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 384 cells
13// ordered fNTRUPhi x fNTRUEta 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. It is found is maximum is isolated.
16// Maxima are transformed in adc time samples. Each time bin is compared to the
17// trigger threshold until it is larger and then, triggers are set.
18// Thresholds need to be fixed.
19// Last 2 modules are half size in Phi, I considered that the number
20// of TRU is maintained for the last modules but final decision has not
21// been taken. If different, then this must to be changed.
22// Usage:
23//
24// //Inside the event loop
25// AliEMCALTrigger *tr = new AliEMCALTrigger();//Init Trigger
26// tr->SetL0Threshold(100);
27// tr->SetL1GammaLowPtThreshold(1000);
28// tr->SetL1GammaMediumPtThreshold(10000);
29// tr->SetL1GammaHighPtThreshold(20000);
30// ....
31// tr->Trigger(); //Execute Trigger
32// tr->Print(""); //Print data members after calculation.

37// One TRU card receives 96 analogue sums from 12 FEE cards.
38// One sum is correcponding output from on module.
39// This patch has size 12x8 modules (24x16 modules).
40// Each SM has 3 TRU cards.
