19 | // Implementation version vImpacts of PHOS Manager class. | |
20 | // This class inherits from v1 and adds impacts storing. | |
21 | // Impacts stands for exact values of track coming to the detectors | |
22 | // EMC, CPV or PPSD. | |
23 | // Impacts are written to the same tree as hits are | |
24 | // but in separate branches. | |
