Notes.  The arrows indicate whether we infer the absolute magnitude (Mν) from a known distance modulus D.M., or whether the distance is calculated from Mν as obtained by the subtype magnitude calibration (cf. Table 3).

(a)

Masses are calculated from luminosity after Langer (1989) using his WC relation for WC stars and his WNE relation for WN/WC stars.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
