Gaia DR2 proper motion scatter plot (panel a), Gaia DR2 parallaxes vs. μ_δ (panel b), RV distribution (panel c), and EW(Li) as a function of the effective temperature (panel d) of all GES targets (black symbols). Objects selected as confirmed (probable) cluster members are indicated as red (cyan) dots. The red histogram in panel c is the RV distribution of the confirmed cluster members, while dashed red lines are the limits used for the selection of RV candidate members.
