12 : // Digits are grouped in TRU's (Trigger Units). A TRU consist of 16x28
13 : // crystals ordered fNTRUPhi x fNTRUZ matrix. The algorithm searches all possible
14 : // 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the
15 : // digits amplitude and finding the maximum. Iti is found is maximum is isolated.
16 : // Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
17 : // threshold until it is larger and then, triggers are set. Thresholds need to be fixed.
18 : // Usage:
19 : //
20 : // //Inside the event loop
21 : // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
22 : // tr->SetL0Threshold(100);
23 : // tr->SetL1JetLowPtThreshold(1000);
24 : // tr->SetL1JetMediumPtThreshold(10000);
25 : // tr->SetL1JetHighPtThreshold(20000);
26 : // ....
27 : // tr->Trigger(); //Execute Trigger
28 : // tr->Print(""); //Print data members after calculation.
