14 // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
15 // crystals ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
16 // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the
17 // digits amplitude and finding the maximum. Iti is found is maximum is isolated.
18 // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
19 // threshold until it is larger and then, triggers are set. Thresholds need to be fixed.
22 // //Inside the event loop
23 // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
24 // tr->SetL0Threshold(100);
25 // tr->SetL1JetLowPtThreshold(1000);
26 // tr->SetL1JetHighPtThreshold(20000);
28 // tr->Trigger(); //Execute Trigger
29 // tr->Print(""); //Print data members after calculation.
