You cannot process runs with different // filling schemes if this option is set. If you want to disable this, // use: // fPhysicsSelection->SetUseBXNumbers(0); // // // If you are analizing muons and you want to keep the muon triggers // besides the CINT1B you can set: // fPhysicsSelection->SetUseMuonTriggers(); // // // To compute the Background automatically using the control triggers // use: // fPhysicsSelection->SetComputeBG(); // this will show the value of the Beam Gas, accidentals and good // events as additional rows in the statistic tables, but it will NOT // subtract the background automatically. // This option will only work for runs taken with the CINT1 // suite. This options enables automatically also the usage of BX // numbers. You can only process one run at a time if you require this // options, because it uses the bunch intensity estimated run by run. // // The BG will usually be more important in the so-called "bin 0": the // class can also compute the statistics table for events in this // bin. Since the definition of bin 0 may in general change from // analysis to analysis, the user needs to provide a callback // implementing the definition of bin zero. The callback should be // implemented as a method in the analysis task and should override // the IsEventInBinZero method of AliAnalysisTaskSE, and should thus // have the the following prototype: // Bool_t IsEventInBinZero(); // It should return true if the event is in the bin 0 and it is set by // passing to the physics selection the NAME of the task where the // callback is implemented: // fPhysicsSelection->SetBin0Callback("MyTask"). // // // Usually the class selects the trigger scheme by itself depending on the run number. // Nevertheless, you can do that manually by calling AddCollisionTriggerClass() and AddBGTriggerClass() // Example: // To define the class CINT1B-ABCE-NOPF-ALL as collision trigger (those will be accepted as // collision candidates when they pass the selection): // AddCollisionTriggerClass("+CINT1B-ABCE-NOPF-ALL #769 #3119"); // To select on bunch crossing IDs in addition, use: // AddCollisionTriggerClass("+CINT1B-ABCE-NOPF-ALL #769 #3119"); // To define the class CINT1A-ABCE-NOPF-ALL as a background trigger (those will only be counted // for the control histograms): // AddBGTriggerClass("+CINT1A-ABCE-NOPF-ALL"); // You can also specify more than one trigger class in a string or you can require that some are *not* // present. The following line would require CSMBA-ABCE-NOPF-ALL, but CSMBB-ABCE-NOPF-ALL is not allowed // to be present: // AddBGTriggerClass("+CSMBA-ABCE-NOPF-ALL -CSMBB-ABCE-NOPF-ALL"); // // Origin: Jan Fiete Grosse-Oetringhaus, CERN // Michele Floris, CERN //------------------------------------------------------------------------- #include #include #include #include #include #include #include #include #include #include #include #include #include "AliAnalysisManager.h" ClassImp(AliPhysicsSelection) AliPhysicsSelection::AliPhysicsSelection() : AliAnalysisCuts("AliPhysicsSelection", "AliPhysicsSelection"), fCurrentRun(-1), fMC(kFALSE), fCollTrigClasses(), fBGTrigClasses(), fTriggerAnalysis(), fBackgroundIdentification(0), fHistBunchCrossing(0), fHistTriggerPattern(0), fSkipTriggerClassSelection(0), fUsingCustomClasses(0), fSkipV0(0), fBIFactorA(1), fBIFactorC(1), fComputeBG(0), fUseBXNumbers(1), fUseMuonTriggers(0), fFillingScheme(""), fBin0CallBack(""), fBin0CallBackPointer(0) { // constructor fCollTrigClasses.SetOwner(1); fBGTrigClasses.SetOwner(1); fTriggerAnalysis.SetOwner(1); fHistStatistics[0] = 0; fHistStatistics[1] = 0; AliLog::SetClassDebugLevel("AliPhysicsSelection", AliLog::kWarning); } AliPhysicsSelection::~AliPhysicsSelection() { // destructor