Notes. The uncertain cluster members are the nine stars with discrepant proper motions discussed in Sect. 3.3. Except for ⟨RV⟩, the number in brackets is a flag indicating the origin of the determination: the first, second, third, and fourth digit indicates whether the value is based on GES GIRAFFE, FS GIRAFFE, GES UVES, or FS UVES, respectively. For instance, ‘1001’ means that the determination is based on GES GIRAFFE and FS UVES spectra. For ⟨RV⟩, it is the uncertainty in the average: 1-σ dispersion divided by , where N is the number of spectra used. The flags reported in the last two columns are described in Table 2. The table is available in its entirety through the CDS. A portion is shown here for guidance regarding its form and content.
