 \caption{\label{lineratio1} Observed and reddening-corrected 
line intensity ratios relative to H$\beta$\protect\footnote{All narrow emission line ratios were derived from the nuclear
spectra. After reddening correction, other Balmer line-ratios such as H$\gamma$/H$\beta$ and
H$\delta$/H$\beta$ are consistent with the recombination values within the
errors. The uncertainties are in the range of $\sim$1--15\%.}.}
