(*) Notes. - Reddening-corrected line fluxes, normalized to $F(\mbox{H$\beta$ })=1$. Equivalent widths of Balmer lines are corrected for underlying stellar absorption. The reddening coefficients, $C(\mbox{H$\beta$ })$, the value of the absorption correction, $EW_{\rm abs}$, and the reddening-corrected H$\beta $ flux, $F(\mbox{H$\beta$ }) (\times 10^{-16}$ erg cm-2 s-1) are listed for each region. In the nuclear region, only H$\beta $ and H$\beta $ could be measured, so we were unable to compute $EW_{\rm abs}$ and  $C(\mbox{H$\beta$ })$ simultaneously; to determine the latter we assumed $EW_{\rm abs}=3.0$. The quoted uncertainties include measurements, flux-calibration and reddening coefficient errors.
