Notes. The quoted errors correspond to 1σ uncertainties. The bolometric corrections are taken from Lanz & Hubeny (2003) based on our best-fit Teff and log g. The wind parameters, in the lower half of the table, are subject to very large uncertainties and should thus be taken with caution. Thevalues f1 and f2 represent the clumping filling factor and the clumping velocity factor.
