Irradiated run. The Reynolds stress was averaged over 41 time steps, from orbit 1000 to 5000 each step 100 orbits apart, calculated with different averaging methods. For “mean time” the mean u_φ was calculated through averaging over 40 time steps. For “Kepler” the velocity was calculated by subtracting the Kepler velocity and for the last one u_φ is calculated analytically by using the equilibrium Eq. (11). Spatial averages are taken from 4 AU to 10 AU.
