Zoom-in CMDs of our sample of nearby red-dwarf candidates from Fig. 7. For the three CMDs, unfilled black squares represent the objects flagged as bin because of the similarities between their astrometric information and any other near object within 30′′. Black unfilled triangles indicate objects flagged as hr, possibly containing unresolved companions. These CMDs are color-coded by the distance from the Sun, which is obtained from the Bayesian analysis of Gαìα EDR3 parallaxes of Bailer-Jones et al. (2021), with darker circles being closer.
