Notes. The first 22 cases were computed considering Mimas to be in hydrostatic equilibrium, while the 23rd is based on the observed shape. We give only one possibility for the shape model because the ratios of the moments of inertia A/C and B/C remain constant, so the rotational response of Mimas is the same for any interior model based on the shape.
