Characteristic frequencies for model ℳ with the parameters given in Table 1, expressed in terms of cyclic frequencies N/2π (solid), S₁/2π and S₂/2π (both dashed, S₂ residing further from the interior). The horizontal dotted line indicates the frequency of maximum power ν_max. The gravity-mode cavity is indicated by the red section with its upper boundary at r₁, and the pressure-mode cavity by the blue section (with the lower boundary at r₂) for l = 1. A prominent buoyancy glitch can be seen at r/R ≈ 0.075.
