Notes.

^(a)

Generic element, including Fe, Sc, Ti, V, Cr, Mn, Co, and Ni, with relative abundances to Fe as described in Gräfener et al. (2002).

^(b)

Two versions are used for the Galactic WNL models for different T_∗ regimes. The first number refers to the superlevels used for the cooler models, the second for the hotter models.

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.
