Notes. In the ‘Atomic Diffusion’ column, g indicates that the models include atomic diffusion without radiative accelerations and g + grad indicates that the models include atomic diffusion with radiative accelerations. In the following column ΔM0 is the value of reference mass used to compute turbulent mixing; ‘None’ means that we do not include turbulent mixing in the grid.
