The table provides the object identification (Col.~1), the 
number of the aperture (Col.~2),
the corresponding radius of which 
is given in Table~9, and the {\it EW} of H$\beta$~emission as derived 
from the O[III] and H$\alpha$ 
emissions (Cols.~3 and~5 respectively).
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.
