Effect of the meridional flow (Eq. 24) on the m = 2 mode frequencies, ω. The surface latitudinal differential rotation is from Larson & Schou (2018). The black squares show the mode frequencies when the meridional flow is included and the red circles are for when it is not. The full symbols correspond to the symmetric modes, and the open symbols correspond to the antisymmetric modes. The Ekman number is fixed at E = 4 × 10⁻⁴ and all frequencies are expressed in the Carrington frame of reference. The eigenfunctions of the modes R, A₁, and P₁ are shown in Fig. C.5.
