$\begin{figure} \par\includegraphics[width=8.8cm]{3899fig3.eps}\end{figure}$ Figure 3: Comparison of the $\rm H\alpha$ luminosity and $\sigma$ with the L- $\sigma$ relationships obtained by Terlevich & Melnick (1981, dashed line) and Rozas et al. (1988, dotted line). Luminosities of the narrow component (open square) and total luminosities (solid squares) are shown, both corrected for slit loss and extinction. The crosses indicate the $\rm H\alpha$ total luminosities before slit loss correction to give an impression of the effect.

$\begin{figure} \par\includegraphics[width=17cm]{3899fig5.eps}\end{figure}$ Figure 5: Ratios of [OIII]/ $\rm H\beta$ (solid squares) for the three clusters. The vertical scale is on the lefthand axis and ratios of [NII]/ $\rm H\alpha$ (open squares) with the vertical scale displayed on the righthand axis.

$\begin{figure} \par\includegraphics[width=8.8cm]{3899fig6.eps}\end{figure}$ Figure 6: Profiles of the $\rm H\alpha$ and [OIII] 5007 lines ( upper panel). Position of the spatial centroid of $\rm H\alpha$ ( center pane). Position of the spatial centroid of [OIII] (bottom panel). The position of the continuum is indicated by a dashed line in the center and bottom panels, while the 0 in the vertical scale indicate the average position of the emission line.
