Radiative and viscous diffusion time scales that depend on the distance from the central star for our standard disc model. To compute the time scales we used the density and temperature of the midplane at the beginning of the fully radiative simulations (when the disc is in the r − θ equilibrium between viscous heating and radiative transport/cooling). Libration time scales are stated for 20 and 30 MEarth planets.
