Hi Sebastian,
are you using the GeaneTrackRep::extrapolate(const DetPlane& pl, TMatrixT<double>& statePred, TMatrixT<double>& covPred, TMatrixT<double>& jacobian)) function? Because in that function I see that when backprop is true you call _geane->setBackProp() which sets fPropOption="BLE" but in that case GEANE would make the back-propagation to a specific tracklength ("L" option), while what we want here is to back-propagate to a plane: so in this case it should be fPropOption="BPE".

Hope this helps,
Lia.
