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 |

60 | // - Default histogram residulas created in parallel | |

62 | // 2. Track - StreamLevel>5 | |
63 | // - For debugging of the edge effects | |
