-/* Macro to produce trigger single muon efficiency versus pt plots for the
- 3 pt cuts. Results are compared to the reference (red curves).
- To be used with (at least) 10000 events as follows
- AliGenBox * gener = new AliGenBox(1);
- gener->SetPtRange(0.,10.);
- gener->SetPhiRange(0., 360.);
- gener->SetThetaRange(171.000,178.001);
- gener->SetPart(13); // or -13
- gener->SetOrigin(0.,0., 0.);
- gener->SetSigma(0.0, 0.0, 0.0);
