7984e5f7 | 3 | // Class to do the sharing correction. That is, a filter that merges |
4 | // adjacent strip signals presumably originating from a single particle | |
5 | // that impinges on the detector in such a way that it deposite energy | |
6 | // into two or more strips. | |
7 | // | |
8 | // Input: | |
9 | // - AliESDFMD object - from reconstruction | |
10 | // | |
11 | // Output: | |
12 | // - AliESDFMD object - copy of input, but with signals merged | |
13 | // | |
14 | // Corrections used: | |
15 | // - AliFMDCorrELossFit | |
16 | // | |
17 | // Histograms: | |
18 | // - For each ring (FMD1i, FMD2i, FMD2o, FMD3i, FMD3o) the distribution of | |
19 | // signals before and after the filter. | |
20 | // - For each ring (see above), an array of distributions of number of | |
21 | // hit strips for each vertex bin (if enabled - see Init method) | |
22 | // | |
