Frequency splittings (δν) calculated for mixed modes frequencies of a M_⋆ = 1.5 M_⊙, Z = 0.02, ν_max ≃ 172 μHz red giant, corresponding to (a) magnetic splitting, (b) the Coriolis effect, (c) the change from co-rotating to inertial frame, and (d) total frequency shifts. Red lines and points represent splittings for the m = 0 component. The blue and green lines represent the magnetic splitting for the m = 1 and m = −1 components respectively, that overlap on panel a. The grey dashed line represents the ζ function as defined by Goupil et al. (2013), the beige vertical line indicates the position of ν_max, and the grey vertical line the frequency of the ℓ = 1 g-dominated mode closest to ν_max, ν_{1, g, max}, with squares indicating the corresponding splitting values associated with the different orders m.
