Evolution of inclination of 5 M_Jup and 10 M_Jup planets with an initial inclination of i₀ = 40.0° (top) and i₀ = 75.0° (bottom) in circular orbits. The simulations have been restarted with a moving planet after the disc was evolved for a fixed planet for 400 planetary orbits. The time index has been reset to zero and the lines correspond to the expected damping rates from Fig. 5.
