Abundance profiles resulting from overshoot mixing using Eq. (15) with the parameters ω = 0.10 (dashed) and ω = 0.14 (solid) for a 4 M_⊙ case. Not only does the extent of the overshot region grow with the increase in the free parameter, but the slope of the proton profile decreases, which results in wider effective ¹³C pockets. The convective envelope is shown as the hatched area.
