Scatter plots for the high gridsize, peak , decay stage, t = 30 gyration periods. The n = 1 resonance is dominant, since the energy of the peaked wave mode remained at the parallel axis. Nevertheless, a small structure at μ₀ = 0.7 indicates the n = 2 resonance. The interactions with the left-handed circular polarised modes vanished after the driven stage and are not visible during the decay anymore.
