2 // Description:
3 // Class PndEmcClusterCalibrator
4 // Do an energy and position corrections for EMC cluster
5 // PndEmcClusterCalibrator is a factory which call specific method depending on the input parameter "method"
6 // method=1 - PndEmcClusterHistCalibrator is called, which perform correction from the interpolation on 2-dimensional histogram on (Energy, theta)
7 // method=2 - PndEmcClusterSimpleCalibrator is called, where energy correction is parametrised as a function of (Energy, theta)
8 // PndEmcAbsClusterCalibrator - abstract interface class
9 //
10 // Versions of the correction:
11 // 1 - "emc_module12.dat","emc_module3_2011_new.root","emc_module4_StraightGeo24.4.root","emc_module5_fsc.root" (+ full PANDA geometry) TGeant3

15 // PndEmcClusterHistCalibrator class is based on code PndEmcMakeCorr.cxx
16 // (A. Biegun, M. Babai)
17 // PndEmcClusterSimpleCalibrator class is based on EmcPhotonSimpleCalib class in Babar framework (Jan Zhong)
