\begin{table}%t1
\caption{Flux intensities of the main emission lines detected,  measured on the extracted spectra (no slit losses correction applied yet). 
The first column indicates the label of the spectrum as specified in 
Fig.~\ref{fig:pos_fend}.
In the next eight columns we report
the observed fluxes of~{[O\sc ii]}~(3727~\AA), H$\beta$
(4861~\AA), {[O\sc iii]} (4959 + 5007~\AA), {[O\sc i]} (6300~\AA),
H$\alpha$+{[N\sc ii]}  (6563, 6548 and 6584~\AA) and  {[S\sc ii]} (6717~\AA), respectively. Fluxes are in~$10^{-16}$~[erg~cm$^{-2}$~s$^{-1}$]. 
The last column shows the $E(B-V)$ derived from
the Balmer decrement, as described in the text.  The last two rows report the fluxes for the two nuclei: the southern consists of spectra~\#4, 5 and~6, the northern of~\#13 and~14. The nuclear fluxes are larger than the sum of fluxes in individual spectra, because they were measured on total nuclei extractions and not computed as sums.}
