Glitch parameters and signature with and without penetrative convection. Top: amplitudes a₁ (dotted lines), a₂ (dashed lines), and A_max (solid lines) (Eq. (11), (12), and (15)) as functions of the extent of the PC region in pressure scale height for models B1 (left panel) and B2 (right panel) at X_c = 0.15. The dot-dashed lines represent the BSCZ. Bottom: ratios r₀₁₀ according to the frequency for the same models. The error bar represents the typical mean uncertainty on the ratios, such as the one obtained for KIC 10162436.
