Notes. For each of 11 areas with associated massive star candidates, table lists number of massive star candidates (n), weighted average distance and its weighted standard deviation (Dist.) computed from n individual values given by Bailer-Jones et al. (2021), weighted average distance and its weighted standard deviation, and average colour excess derived from confirmed OB-type stars listed in Table 4. Additionally, we provide the colour excess and its adopted range.
