| 7984e5f7 | 2 | // Class to do the sharing correction. That is, a filter that merges |
| 3 | // adjacent strip signals presumably originating from a single particle | |
| 4 | // that impinges on the detector in such a way that it deposite energy | |
| 5 | // into two or more strips. | |
| 6 | // | |
| 7 | // Input: | |
| 8 | // - AliESDFMD object - from reconstruction | |
| 9 | // | |
| 10 | // Output: | |
| 11 | // - AliESDFMD object - copy of input, but with signals merged | |
| 12 | // | |
| 13 | // Corrections used: | |
| 14 | // - AliFMDCorrELossFit | |
| 15 | // | |
| 16 | // Histograms: | |
| 17 | // - For each ring (FMD1i, FMD2i, FMD2o, FMD3i, FMD3o) the distribution of | |
| 18 | // signals before and after the filter. | |
| 19 | // - For each ring (see above), an array of distributions of number of | |
| 20 | // hit strips for each vertex bin (if enabled - see Init method) | |
