O(5-15 mm).
    • Increase in assigned alignment errors. How to update the APE's in the data base?
    • perhaps Jim & co should use these results for ME4/2, too.
  • Action items from muon-HLT meeting: HN
  • Stoyan's diagrams for ALCT and CLCT:

    • Gavril A. Giurgiu observes a crash. (Tim responds.)
    • Oana gave lots of good details in her talk.
    • Need a mathematical test to identify when noise matrix elements are bad.

    • She also tried to fix the bad matrix elements for ME+2/2/28.
  • What are the right global tags? Nikolai is asking.
  • HLT
    • seems there are problems. Ask Ingo.

    • un-ganging of channels in ME1/1:
      • digitizer and cscrechitd OK in principle
      • unpacker not so easy: too many strips. (I don't quite see the problem.)
      • (fake) calibration constants - where should they be stored?
      • need run-time flags which means updates to cfg files which means HLT headaches.
      • This all sums to a non-negligible amount of work - to be done in 2 weeks!

    • understands message logger - wants to clean up unpacker
    • confirms that the missing strips and wires really are not present in the raw data buffer
    • points out that events have lots of zeros, etc. - are too fat. Discuss this at Rice mtg

Global Tags Alignment - information from Jim

2) beam splash/halo:     CRUZETALL_V6
3) EW35 (37):            CRAFT_ALL_V4

David answers some questions concerning payloads:

  • (real) dead chamber list is in 220 as an sqlite file, and has been tagged for 300 CSCBadChambers_realCal
  • cruzet3 tag is used for the first reprocessing, for pedestals, gains, cross-talk and noise
  • realCal values need better validation before they can be used.

    • Oana says she looked at them. What are the right values, what should we expect?
    • Igor quotes Tim as saying that negative values are a problem.
    • Igor says there are many zeros.
    • Oana asks - why does MC crash? And proposes to do some validation with MC.
    • Tim identifies parts of the digitizer which require positive value for off-diagonal noise xtalk matrix elements.
      • The digitizer uses the pedestal width to set the scale of the noise. Must not be zero.
      • Tim says David Futyan has reverted to old CSC conditions.
    • Igor says Real data inside CSCDBNoiseMatrix_mc look more close to what was in MTCC.
    • massive confusion about what is named what.

4-Dec-2008 Thursday

  • Yesterday Riccardo asked for help to track down the reason for the poor CSC SA muon resolution. 2_0_10 vs 2_1_0.
    • I think we changed the digitizer at this time, to lower the charge and adjust the noise.
  • Nice presentation by Stoyan. We need to exclude the unpacker as the source of the trouble.
  • Libby's presentation was not very convincing. Need more juice there.

    • ssh -Y your_username@cmsusr2
    • ssh cms-data-lookarea
    • ls -ltr /lookarea_SM/
    • (Unfortunately one needs an account on cmsusr2 which I do not have.)
  • tip from Andrea (7226 control room) to compile with integration release: scramv1 project CMSSW  CMSSW_2_1_X_2008-09-07-1000 (and a list of available builds is scramv1 list CMSSW)
  • DQM global run registry:

6-Sep-2008 Saturday

  • 50k beam halo MC completed! /castor/ where nn=01,02,...,10
    • unfortunately, no CSC DIGIS. frown
    • I expanded the of keeps and made a 1k test - looks OK now. And can be analyzed successfully by CSCValidation.
    • Rework the python scripts and resubmit.
  • a tip from Boris Mangano: In order to compile quickly,
scramv1 b -j 'n' 
where 'n' is the number of CPUs on the machine you are logged in. If you log to a 4-cores machine which has not other jobs running, you should be able to compile order of 50 packages in few minutes.
  • set up filter py script for IGUANA
    • focus is on CSC's - I assume other detectors already in (or we can use reconstructionCosmics)
    • sequence is: csc local reco, cscSkim, cosmicMuonReco
    • works on data from CRUZET4
    • try it on beam halo MC:
