Brunt-Väisälä profiles of four models with different CBM schemes, which were all stopped at Y_c = 0.3. We indicate the overshoot region in orange, which is fully chemically mixed with the convective core. The region in green indicates the semi-convective region, where ∇_rad = ∇_ad. Finally, we indicate the region over which N/r was integrated in the trapped mode scenario (red) and in the non-trapped mode scenario (purple).
