Contributions of different approximation orders to l = 1,m = 0 mode frequencies: σ2eigen (σ3eigen) represent the implicit second (third respectively) order contribution to the eigenfrequency; σ2T and σ3T denote second and third order frequency corrections due to the Coriolis acceleration; σ2D and σ3D represent 2nd and 3rd order frequency corrections due to the centrifugal distorsion; σ3C comes from the coupling of the distorsion and Coriolis effects. The contributions are plotted as a function of the radial order n for an 8.5 M⊙ ZAMS model rotating uniformly at 15% Ωk, i.e. around 95 km s-1 (see stellar parameters in Table 1). The frequencies are scaled by , so that σ = ω/Ωk. We use a negative radial order n for gravity modes and a positive one for acoustic modes.
