Mass and mixing-length parameter of selected reference models. Upper left: Distribution of initial stellar masses for selected reference models. Lower right: Distribution of mixing-length parameters for selected models. Lower left: Scatter plot showing the mixing-length parameters versus the initial stellar mass for selected stellar models. The stellar models were selected following the selection process described in Sects. 3 and 4 using the fiducial model. The models were selected from the M, α_MLT-grid. The black dashed lines and the grey lines refer to the actual mean and the input value, respectively.
