Notes. (a) We
consider the solar value for the luminosity of a single WNL star to the
broad He II 4686 emission line (SV98
method). (b) We
consider a metallicity-dependent value for the luminosity of a single
WNL star to the broad He II
4686
emission line (CH06 method). (c) Total
number of O stars after correcting by the ionization of the WNL stars
(Eq. (10))
using the SV98 method. (d) Total
number of O stars after correcting by the ionization of the WNL stars
(Eq. (10))
using the CH06 method. (e) The
number of WCE stars and the WCE/(WCE+O), WCE/WNL and WR/(WR+O) ratios
were computed assuming the metallicity-dependent (CH06) method. (f) Total
number of O stars after correcting by the ionization of the WNL and WCE
stars (Eq. (10))
using the CH06 method. (g) This
coincides with the WR/(WR+O) ratio when no emission from WCE stars is
detected. (h) This
considers the total number of O stars after correcting by the
ionization of the WNL and WCE stars derived using the CH06 method. (i) Using
the empirical calibration given by Schaerer & Vacca (1998,
Eq. (11)).
(j) Considering not
only the flux of the broad He II
4686 flux
but also the N III
4640 and C IV
4658 fluxes.
(k) Number of WCE
stars computed using the C IV
4658 line.
