Velocities projected on a streamline passing through (r = 6r₀,z = 5h) in run R10-M3-C2 (fiducial), averaged from 400T₀ to 500T₀, and normalized by the Keplerian velocity at the launching radius v_K0; flow velocity v (solid black), sound speed c_s (dashed orange), Alfvén velocity v_A (dashed green), slow magnetosonic speed v₋ (dashed blue) and fast magnetosonic speed v₊ (red dots).
