19// Class for trigger analysis.
0964c2e9 20// Digits are grouped in TRU's (Trigger Units). A TRU consists of 384
21// cells ordered fNTRUPhi x fNTRUEta. The algorithm searches all possible 2x2
22// and nxn (n is a multiple of 2) cell combinations per each TRU, adding the
23// digits amplitude and finding the maximum. If found, look if it is isolated.
24// Maxima are transformed in ADC time samples. Each time bin is compared to the trigger
25// threshold until it is larger and then, triggers are set. Thresholds need to be fixed.
0b2ec9f7 26// Thresholds need to be fixed. Last 2 modules are half size in Phi, I considered
27// that the number of TRU is maintained for the last modules but decision not taken.
28// If different, then this must be changed.
f0377b23 29// Usage:
30//
31// //Inside the event loop
32// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
0b2ec9f7 33// tr->SetL0Threshold(100); //Arbitrary threshold values
f0377b23 34// tr->SetL1JetLowPtThreshold(1000);
35// tr->SetL1JetMediumPtThreshold(10000);
36// tr->SetL1JetHighPtThreshold(20000);
0964c2e9 37// ...
f0377b23 38// tr->Trigger(); //Execute Trigger
39// tr->Print(""); //Print results
