| 18 | // This task is meant to explore the possibility of using a VZERO amplitude |
| 1b914674 |
19 | // based multiplicity estimator for proton-proton collisions. For this, two |
| 20 | // main operation methods for this task are foreseen: |
| af0d4791 |
21 | // |
| 1b914674 |
22 | // 1) (under development) it should act as an auxiliary task and provide a |
| 23 | // calibrated estimator |
| 24 | // |
| 25 | // 2) "Debug mode" which will also create a ROOT TTree object with event |
| 26 | // by event info potentially used for exploration / calibration. This |
| 27 | // includes the following info: |
| 28 | // |
| 29 | // --- All VZERO Amplitudes (saved as Float_t) |
| af0d4791 |
30 | // --- (optional) time for each channel |
| 1b914674 |
31 | // --- (optional) time width for each channel |
| 32 | // --- GetReferenceMultiplicity Estimator, |eta|<0.5 |
| 33 | // --- GetReferenceMultiplicity Estimator, |eta|<0.8 |
| af0d4791 |
34 | // --- (if MC) True Multiplicity, |eta|<0.5 |
| 35 | // --- (if MC) True Multiplicity, 2.8 < eta < 5.8 (VZEROA region) |
| 36 | // --- (if MC) True Multiplicity, -3.7 < eta <-1.7 (VZEROC region) |
| 37 | // --- Run Number |
