Notes. The simulation name, the inner radius of the spherical shell R_i, the radius of the lower convective boundary $R_{CB}^{L}$ $R^{\mathsf{L}}_{\mathsf{CB}}$ , the radius of the upper convective boundary $R_{CB}^{U}$ $R^{\mathsf{U}}_{\mathsf{CB}}$ , and the outer radius R_o of the spherical shell are given in units of the total radius of each star, R. The temperature is provided at the lower convective boundary $T_{CB}^{L}$ $T^{\mathsf{L}}_{\mathsf{CB}}$ and the upper convective boundary $T_{CB}^{U}$ $T^{\mathsf{U}}_{\mathsf{CB}}$ . The resolution of the upper (lower) convective boundary $H_{p, CB}^{U} / Δ r$ $H^{\mathsf{U}}_{\mathsf{p,CB}}/\Delta r$ ( $H_{p, CB}^{L} / Δ r$ $H^{\mathsf{L}}_{\mathsf{p,CB}}/\Delta r$ ) is provided. The average global convective turnover time τ_conv is provided as well as its standard deviation, and the total time span for each simulation is given in units of the average convective turnover time.
