1 | PHOS QA class for using in PbPb runs in the PWGPP QA train. | |
2 | ||
3 | The main objective is to provide a user with an input for pi0 mass, | |
4 | width and number-of-pi0-per-event trend plots in PbPb | |
5 | runs. Unfortunately, large combinatorial background prevents from the | |
6 | direct using of CaloCellQA framework for this, so the event mixing | |
7 | technique is essential. | |
8 | ||
9 | This class provides the standard set of 2D-histograms: invariant mass | |
10 | of two clusters in PHOS vs their pT both for "real" and "mixed" events | |
11 | for each of the three PHOS modules in centrality bins 0-20% and | |
12 | 20-100% (cen0 and cen1 in the histogram names, resp). Only clusters | |
13 | with energy > 0.3 GeV and number of cells >2 are accepted. | |
14 | ||
15 | "Mixed" histograms are identified by "Mi" in their names. | |
16 | ||
17 | Requires no configuration. |
