Differential rotation in the Eddington–Sweet linear regime for P_r(N₀/Ω₀)² = 10⁻¹ (top panel) and 10⁻² (bottom panel), the other two parameters E = 10⁻⁶ and Re_c = 10⁻² being identical (runs 1.4 and 2.2 in Table 4). The coloured contours are normalised to the rotation rate of the outer sphere Ω₀. Left column: differential rotation δΩ(r, θ)/Ω₀ rescaled by E (P_r(N₀/Ω₀)²R_o)⁻¹. Middle column: differential rotation obtained after subtracting the unstratified Taylor–Proudman solution given by Eq. (45) and rescaling by E (P_r(N₀/Ω₀)²R_o)⁻¹ (see Eq. (53)). Right column: ratio .
