Radial displacement (ξ_r) computed with the Full reference state (orange) and the EnvCZ reference state (dotted blue). The top panel shows a non-asymptotic ℓ = 15, n = 5 mode with ν = 290.8 μHz, while the left panel shows a ℓ = 15, n = 5 mode with ν = 100.1 μHz, which can be interpreted as asymptotic. The vertical dashed grey lines correspond to the bounds of the radiative interior while the vertical dashed yellow lines highlight the radial location of the ν_nℓ = N boundary. On both panels, ξ_r was normalised by its maximal value.
