Maire Nov2010, antonin.maire@ires.in2p3.fr // Modified for PbPb analysis: M. Nicassio Feb2011, maria.nicassio@ba.infn.it: // - physics selection moved to the runProof.C macro // - added centrality selection // - added new histograms // - modified binning of some histograms and containers // - flag to enable CF container usage // - protection in the destructor for CAF usage // - flag for acceptance cut in the MC part // - in the MC particle selection IsPhysicalPrimary added and number of particles taken as appropriate for HIJING // (however for cascades one gets the same if runs on Nprimaries in the stack and does not require IsPhysicalPrimary) // - number of tracklets from AOD also // - automatic settings for PID (July 2011) // - added possibility to select either injected cascades or HIJING cascades (May 2011) //----------------------------------------------------------------- #include #include "TList.h" #include "TFile.h" #include "TH1F.h" #include "TH2F.h" #include "TH3F.h" #include "TVector3.h" #include "TCanvas.h" #include "TParticle.h" #include "TMath.h" #include "AliLog.h" #include "AliHeader.h" #include "AliMCEvent.h" #include "AliStack.h" #include "AliMultiplicity.h" #include "AliInputEventHandler.h" #include "AliAnalysisManager.h" #include "AliCentrality.h" #include "AliCFContainer.h" #include "AliESDVZERO.h" #include "AliGenEventHeader.h" #include "AliGenCocktailEventHeader.h" #include "AliGenHijingEventHeader.h" #include "AliESDtrackCuts.h" #include "AliPIDResponse.h" // #include "AliV0vertexer.h" // #include "AliCascadeVertexer.h" #include "AliESDEvent.h" #include "AliESDcascade.h" #include "AliAODEvent.h" #include "AliAnalysisTaskCheckPerformanceCascadePbPb.h" ClassImp(AliAnalysisTaskCheckPerformanceCascadePbPb) //_____Dummy constructor________________________________________________________________ AliAnalysisTaskCheckPerformanceCascadePbPb::AliAnalysisTaskCheckPerformanceCascadePbPb() : AliAnalysisTaskSE(), // <- take care to AliAnalysisTask( empty ) fDebugCascade(0), fAnalysisType("ESD"), fCollidingSystems(0), fESDtrackCuts(0), /*fPaveTextBookKeeping(0),*/ fPIDResponse (0), fkRerunV0CascVertexers (0), fkQualityCutZprimVtxPos (kTRUE), fkRejectEventPileUp (kTRUE), fkQualityCutNoTPConlyPrimVtx (kTRUE), fkQualityCutTPCrefit (kTRUE), fkQualityCut80TPCcls (kTRUE), fkIsDataRecoWith1PadTPCCluster (kTRUE), fkExtraSelections (0), fUseCFCont (0), fCentrLowLim(0), fCentrUpLim(0), fCentrEstimator(0), fVtxRange (0), fApplyAccCut (0), // -
