19Basic calibration and QA class for the PID of the TPC based on dEdx.
20
21The corrections which are done on the cluster level (angle,drift time etc.) are here checked by plotting the dE/dx for selected tracks as a function of these variables. In addition the Bethe-Bloch-Parameterisation is fitted to the distribution and the corresponding parameters are being extracted.
22
231.a) Fast equalization for different gain in pad regions:
24
25TFile f("CalibObjects.root")
26AliTPCcalibPID *cal = f->Get("TPCCalib")->FindObject("calibPID")
27
37fb53c1 28cal->GetHistRatioMaxTot()->Projection(0)->Fit("gaus")
29cal->GetHistRatioTracklet()->Projection(0)->Fit("gaus")
401ad2f1 30
311.b) Update OCDB:
32.x $ALICE_ROOT/TPC/macros/ConfigOCDB.C
33AliTPCClusterParam * parcl = AliTPCcalibDB::Instance()->GetClusterParam();
37fb53c1 34*parcl->fQpadMnorm)[ipad] = oldvalue*corrFactor
401ad2f1 35
36Int_t runNumber = 0;
37AliCDBMetaData *metaData= new AliCDBMetaData();
38metaData->SetObjectClassName("AliTPCClusterParam");
39metaData->SetResponsible("Alexander Kalweit");
40metaData->SetBeamPeriod(1);
41metaData->SetAliRootVersion("05-23-02");
42metaData->SetComment("October runs calibration");
43AliCDBId id1("TPC/Calib/ClusterParam", runNumber, AliCDBRunRange::Infinity());
44gStorage = AliCDBManager::Instance()->GetStorage("local://$ALICE_ROOT/OCDB");
45gStorage->Put(parcl, id1, metaData);
46
47
482.) Checks should be done with particles on the Fermi-Plateau and whoch leave a long track:
49
50cal->GetHistQmax()->GetAxis(6)->SetRangeUser(120,160)
51cal->GetHistQmax()->GetAxis(4)->SetRangeUser(20,50)
52
53variables to check:
54
55cal->GetHistQmax()->Projection(0,1)->Draw() z-dep.
56cal->GetHistQmax()->Projection(0,2)->Draw() snp-dep.
57cal->GetHistQmax()->Projection(0,3)->Draw() tgl-dep.
58
59
60
61 Comments to be written here:
62 1. What do we calibrate.
63 2. How to interpret results
64 3. Simple example
65 4. Analysis using debug streamers.
