That means: The absolute value of the charge is fixed, its sign can change.

Then you have a found track with a charge sign as input to the Kalman and AFTER the Kalman fit you can have that the charge has changed sign, right?

Since the Kalman changes the sign at runtime, could it happen that the charge associated to the last hit (last params I mean) has opposite sign with respect to the one of the first hit?
Cheers,
Lia.
