Both the finder that is based on combined muon tracks as well as the finder based on single muon tracks work in the same way: A muon candidate consists of all calorimeter condensates which are hit by the muon track. If a candidate is found all candidate parameters are calculated at highest precision. For the finder based on combined muon tracks the trajectory fit is not redone because the muon chamber tracks are the best estimate for the trajectory. For the finder based on single muon tracks the offset vector is not refitted but only the direction of the trajectory.
