Diffusion factors for convective turbulence (D_conv), shear turbulence (D_sh), and effective turbulence (D_eff) as a function of the Lagrangian mass coordinate for our evolution models with M_zams = 120 M_⊙ and Z = 0.014, adopting old and new winds at an intermediate point in the main-sequence stage (X_core = 0.3). Vertical grey lines represent the total mass of both models. The symbols for the solid and dashed lines are the same as in Fig. 3.
