-2. How to interpret results
-
-3. Simple example
-
- a) determine the required time range:
-
- AliXRDPROOFtoolkit tool;
- TChain * chain = tool.MakeChain("pass2.txt","esdTree",0,6000);
- chain->Draw("GetTimeStamp()")
-
- b) analyse calibration object on Proof in calibration train
-
- AliTPCcalibTime *calibTime = new AliTPCcalibTime("cosmicTime","cosmicTime", StartTimeStamp, EndTimeStamp, IntegrationTimeVdrift);
-
- c) plot results
- .x ~/NimStyle.C
- gSystem->Load("libANALYSIS");
- gSystem->Load("libTPCcalib");
-
- TFile f("CalibObjects.root");
- AliTPCcalibTime *cal = (AliTPCcalibTime *)f->Get("TPCCalib")->FindObject("calibTime");
- cal->GetHistoDrift("all")->Projection(2,0)->Draw()
- cal->GetFitDrift("all")->Draw("lp")
-
-4. Analysis using debug streamers.
-
- gSystem->AddIncludePath("-I$ALICE_ROOT/TPC/macros");
- gROOT->LoadMacro("$ALICE_ROOT/TPC/macros/AliXRDPROOFtoolkit.cxx+")
- AliXRDPROOFtoolkit tool;
- TChain * chainTime = tool.MakeChain("time.txt","timeInfo",0,10200);
- chainTime->Lookup();
