- Adding sparse histograms to analysis

[u/mrichter/AliRoot.git] / T0 / AddTaskT0Calib.C

/*

 This macros setup the TPC calibration task AddTaskTPCCalib
 for Pass0.
 - the run number is required to config TPC OCDB
 
 The following calibration components are added to the AliTPCAnalysisTaskcalib task:
 1. AliTPCcalibCalib - redo reconstruction with current calibration
 2. AliTPCcalibTimeGain - TPC time dependent gain calibration
 3. AliTPCcalibTime - TPC time dependent drift time calibration
 4. AliTPCcalibLaser - laser track calibration
