Only for larger times, greather than t ≈ 10000, we have seen that the amplitude of those oscillations decreases, while the center of the kink begins to move, a phenomenon that it is probably due to the accumulation of numerical errors and the corresponding excitation of linear radiation modes, or to higher order effects coupling the internal and the translation mode through discreteness.
