Gaia DR3 extinction-corrected CMD showing the location of the Gaia BH3 companion as a red cross, and the ED-2 members (B23) as blue and empty circles. The former are high-latitude (|b|> 20°), low-extinction (E(B − V)≤0.01) ED-2 members. The sequence followed by the ED-2 stars is extremely tight, indicative indicative of their small metallicity dispersion. Their distribution is in very good agreement with the CMD of stars in the globular cluster M92 (truncated at M_G, 0 = 5), shown in the background as black dots. This implies that they are of similar age, given their comparable metallicities. The object with M_G, 0 ∼ 0.6 is an RR Lyrae type-c star (Clementini et al. 2023).
