Hi,
for each event, I do the following:
    for (Int_t k = 0; k < kalfit->GetEntriesFast(); k++) {
       kalTrack = (PndTrack*) kalfit->At(k);
       if (!kalTrack) continue;
       if (kalTrack->GetFlag() < 0) continue;

where kalfit is the TClonesArray of PndTracks produced by the Kalman:
      TClonesArray *kalfit = new TClonesArray("PndTrack");
      reco->SetBranchAddress("SttMvdGenTrack", &kalfit);

Then, if the track is a primary track (I check the MCTrackId of the corresponding TrackCand), I fill the histogram of the momentum distribution:
     hgen->Fill(kalTrack->GetParamFirst().GetMomentum().Mag());


Susanna
