Comparison of the calibrated α values with Trampedach et al. (2014a). Similar to Trampedach et al. (2014a), the BV version of MLT is chosen to plot our α values. In Trampedach et al. (2014a), the T(τ) relation based on their 3D models (Trampedach et al. 2014b) is adopted for constructing the atmosphere part of their 1D models. Unlike the present work, their 1D models include turbulent pressure and the α calibration was performed by matching temperature in the adiabatic bottom part of a convective envelope. Their α values obtained by the above procedure are presented as the magenta dots. They also tested with the VAL-C T(τ) relation, and reported that the α value becomes 0.09 larger for the solar model than the case of the T(τ) relation based on the 3D models (the magenta star). The solar marks indicate the solar model.
