Stellar mass (top left), convective core mass (top right), and stellar age (bottom left) difference between the IM solution (cf. Sect. 4.3 and Table 3, column IM solution) and the RM solution (cf. Sect. 4.3 and Table 3, column RM solution) as a function of stellar surface gravity. The age difference as a function of the stellar mass difference between these two solutions is shown in the bottom right panel. All differences are expressed in percent relative to the RM solution values; the solid line depicts a linear fit in each of the four cases. The Spearman’s rank correlation coefficient (ρ) and the p-value of null hypothesis that there is no correlation between the two sets of variables are listed in each panel.
