\begin{table}%T2 \caption{Stellar parameters obtained from the fits for different cases. Case A is obtained ignoring veiling effects and gravitational darkening; Case~B is obtained by accounting only for the veiling effects; for Cases~C, D, and~E, veiling effects and gravitational darkening are taken into account with a relative angular speed of the star at 80, 90, and 95\%, respectively, of its break-up velocity (see Sect.~\ref{param}).} \label{cases} %\centering \par \begin{tabular}{llll} \cline{1-3}\\[-3mm] \cline{1-3} Case & A & B \\ \cline{1-3} $T_{\rm eff}$ (kK) & 17.5 $\pm$ 1 & 19.1 $\pm$ 1 \\ $\log~g$ (cgs) & 3.30 $\pm$ 0.10 & 3.91 $\pm$ 0.10 \\ $v\sin~i$ (km~s$^{-1}$) & 176 $\pm$ 5 & 167 $\pm$ 5 \\ \hline Case & C & D & E \\ \hline $\Omega \over \Omega_{\rm c}$ & 0.80 & 0.90 & 0.95 \\ $T_{\rm eff}$ (kK) & 19.6 $\pm$ 1.5 & 19.8 $\pm$ 1.5 & 20.2 $\pm$ 1.5 \\ $\log~g$ (cgs) & 4.04 $\pm$ 0.15 & 4.08 $\pm$ 0.15 & 4.11 $\pm$ 0.15 \\ $v\sin~i$ (km~s$^{-1}$) & 170 $\pm$ 10 & 173 $\pm$ 10 & 177 $\pm$ 10 \\ $V_{\rm eq}$ (km~s$^{-1}$) & 312 $\pm$ 20 & 381 $\pm$ 25 & 453 $\pm$ 24 \\ $i$ ($^{\circ}$) & 33 $\pm$ 3 & 27 $\pm$ 2 & 23 $\pm$ 2 \\ $T_{\rm pol}$ (kK) & 20.6 $\pm$ 1.3 & 21.3 $\pm$ 1.4 & 22.2 $\pm$ 1.3 \\ $\log~g_{\rm pol}$ (cgs) & 4.08 $\pm$ 0.12 & 4.13 $\pm$ 0.12 & 4.17 $\pm$ 0.12 \\ $R_{\rm pol}$ ($R_\odot$) & 3.93 $\pm$ 0.70 & 3.67 $\pm$ 0.66 & 3.55 $\pm$ 0.64 \\ $R_{\rm eq}$ ($R_\odot$) & 4.62 $\pm$ 0.83 & 4.68 $\pm$ 0.83 & 4.80 $\pm$ 0.87 \\ $M$ ($M_\odot$) & 6.81 $\pm$ 0.81 & 6.81 $\pm$ 0.80 & 6.97 $\pm$ 0.85 \\ $L$ ($L_\odot$) & 3.35 $\pm$ 0.21 & 3.32 $\pm$ 0.21 & 3.34 $\pm$ 0.22 \\ $f_{\rm rot}$ (c~d$^{-1}$) & 1.35 $\pm$ 0.35 & 1.63 $\pm$ 0.40 & 1.88 $\pm$ 0.46 \\ dist (pc) & 205 $\pm$ 70 & 228 $\pm$ 80 & 248 $\pm$ 85 \\ \hline \end{tabular} \end{table}
