It provides functionality to limit the stepsize of an extrapolation in order not to exceed a specified maximum momentum loss. After propagation, the energy loss for the given length and (optionally) the noise matrix can be calculated. You have to set which energy-loss and noise mechanisms you want to use. At the moment, per default all energy loss and noise options are ON.
