Same as Fig. 10, but for the Eddington–Sweet regime with parameters E = 10⁻⁵, P_r(N₀/Ω₀)² = 10⁻¹, and Re_c = 10⁻². The plain blue curve corresponds to the Boussinesq case (run 1.3 in Table 4), while the other curves are obtained by varying the density contrast between the inner and outer spheres in the same way as previously, but for runs 1.2–1.4 in Table 8 in the left panel, and for cases 1.1 and 1.3 in Table 8 in the middle and right panels.
