Comparison of the N profiles as functions of internal mass (top panel) and the period spacings of the γ-modes as functions of the eigenperiods (bottom panel). The blue line represents the fiducial model, while the red model incorporates a δ-distribution glitch in the N profile located within the radiative core. The fiducial model is not displayed in the bottom panel, as it would be indistinguishable from the black line, which represents the ΔP_a of the red model. Notably, the periodicity in the bottom panel corresponds to the location of the δ-distribution, and the maximum period spacings measured closely match ΔP_{a, until Discont}. This value reflects the asymptotic ΔP we would obtain if the g-cavity extends from the position of the glitch to the outer boundary.
