Dear All,

I have made few more test after discussions with Stefano in order to check
where the high momenta tail is coming from: tracking code or Kalman
(as it was suggested by Gianluigi).

What i have done is to switch on native tracking by using in the pid level:

PndPidCorrelator* corr = new PndPidCorrelator();
corr->SetInputBranch("SttMvdGemTrack");
corr->SetInputIDBranch("SttMvdGemTrackID");
corr->SetDebugMode(kFALSE);
fRun->AddTask(corr);

One can see that the tail at high momenta (up to 15GeV/c) is present
also with native tracking. So it means it is not coming from genfit.

It would be nice that experts can cross check this problem in the code as well.
