Spatial distribution of the pressure perturbation in a meridional plane for two low frequency modes (radial order n = 2, azimuthal order m = 0) involved in an avoided crossing occurring around Ω = 40%Ω_k, as modeled by ACOR. Left: at low rotation velocities, mode #1 is dominated by an ℓ = 1 component and changes nature to become dominated by ℓ = 5 as the velocity increases. Right: at low rotation velocities, mode #2 is dominated by an ℓ = 5 component and changes nature to become dominated by ℓ = 1 as the velocity increases.
