Empirical distribution functions obtained from 1000 Kolmogorov-Smirnov tests performed between the Li EWs sample corresponding to M35 and those of other clusters. Left: Pleiades Li EWs sample (see Figs. 8 and 9). For each test we have randomly picked 48 Li EWs from the M35 sample (blue), that is, the size of the Pleiades sample, and compared them with the Pleiades sample (black). Right: M34 Li EWs sample (see Fig. 10). For each test we have randomly picked 14 Li EWs from the M35 sample (blue), that is, the size of the M34 sample, and compared them with the latter (red). The range of Gaia colours employed in each case is written in each panel. We selected G and K stars for the comparison between M35 and the Pleiades, but only K stars in the comparison with M34 due to the few data available for this cluster.
