class AliPerformancePtCalib: public AliPerformanceObject

 Implementation of AliPerformancePtCalib class. It fills histograms with ESD or
 TPC track information to study charge/pt spectra.
 To analyse the output of AliPerformancePtCalib use AliPerfAnalyzeInvPt class:
 Projection of charge/pt vs theta and vs phi resp. histoprams will be fitted
 with either polynomial or gaussian fit function to extract minimum position of
 charge/pt.
 Fit options and theta, phi bins can be set by user.
 Attention: use the Set functions of AliPerformancePtCalib  when running
 AliPerformancePtCalib::Analyse()
 The result of the analysis (histograms/graphs) are stored in the folder which is
 a data member of AliPerformancePtCalib.
