\caption{\label{lines_tab}Observed emission line fluxes (unit:
10$^{-14}$~W~m$^{-2}$~$\mu$m$^{-1}$) for the most prominent
lines which are well separated (no blends). The fluxes were
absolute calibrated with respect to the ASAS-3 photometry ($m_V =
11\fm34$) by folding standard filter curves. The main uncertainty
originates from the "definition'' of the continuum around the
lines.}
