5 | // Class to study systematic shifts in pt and charge/pt respectively.Furthermore a comparison between | |
6 | // ESD and TPC track momenta is included. | |
4060dd2d | 7 | // Track cuts and a user defined shift in charge/pt can be switched on and off by user. |

9 | // Analysis with class AliPerfAnalyzeInvPt via AliPerformancePtCalib::Analyse(). : | |
10 | // Projection of charge/pt vs theta and vs phi resp. Histograms will be fitted with either | |
11 | // polynomial or gaussian fit function to extract minimum position of 1/pt. | |
12 | // Fit options and theta, phi bins can be set by user. | |
13 | // Attention: use the Set* functions of AliPerformancePtCalib when running AliPerformancePtCalib::Analyse(). | |
