Dear all,
I have realized that in some cases (about 3% of the total number of tracks) the charge of the track is different if got from TrackParamFirst or TrackParamLast of LheGenTrack. How is it possible?

Another thing I have noticed is that the charge of the same track is different if obtained from LheTrack (usually equal to the MC charge) or from LheGenTrack. Rolling Eyes
Is there a point, in the Kalman filter, where the charge is set again? Do you have any idea about what is going on?

Thank you in advance.
Susanna
