9// Class for trigger analysis.
59264fa6 10// Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells
11// ordered fNTRUPhi x fNTRUZ. The algorithm searches all possible
12// 4x4 crystal combinations per each TRU, adding the digits amplitude and
13// finding the maximum. Maximums are transformed in adc time samples.
14// Each time bin is compared to the trigger threshold until it is larger
15// and then, triggers are set. Thresholds need to be fixed.
16// Last 2 modules are half size in Phi, I considered that the number
17// of TRU is maintained for the last modules but final decision has not
18// been taken. If different, then this must to be changed.
f0377b23 19// Usage:
20//
21// //Inside the event loop
22// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
59264fa6 23// tr->SetL0Threshold(100);
f0377b23 24// tr->SetL1JetLowPtThreshold(1000);
25// tr->SetL1JetMediumPtThreshold(10000);
26// tr->SetL1JetHighPtThreshold(20000);
27// tr->Trigger(); //Execute Trigger
28// tr->Print(""); //Print results
