Notes. Numbers of stars with valid (set of) measurements for a given chemo-physical parameter found in Gaia-ESO (second column) and Gaia (fourth column) and numbers of stars valid (set of) measurements found in the intersection between Gaia-ESO and Gaia (fifth column). The third column gives the number of stars with valid (set of) measurements found in Gaia-ESO when restricted to the sample S_j indicated in the title of the table’s sub-block. [α/Fe] is obtained by averaging individual abundances of α elements for Gaia-ESO, while it is a globally fitted estimate for Gaia. We note that the intersections listed in the last column of the table may have a smaller number of data-points if one requests also valid estimates for the uncertainties of the studied parameters.^(a)For Gaia-ESO, the final census of spectroscopic binaries is not yet available (Van der Swaelmen et al., in prep.). This number is the preliminary number of SB1, SB2, SB3 and SB4 uncovered in the final GES DR5.1. ^(b)This number relies on published data: it takes into account the SB1 discussed in Merle et al. (2020) and the SB2, SB3 and SB4 discussed in Van der Swaelmen et al. (2023). However, these two publications are based on the fifth internal GES data release (iDR5), so a dataset slightly smaller than the GES DR5.1.
