\caption{{\it Stars with \Ha\ in emission}: Errors in stellar and wind 
parameters given in Table~\ref{para}. $\Delta$ \teff\ in kK,
$\Delta$ $\beta$ adopted as $\pm 0.1$, $\Delta$ $\log Q_1$ is the error in $Q$-value due 
to uncertainties in \Ha\ line fit, $\Delta$ $\log Q_2$ is the
error in $Q$-value arising from uncertainties in \teff\ and $\Delta$ $\log Q_t$ 
is the total error. All values have to be preceeded by
a $\pm$sign.\label{err1}}
