Rotational dependency of the diagonal α components. We show meridional profiles of α_rr (top row), α_θθ (second row), and α_ϕϕ (third row), and their rms values (bottom row), with α_rr (black lines), α_θθ (red), and α_ϕϕ (blue). As in Fig. 3 the values of the HD runs (Set H) are shown with a solid line and crosses, whereas the MHD runs (Set M) are shown with a dashed line with diamonds. All values are normalized by . The zero rotation run has been moved to Co = 10⁻⁴ to be visible in the lower panel.
