12 // Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells
13 // ordered fNTRUPhi x fNTRUEta 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. It is found is maximum is isolated.
16 // Maxima are transformed in adc time samples. Each time bin is compared to the
17 // trigger threshold until it is larger and then, triggers are set.
18 // Thresholds need to be fixed.
19 // Last 2 modules are half size in Phi, I considered that the number
20 // of TRU is maintained for the last modules but final decision has not
21 // been taken. If different, then this must to be changed.
24 // //Inside the event loop
25 // AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
26 // tr->SetL0Threshold(100);
27 // tr->SetL1JetLowPtThreshold(1000);
28 // tr->SetL1JetMediumPtThreshold(10000);
29 // tr->SetL1JetHighPtThreshold(20000);
31 // tr->Trigger(); //Execute Trigger
32 // tr->Print(""); //Print data members after calculation.
