Fig. 1.
Colour-magnitude diagram showing all stars from the catalogue of Geier (2020) as dark grey circles. The composite systems analysed in this work are shown as red diamonds. At this point, no quality cuts have been performed in the astrometry, which explains the high spread. Sample C of Lindegren et al. (2018) is shown in light grey to facilitate the location of the main sequence and other evolutionary stages.
