Notes. The table lists K_S magnitudes taken from Schödel et al. (2010), extinction corrected with the extinction map from Schödel et al. (2010); extinction A_{K_S} adopted from the map of Schödel et al. (2010); K_S,0 magnitude assuming an intrinsic colour of (H−K_S)₀ = −0.1 for O/B stars; corresponding extinction A_{K_S}; stellar mass M_∗ using isochrones with 3–8 Myr age and solar metallicity. The last two columns denote the equivalent widths (EW) of CO and Na.
