\caption{Observed and reddening-corrected emission line intensities, 
$F(\lambda)$ and $I(\lambda)$, respectively (normalized to H$\beta=100$). 
Positions~A, B and C correspond to $\Delta\delta=0\arcsec$, 8\arcsec~N, and 7\arcsec~S, respectively. The spectrum of ESO~370-9 was obtained at $\Delta\delta=44\arcsec$~S.}
