EW(Li)-versus-T_eff diagram showing the final candidate selection (red squares) for IC 2602, a 35-Myr-old cluster. The upper envelope of EW(Li) for the cluster IC 2602 is shown in red; the upper and lower envelopes of the Pleiades cluster are shown in grey; and the turquoise line represents the upper envelope of the Hyades cluster. For completeness we show here all field contaminants of interest, colour-coded as follows: RV non-members (open grey squares), Li-rich giants (blue), giant outliers which are not Li-rich, and finally (fuchsia), NG non-members (green) and possible candidates (turquoise). For more details, we refer the readers to Sects. 3.3 and 4).
