So far we have two different calibration files, namely for CalibRunNo=6418, and CalibRunNo=8931. The last one is probably the best option for the last pp running and for some period of dAu, but concerning the tuning parameter which we have right now in the db (globalTdcOffest and driftTime), 6418 should be used for run numbers < 8931 and 8931 for run numbers >=8931. We have a problem with calibration for runs > 8966 - the resolution is rather bad. Maybe it is connected with a comment which was put in the comment field of run # 8967: "changed FS trigger to be RC.TD1.H1.. no INL only RC". I'm waiting for a feedback from Flemming to understand the problem. >Just to be on the safe side, this is then the code I'd be using (same for >T4 and T5...): > > Int_t CalibRunNo = 7634; > Don't use 7634. > > BrDCTrackingModule* t3 = new BrDCTrackingModule("T3", "T3", kFALSE); > t3->UseMySql(); > t3->SetMode(1); > t3->SetAssociatedHitsMode(kTRUE); > >t3->SetCalibFile(Form("/brahms/u/ufstasze/brahms/brahms_app/ps_app/dc/calib/calpar/T3CalibRun%d.dat", >CalibRunNo)); > >t3->SetOffsetFile(Form("/brahms/u/ufstasze/brahms/brahms_app/ps_app/dc/calib/calpar/T3OffsetRun%d.dat", >CalibRunNo)); > t3->SetMinWidth(16); > t3->SetHitNumberLimit(10, 1500); > t3->SetVerbose(50); > > // T3 > BrDcRdoModule* t3Rdo = new BrDcRdoModule("T3", "T3"); > >t3Rdo->SetCalibFile(Form("/brahms/u/ufstasze/brahms/brahms_app/ps_app/dc/calib/calpar/T3CalibRun%d.dat", > CalibRunNo)); > >t3Rdo->SetOffsetFile(Form("/brahms/u/ufstasze/brahms/brahms_app/ps_app/dc/calib/calpar/T3OffsetRun%d.dat", > CalibRunNo)); > mainModule->AddModule(t3Rdo); > > >For T5, I'd set the following change: >t5->SetViewCombinerParams(1,1,2,0,0); >t5->SetHitNumberLimit(6, 1500); >(by looking at the code most recently used by Ian...) and maybe drop the >T4 Rdo module? > >Please let me know if the above is somwhow wrong, or if there's anything >else I should know before launching this reco. > > To get the right local dc tracking setup just refer to ProductionReduction.C on ~bramreco/reduce. >Ping :-) > >-- >Bjorn H.
