  2. TOF QA • Code in $ALICE_ROOT/PWG1/TOF • Run considered: 149102, 152513 • Events selected: kMB • Track selection (in the TOF QA task!) • esdTrackCutsStd2010->SetMinNClustersTPC(70); • esdTrackCutsStd2010->SetMaxChi2PerClusterTPC(4); • esdTrackCutsStd2010->SetAcceptKinkDaughters(kFALSE); • esdTrackCutsStd2010->SetRequireTPCRefit(kTRUE); • esdTrackCutsStd2010->SetRequireITSRefit(kTRUE); • esdTrackCutsStd2010->SetClusterRequirementITS(AliESDtrackCuts::kSPD, AliESDtrackCuts::kAny); • esdTrackCutsStd2010->SetMaxDCAToVertexXYPtDep("0.0182+0.0350/pt^1.01");//selects primaries • esdTrackCutsStd2010->SetMaxDCAToVertexZ(2); • esdTrackCutsStd2010->SetDCAToVertex2D(kFALSE); • esdTrackCutsStd2010->SetRequireSigmaToVertex(kFALSE); C. Zampolli

  3. Marian’s plot, tTOF – tExpPi Tracks pointing to the vertex Run 149102 TOF raw times TOF raw times, matching window subtracted, T0Fill subtracted, calibrations applied From Online DQM, noise not updated (some noisy channels included) C. Zampolli

  4. Marian’s plot, tTOF – tExpPi ITS requirements Run 152513 TOF raw times TOF raw times, matching window subtracted, T0Fill subtracted, calibrations applied C. Zampolli

  5. Conclusions • Same behavior as that found by Marian, even if applying quality cuts • Less peaks than the number of bunches could be due to different trains in the same orbit C. Zampolli
