3 | // PID performance checker of the TRD | |
4 | // | |
5 | // Performs checks of ESD information for TRD-PID and recalculate PID based on OCDB information | |
6 | // Also provides performance plots on detector based on the PID information - for the moment only | |
7 | // MC source is used but V0 is also possible. Here is a list of detector performance checks | |
8 | // - Integrated dE/dx per chamber | |
9 | // - <PH> as function of time bin and local radial position | |
10 | // - number of clusters/tracklet | |
11 | // - number of tracklets/track | |
