First-order perturbations to the p-mode frequency due to a g-mode oscillation assumed to be frozen over the observation period. Results are shown for g modes and p modes with harmonic degrees l_g = l_p = 2 and azimuthal orders m_g = m_p = 0. Left: frequency shift as a function of radial order for mode frequencies ν_p <  5 mHz and ν_g >  5.67 μHz. The range of modes studied by Fossat et al. (2017), Fossat & Schmider (2018), and Schunker et al. (2018) is inside the dashed rectangle, extending outwards of the plotted region at |n_g| > 200. Right: cuts through the results shown in the dashed region in the left panel for a selection of g-mode radial orders.
