74235403 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.
c74c5f6c 22
23 AliTPCcalibTime *calibTime = new AliTPCcalibTime("cosmicTime","cosmicTime",0, 1213.9e+06, 1213.96e+06, 0.04e+04, 0.04e+04);
24
74235403 252. How to interpret results
26
273. Simple example
c74c5f6c 28
74235403 29 a) determine the required time range:
c74c5f6c 30
74235403 31 AliXRDPROOFtoolkit tool;
32 TChain * chain = tool.MakeChain("pass2.txt","esdTree",0,6000);
33 chain->Draw("GetTimeStamp()")
c74c5f6c 34
74235403 35 b) analyse calibration object on Proof in calibration train
c74c5f6c 36
74235403 37 AliTPCcalibTime *calibTime = new AliTPCcalibTime("cosmicTime","cosmicTime", StartTimeStamp, EndTimeStamp, IntegrationTimeVdrift);
c74c5f6c 38
74235403 39 c) plot results
40 .x ~/NimStyle.C
2be25cc9 41 gSystem->Load("libANALYSIS");
42 gSystem->Load("libTPCcalib");
c74c5f6c 43
dde68d36 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")
da6c0bc9 48
74235403 494. Analysis using debug streamers.
da6c0bc9 50
