Absolute narrow-band v-magnitudes of Galactic WN stars based on Gaia DR2 distances. The red symbols refer to stars with detectable hydrogen, while the green filled symbols stand for hydrogen-free stars. The symbol shapes refer to the spectral subtype: “early” and “late” subtypes (WNE and WNL, respectively) and distinguish among the WNE stars between weak (-w) and strong (-s) lines (see Paper I for details). The binaries and runaways are encircled (cf. Sect. 2). The labels refer to the WR catalog numbers; if printed with slanted font, their Gaia measurement is flagged with a significant astrometric excess noise (see Sect. 3). The thick lines indicate the subtype calibration adopted in Paper I.
