51 | * Class produces physics histograms for PHOS. It takes a TClonesArray | |
52 | * of AliESDCalocluster as input and fills several histograms | |
53 | * | |
54 | * Histograms (1D): | |
55 | * - Total number of clusters per event | |
56 | * - Energy distribution of clusters | |
57 | * - Total energy in event | |
58 | * - Invariant mass of two clusters | |
59 | * - Number of cells in clusters | |
60 | * - Fraction of cells with energy deposit | |
61 | * | |
62 | * Histograms (2D): | |
63 | * - Number of cells in cluster vs cluster energy | |
64 | * - Number of clusters vs total energy | |
