| 33 | | The density (in GeV/A) of pile-up contamination (rho) per event is computed within the {{{FastJetFinder}}} module if the following parameters are defined: |
| | 33 | For estimating pile-up contribution we use the well known fastjet area method, see for instance [http://arxiv.org/abs/0802.1188 arXiv:0802.1188], [http://arxiv.org/abs/0707.1378 arXiv:0707.1378]. |
| | 34 | First, the user must specify whether to calculate the area while clustering the jets within the {{{FastJetFinder}}} module . Several methods for the area calculation can also be specified (active area, passive area, Voronoi …) via the parameter {{{AreaAlgorithm}}}. By default this parameter is set to 0 (no area calculation): |
| | 35 | |
| | 36 | {{{ |
| | 37 | # area algorithm: 0 Do not compute area, 1 Active area explicit ghosts, 2 One ghost passive area, 3 Passive area, 4 Voronoi, 5 Active area |
| | 38 | set AreaAlgorithm 5 |
| | 39 | }}} |

| | 41 | Then the median density (in GeV/A) of pile-up contamination (rho) per event can computed by defining the following parameters are defined: |
