Rotational dependency of the turbulent diffusion as the trace of β. We show meridional profiles of β_tr (top row) and the rms values of the diagonal component (bottom row), with β_rr (black lines), β_θθ (red), and β_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.
