Comparison of two period spacings of mixed dipole modes within the observable region of the spectrum derived from different levels of smoothing applied in the radiative core. The cyan dashed line indicates ν_max, while the black dashed line denotes the asymptotic ΔP. Additionally, the grey lines correspond to the radial modes. The shown ΔP_a and radial modes are representative of both models, as they are indistinguishable in this scale. Notably, we observe clear differences in their period spacings, even in areas where dipole modes are detectable.
