19 // Class for trigger analysis.
20 // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
21 // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
22 // 2x2 and nxn (n multiple of 2) crystal combinations per each TRU, adding the
23 // digits amplitude and finding the maximum. If found, look if it is isolated.
24 // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
25 // threshold until it is larger and then, triggers are set. Thresholds need to be fixed.
28 // //Inside the event loop
