20// Class for trigger analysis.
21// Digits are grouped in TRU's (384 cells? ordered fNTRUPhi x fNTRUEta).
22// The algorithm searches all possible 4x4 cell combinations per each TRU,
23// adding the digits amplitude and finding the maximum. Maximums are compared
24// to triggers threshold and they are set. Thresholds need to be fixed.
59264fa6 25// Last 2 modules are half size in Phi, I considered that the number of TRU
26// is maintained for the last modules but decision not taken. If different,
27// then this must be changed.
f0377b23 28// Usage:
29//
30// //Inside the event loop
31// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
59264fa6 32// tr->SetL0Threshold(100);
f0377b23 33// tr->SetL1JetLowPtThreshold(1000);
34// tr->SetL1JetMediumPtThreshold(10000);
35// tr->SetL1JetHighPtThreshold(20000);
36// tr->Trigger(); //Execute Trigger
37// tr->Print(""); //Print results
