The table provides in Col.~2 the number of the aperture, the correspondent radius of which 
is given in Table~\ref{table9}, and the estimate of the {\it EW} of the O[III] and~H$\alpha$ (Cols.~3 and~5
respectively) obtained from the subtraction of  the template galaxy, NGC~1426. 
Column~4 gives the quality of the measure, obtained as the ratio between the
estimated emission ($F_{\rm gal}- F_{\rm templ}$) and the variance
of the spectrum in the O[III] wavelength region, $\sigma_\lambda$. 
When the emission is lower than the variance the quality is set to~0. 
When the emission is between~1 and 2~$\sigma_\lambda$ or larger than 2~$\sigma_\lambda$
the quality is set to~1 and~2 respectively. 
The entire table is given is electronic form at the CDS.
