Radial rotation profiles of the MS_110 model 2 × 10⁴ s after the explosion. R_star is the equatorial surface radius and v_e is the equatorial rotational velocity. M_r, J_r, I_r and ω_r are the total bound mass, the total angular momentum, the angular velocity and the moment of inertia of all bound particles interior to the corresponding cylindrical surface r. v_r is the circular velocity at distance r from the rotation axis. ω_c is the angular velocity on the rotation axes (z-axis).
