10 | // Class for trigger analysis. | |
59264fa6 | 11 | // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28 |
12 | // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible | |
13 | // 4x4 crystal combinations per each TRU, adding the digits amplitude and | |
14 | // finding the maximum. Maximums are transformed in ADC time samples. | |
15 | // Each time bin is compared to the trigger threshold until it is larger | |
16 | // and then, triggers are set. Thresholds need to be fixed. | |
bb38a8fc | 17 | // Usage: |

19 | // //Inside the event loop | |

24 | // tr->Trigger(); //Execute Trigger | |
