Hi Ralf,
I have added a ideal reconstruction macro under pandaroot/macro/run/recoideal_complete.C

I put there:

 PndSttMvdGemTrackingIdeal* trackStt = new PndSttMvdGemTrackingIdeal();
  trackStt->SetRelativeMomentumSmearing(0.05);
  trackStt->SetVertexSmearing(0.05, 0.05, 0.05);
  trackStt->SetTrackingEfficiency(1.);
  trackStt->SetTrackOutput("SttMvdGemIdealTrack");
  fRun->AddTask(trackStt);


What I find strange is that if I run muons (13) at 1 GeV, with a momentum smearing of 5%, once I plot:

cbmsim.Draw("-1./SttMvdGemIdealTrack.fTrackParamLast.fQp>>aa(200,-1.5,0.5)","SttMvdGemIdealTrack.fRefIndex==0")


I obtain a width of 37 MeV instead of 50. Vertices seem fine.

Could you please check also in your case?
The second thing I found is that half of the track are failing with the kalman, which sounds a bit strange. But this I could check more deeply later.
