Table 6

Main results for the 42 OCs analysed, indicating, for each cluster, the number of stars from the sample detected in UVES and GIRAFFE; the number of stars with EW(Li) values; the number of stars selected as candidate members (including RV, astrometric and Li members, as well as the final members); and the number of Li-rich giant contaminants.
