10// Class for trigger analysis.
0964c2e9 11//
12// -- Author: Gustavo Conesa & Yves Schutz (IFIC, SUBATECH, CERN)
59264fa6 13// Digits are grouped in TRU's (Trigger Units). A TRU consist of 384 cells
0964c2e9 14// ordered fNTRUPhi x fNTRUEta matrix. The algorithm searches all possible
15// 2x2 and nxn (n multiple of 4) crystal combinations per each TRU, adding the
16// digits amplitude and finding the maximum. It is found is maximum is isolated.
17// Maxima are transformed in adc time samples. Each time bin is compared to the
18// trigger threshold until it is larger and then, triggers are set.
19// Thresholds need to be fixed.
59264fa6 20// Last 2 modules are half size in Phi, I considered that the number
21// of TRU is maintained for the last modules but final decision has not
22// been taken. If different, then this must to be changed.
f0377b23 23// Usage:
24//
25// //Inside the event loop
26// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
59264fa6 27// tr->SetL0Threshold(100);
f0377b23 28// tr->SetL1JetLowPtThreshold(1000);
29// tr->SetL1JetMediumPtThreshold(10000);
30// tr->SetL1JetHighPtThreshold(20000);
0964c2e9 31// ....
f0377b23 32// tr->Trigger(); //Execute Trigger
0964c2e9 33// tr->Print(""); //Print data members after calculation.