fCollTrigClasses.Delete(); fBGTrigClasses.Delete(); fTriggerAnalysis.Delete(); if (fHistStatistics[0]) { delete fHistStatistics[0]; fHistStatistics[0] = 0; } if (fHistStatistics[1]) { delete fHistStatistics[1]; fHistStatistics[1] = 0; } if (fHistBunchCrossing) { delete fHistBunchCrossing; fHistBunchCrossing = 0; } if (fHistTriggerPattern) { delete fHistTriggerPattern; fHistTriggerPattern = 0; } } Bool_t AliPhysicsSelection::CheckTriggerClass(const AliESDEvent* aEsd, const char* trigger) const { // checks if the given trigger class(es) are found for the current event // format of trigger: +TRIGGER1 -TRIGGER2 // requires TRIGGER1 and rejects TRIGGER2 Bool_t foundBCRequirement = kFALSE; Bool_t foundCorrectBC = kFALSE; TString str(trigger); TObjArray* tokens = str.Tokenize(" "); for (Int_t i=0; i < tokens->GetEntries(); i++) { TString str2(((TObjString*) tokens->At(i))->String()); if (str2[0] == '+' || str2[0] == '-') { Bool_t flag = (str2[0] == '+'); str2.Remove(0, 1); if (flag && !aEsd->IsTriggerClassFired(str2)) { AliDebug(AliLog::kDebug, Form("Rejecting event because trigger class %s is not present", str2.Data())); delete tokens; return kFALSE; } if (!flag && aEsd->IsTriggerClassFired(str2)) { AliDebug(AliLog::kDebug, Form("Rejecting event because trigger class %s is present", str2.Data())); delete tokens; return kFALSE; } } else if (str2[0] == '#') { foundBCRequirement = kTRUE; str2.Remove(0, 1); Int_t bcNumber = str2.Atoi(); AliDebug(AliLog::kDebug, Form("Checking for bunch crossing number %d", bcNumber)); if (aEsd->GetBunchCrossNumber() == bcNumber) { foundCorrectBC = kTRUE; AliDebug(AliLog::kDebug, Form("Found correct bunch crossing %d", bcNumber)); } } else AliFatal(Form("Invalid trigger syntax: %s", trigger)); } delete tokens; if (foundBCRequirement && !foundCorrectBC) return kFALSE; return kTRUE; } Bool_t AliPhysicsSelection::IsCollisionCandidate(const AliESDEvent* aEsd) { // checks if the given event is a collision candidate if (fCurrentRun != aEsd->GetRunNumber()) if (!Initialize(aEsd->GetRunNumber())) AliFatal(Form("Could not initialize for run %d", aEsd->GetRunNumber())); const AliESDHeader* esdHeader = aEsd->GetHeader(); if (!esdHeader) { AliError("ESD Header could not be retrieved"); return kFALSE; } // check event type; should be PHYSICS = 7 for data and 0 for MC if (!fMC) { if (esdHeader->GetEventType() != 7) return kFALSE; } else { if (esdHeader->GetEventType() != 0) AliFatal(Form("Invalid event type for MC: %d", esdHeader->GetEventType())); } Bool_t accept = kFALSE; Int_t count = fCollTrigClasses.GetEntries() + fBGTrigClasses.GetEntries(); for (Int_t i=0; i < count; i++) { const char* triggerClass = 0; if (i < fCollTrigClasses.GetEntries()) triggerClass = ((TObjString*) fCollTrigClasses.At(i))->String(); else triggerClass = ((TObjString*) fBGTrigClasses.At(i - fCollTrigClasses.GetEntries()))->String(); AliDebug(AliLog::kDebug, Form("Processing trigger class %s", triggerClass)); AliTriggerAnalysis* triggerAnalysis = static_cast (fTriggerAnalysis.At(i)); triggerAnalysis->FillTriggerClasses(aEsd); if (CheckTriggerClass(aEsd, triggerClass)) { triggerAnalysis->FillHistograms(aEsd); Bool_t isBin0 = kFALSE; if (fBin0CallBack != "") { AliAnalysisManager *mgr = AliAnalysisManager::GetAnalysisManager(); if (!mgr) { AliError("Cannot get the analysis manager"); } else { isBin0 = ((AliAnalysisTaskSE*)mgr->GetTask(fBin0CallBack.Data()))->IsEventInBinZero(); } } else if (fBin0CallBackPointer) { isBin0 = (*fBin0CallBackPointer)(aEsd); } // hardware trigger (should only remove events for MC) // replay CINT1B hardware trigger // TODO this has to depend on the actual hardware trigger (and that depends on the run...)
