\caption{The observed \hii\ regions in \sexa\ and \sexb.  The centres of
the slits are reported.  The adopted names of \hii\ regions are from
Hodge et~al. (\cite{hodge94}) for Sextans A and from Strobel et~al. (\cite{strobel}) for Sextans B. The HII region not identified in
previous works is labeled as \hii~H. \label{Tab_pos_hii} }
