\tablefoot{Column~1: ID number of the catalogued \hii~regions; Cols.~2 and~3: equatorial coordinates; Col.~4: \hii~region radius in arcseconds; Cols.~5 and~6: eccentricity and position angle (measured North-West) of the integration apertures; Col.~7: decimal logarithm of the \ha~luminosity (in~erg~s$^{-1}$); Col.~8:  decimal logarithm of the \ha~equivalent width; Col.~9: decimal logarithm of the 24~\micron\  emission within the \hii~region apertures; Col.~10: \ha~attenuation  see Sect.~\ref{sec:dust}; Col.~11: estimate of the current star-formation rate for each catalogued \hii~region. Columns~7$-$10 include the corresponding correction for Galactic extinction (Schlegel et~al. \cite{Schlegel1998}). The SFRs were obtained after applying a correction of 25\% for [\nii]~contamination to the \ha~luminosities and dust extinction as given in Col.~10.}
