6 | // These can be used to extract charged particles multiplcicity from the ITS. |
7 | // |
8 | // A tracklet consist of two ITS clusters, one in the first pixel |
9 | // layer and one in the second. The clusters are associates if the |
10 | // differencies in Phi (azimuth) and Zeta (longitudinal) are inside |
11 | // a fiducial volume. In case of multiple candidates it is selected the |
12 | // candidate with minimum distance in Phi. |
13 | // The parameter AssociationChoice allows to control if two clusters |
14 | // in layer 2 can be associated to the same cluster in layer 1 or not. |
