Comparison of the total mass of unresolved binaries with the stellar masses of the cluster members provided in the literature. (a) HR24; (b) Khalatyan et al. (2024); (c and d) Individual and total stellar masses i.e. including the masses of companions provided by AMD23. The red (solid), orange (dash-dotted) and the blue (dashed) lines indicate the q = 0, q = 0.5 and q = 1 relations, respectively. The dashed black line in panel (d) is the one-to-one line, and the pink circles in panel (c) are the inconsistent AMD23 stellar masses reported for BH 99 members (see text for details).
