Hough functions (normalised to unity) in the non-magnetic (top) and magnetic (bottom) cases as a function of the horizontal coordinate x at different radii from the radiative-convective interface (dark blue) to the surface (orange) for m = −1, ν = 10, and Ω = 22.19 Ω_⊙ at B₀ = 10⁵ G using the 1.6 M_⊙γ Dor model at ZAMS. Solid lines correspond to gravity-like solutions (k = 0), and dotted lines correspond to Rossby-like solutions (k = −2).
