18 | // Class to calculate calibration parameters from beam tests etc. | |
19 | // First pass - one should calcuate pedestals, in the second pass - gains. | |
20 | // | |
21 | // To calculate pedestals we scan pedestals events and fill histos for each | |
22 | // channel. Then in each histo we find maximum and fit it with Gaussian in the | |
23 | // visinity of the maximum. Extracted mean and width of distribution are put into | |
24 | // resulting histogram which cheks results for 'reasonability'. | |
25 | // | |
26 | // To evaluate gains: scans beam events and calculate gain in the cristall with | |
27 | // maximal energy deposition, assuming, that 90% of energy deposited in it. | |
28 | // For each channel separate histogramm is filled. When scan is finished, | |
29 | // these histograms are fitted with Gaussian and finds mean and width, which | |
30 | // are put in final histogram. Finaly gains are checked for deviation from mean. | |
31 | ||
32 | // Finally fills database. | |
33 | // | |
34 | // Use Case: | |
35 | // AliPHOSCalibrator * c = new AliPHOSCalibrator("path/galice.root") ; | |
36 | // c->AddRun("path2/galice.root") ; | |
37 | // c->ScanPedestals(); | |
38 | // c->CalculatePedestals(); | |
39 | // c->WritePedestals(); | |
40 | // c->ScanGains() ; | |
