22 | // 1. Before using this componenent the magnetic filed has to be set properly // | |
1c1a1176 | 23 | // 2. The systematic effects - unlinearities has to be understood |

26 | // the alignment is just effective alignment. Not second order corrction | |

58 | // 1. Tracklet - StreamLevel >1 | |
59 | // - Dump all information about tracklet match from sector1 to sector 2 | |
60 | // - Default histogram residulas created in parallel | |
61 | // - Check this streamer in case of suspicious content of these histograms | |
62 | // 2. Track - StreamLevel>5 | |
63 | // - For debugging of the edge effects | |
64 | // - All information - extrapolation inside of one sectors | |
