a) Spectral types from Crowther et al. (2016, WN5h stars) and Caballero-Nieves (in prep., all other stars). b) This quantity is expressed as L13.6 = log LE>13.eV/L⊙. c) Formal uncertainties assuming a Teff of 50 kK. In reality uncertainties on all parameters are larger due to the uncertain Teff. d) No good fit obtained to iron pseudo-continuum; assumed value closest to Bestenlehner et al. (2020) for UV normalisation. e) Cross-contamination of the spectrum as a result of crowding (as in Bestenlehner et al. 2020, with the addition of R136a8).ƒ) Severe cross-contamination of the spectrum as a result of crowding: R136a6 consists of H19 and H26, see Sect. 2.1. g) Potential spectroscopic binary (as in Bestenlehner et al. 2020).

Notes. This table contains initial and current (evolutionary and spectroscopic) masses, ages, H-I, He-I and He-II ionising radiation Q0, Q1, Q2, H-I ionising luminosity, Eddington factors for electron scattering ΓEdd,e, and the Teff derived from the iron continuum and used for the normalisation of the UV spectra Tiron. This table is complimentary to Tables A.1 and A.2 and is based on the optical + UV runs.

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.
