class AliRsnTOFT0maker: public TObject


This class contains the basic functions for the time zero
evaluation with TOF detector informations.
Use case in an analysis task:

Create the object in the task constructor (fTOFmakerANA is a private var)
fTOFmakerANA = new AliRsnTOFT0maker();
fTOFmakerANA->SetTimeResolution(115.0e-12); // if you want set the TOF res
115 ps is the TOF default resolution value

Use the RemakePID method in the task::Exec
Double_t* calcolot0;
calcolot0=fTOFmakerANA->RemakePID(fESD);
calcolot0[0] = calculated event time
calcolot0[1] = event time time resolution
calcolot0[2] = average event time for the current fill

Let consider that:
- the PIF is automatically recalculated with the event time subtrction
