191. What do we calibrate.
20
21 Time dependence of gain and drift velocity in order to account for changes in: temperature, pressure, gas composition.
22
23 AliTPCcalibTime *calibTime = new AliTPCcalibTime("cosmicTime","cosmicTime",0, 1213.9e+06, 1213.96e+06, 0.04e+04, 0.04e+04);
24
252. How to interpret results
26
273. Simple example
28
29 a) determine the required time range:
30
31 AliXRDPROOFtoolkit tool;
32 TChain * chain = tool.MakeChain("pass2.txt","esdTree",0,6000);
33 chain->Draw("GetTimeStamp()")
34
35 b) analyse calibration object on Proof in calibration train
36
37 AliTPCcalibTime *calibTime = new AliTPCcalibTime("cosmicTime","cosmicTime", StartTimeStamp, EndTimeStamp, IntegrationTimeVdrift);
38
39 c) plot results
40 .x ~/NimStyle.C
41 gSystem->Load("libANALYSIS");
42 gSystem->Load("libTPCcalib");
43
44 TFile f("CalibObjectsTrain1.root");
45 AliTPCcalibTime *calib = (AliTPCcalibTime *)f->Get("calibTime");
46 calib->GetHistoDrift("all")->Projection(2,0)->Draw()
47 calib->GetFitDrift("all")->Draw("lp")
48
494. Analysis using debug streamers.
50
51 gSystem->AddIncludePath("-I$ALICE_ROOT/TPC/macros");
52 gROOT->LoadMacro("$ALICE_ROOT/TPC/macros/AliXRDPROOFtoolkit.cxx+")
53 AliXRDPROOFtoolkit tool;
54 TChain * chainTime = tool.MakeChainRandom("time.txt","trackInfo",0,10000);
55
56 AliXRDPROOFtoolkit::FilterList("timetpctpc.txt","* tpctpc",1)
57 AliXRDPROOFtoolkit::FilterList("timetoftpc.txt","* toftpc",1)
58 AliXRDPROOFtoolkit::FilterList("timeitstpc.txt","* itstpc",1)
59 AliXRDPROOFtoolkit::FilterList("timelaser.txt","* laserInfo",1)
60 TChain * chainTPCTPC = tool.MakeChainRandom("timetpctpc.txt.Good","tpctpc",0,10000);
61 TChain * chainTPCITS = tool.MakeChainRandom("timeitstpc.txt.Good","itstpc",0,10000);
62 TChain * chainTPCTOF = tool.MakeChainRandom("timetoftpc.txt.Good","toftpc",0,10000);
