+/// Shortcut to the ordinary tracking for tracking detectors.
+///
+/// The fast simulation model describes what should be done instead of a
+/// normal tracking. Instead of the ordinary tracking, a particle momentum
+/// at the entrance of the tracking detector is smeared 
+/// (by Par02Smearer::SmearMomentum()) and the particle is placed at the
+/// tracking detector exit, at the place it would reach without the change
+/// of its momentum. Based on G4 
+/// examples/extended/parametrisations/Par01/include/Par01EMShowerModel.hh .
