Notes. The sky distribution of the sources is shown in optical and NIR images in Fig. 4. The projected distance (dS 269) between the Gaia sources and maser position S 269 (06:14:37.6410,+13:49:36.6930). The sources are organized by proximity to the water mater emission with the closest first. The three first rows are the optical stars that were found within the size of the HII region S 269 defined by Godbout et al. (1997) as 3.9 pc × 2.8 pc and are likely to be associated with the S 269 HII region (Sect. 4.5).
