Notes. We consider one orbit for the 1:1 SOR (11.186 days) and two orbits (22.372 days) for the 3:2 SOR. Spin-up times for both simulations are considered (7400 days and 17 000 days for 1:1 and 3:2 SOR, respectively). The substellar point is always at 0◦ latitude and longitude for the 1:1 SOR. For the 3:2 SOR, the substellar longitude λSP(t) changes over time, as specified. All the angles are given in degrees.
