Profiles of MHD invariants along magnetic-field line anchored at R = 2.0 for each simulation at t = 1000. The quantities shown are the mass-loading parameter, κ; the normalized angular velocity of the magnetic surface, ω_*; the magnetic lever arm, λ; and the normalized total specific energy, e. The shaded area indicates the resistive MHD region, while the dashed vertical lines mark the positions of the SM, Alfvénic, and FM critical surfaces.
