cf6522d1 1//Created by Christine Nattrass, Rebecca Scott, Irakli Martashvili
020abff0 2//University of Tennessee at Knoxville
cf6522d1 3// This is a container class for the correction factors for the hadronic
4// component of transverse energy
5// It is filled by the output of AliAnalysisTaskHadEt from spinning over Monte
6// Carlo data (using AliAnalysisHadEtMonteCarlo)
7//It is used by AliAnalysisTaskHadEt while spinning over reconstructed data
8// (using AliAnalysisHadEtReconstructed)
