+// Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells
+// ordered fNTRUPhi x fNTRUEta matrix. The algorithm searches all possible
+// 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the
+// digits amplitude and finding the maximum. It is found is maximum is isolated.
+// Maxima are transformed in adc time samples. Each time bin is compared to the
+// trigger threshold until it is larger and then, triggers are set.
+// Thresholds need to be fixed.
+// Last 2 modules are half size in Phi, I considered that the number
+// of TRU is maintained for the last modules but final decision has not
+// been taken. If different, then this must to be changed.
// Usage:
//
// //Inside the event loop
// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
-// tr->SetL0MBPbPbThreshold(500);
-// tr->SetL0MBppThreshold(100);
-// tr->SetL1JetLowPtThreshold(1000);
-// tr->SetL1JetMediumPtThreshold(10000);
-// tr->SetL1JetHighPtThreshold(20000);
-// tr->Trigger(); //Execute Trigger
-// tr->Print(""); //Print results
-// //are printed
