48 | // The AliTPCCalibKr class description (TPC Kr calibration).\r | |
49 | //\r | |
50 | //\r | |
51 | // The AliTPCCalibKr keeps the array of TH3F histograms (TPC_max_padraw,TPC_max_pad,TPC_ADC_cluster),\r | |
52 | // its data memebers and is filled by AliTPCCalibKrTask under conditions (Accept()). \r | |
53 | // \r | |
54 | // The ouput TH3F histograms are later used to determine the calibration parameters of TPC chambers.\r | |
55 | // These calculations are done by using AliTPCCalibKr::Analyse() function. The ouput calibration \r | |
56 | // parameters (details in AliTPCCalibKr::Analyse()) are stored in the calibKr.root file for each TPC pad.\r | |
57 | // In addition the debugCalibKr.root file with debug information is created.\r | |
58 | //\r | |
59 | \r | |
60 | /*\r | |
61 | \r | |
62 | // Usage example:\r | |
63 | //\r | |
64 | \r | |
65 | // 1. Analyse output histograms:\r | |
66 | TFile f("outHistFile.root");\r | |
67 | AliTPCCalibKr *obj = (AliTPCCalibKr*) cOutput.FindObject("AliTPCCalibKr")\r | |

71 | TFile f("calibKr.root");\r | |
72 | spectrMean->GetCalROC(70)->GetValue(40,40);\r | |
