+// Added a temporary fix to FindRefTrack to be able to handle reconstructed tracks
+// generated from ESD muon track information. The problem is that the ESD data at
+// the moment only contains the first hit on chamber 1. Hopefully in the near future
+// this will be fixed and all hit information will be available.
