Best fit parameter ranges for the 39 stars where a 12-free-parameter optical + UV fit was done, ordered by decreasing Ṁ. First four columns (blue colours) show basic stellar parameters T_eff and log g as well as υ_eq sin i and x_He derived from the optical-only fit. The next eight columns (green to red colours) show the parameters that describe the wind and wind structure. The last two columns (pink and purple) concern the C and N abundances. The darker and lighter shaded regions correspond to 1σ and 2σ uncertainties, respectively. Note that R136a8 has no optical data and thus no optical-only fit: in this case v_eq sin i and x_He are indicated with a •.
