4 | // This class is designed for the analysis of the hadronic component of | |
5 | // transverse energy. It is used by AliAnalysisTaskHadEt. | |
6 | // This gets information about the hadronic component of the transverse energy | |
7 | // from tracks reconstructed in an event | |
8 | // it has daughters, AliAnalysisHadEtMonteCarlo and | |
9 | // AliAnalysisHadEtReconstructed which loop over either Monte Carlo data or | |
10 | // real data to get Et | |
