2 | // *** Class AliRsnPairNtuple *** | |
3 | // | |
4 | // "Core" method for defining the work on a pari of particles. | |
5 | // For one analysis, one must setup one of this for each pair he wants to analyze, | |
6 | // adding to it all analysis which he desires to do. | |
7 | // Here he defines the cuts, and the particle types and charges, and can add | |
8 | // functions which do different operations on the same pair, and some binning | |
9 | // with respect to some kinematic variables (eta, momentum) | |
10 | // | |
