Angular velocity profiles 〈Ω〉 ≡ 〈uϕ〉/〈ut〉 in Kerr–Schild coordinates in units of deg/GM/c3. The solid line plots the time-average value, and the shaded region plots one standard deviation. The dotted black line is the Keplerian fit ﹩{{\rm{\Omega }}}_{K}={({r}^{3/2}+a)}^{-1}﹩ for a* = +0.94. The MAD rotational profiles are sub-Keplerian and have a significantly greater spread as compared to the SANE models. The SANE angular velocity agrees with the Keplerian expectation.
