9// Class for trigger analysis.
10//
11// -- Author: Gustavo Conesa & Yves Schutz (IFIC, SUBATECH, CERN)
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.
