Notes. The upper and lower error bars associated with the median masses delimit the range of variability of the computed median if we take into account the objects with (T_eff, L_bol) coordinates but no mass estimate from the HR diagram in Fig. 7 because they fall outside the area covered by the model grid. When no error bars are reported, the variation on the value estimated following this approach is lower than 0.01. p-values smaller than 0.1 are reported in italic. The K-S test table is symmetric with respect to its diagonal.
