\caption{Column 1: identification number of the \hii~regions (from the 
NGC~1530 \hii~region catalogue, Rela\~no et~al. \cite{Rela05}); Col.~2: decimal 
logarithm of the \ha~luminosity (in erg s\me). The errors represent 
uncertainties in the \ha~luminosity due to the image noise and the 
uncertainties in the determination of the \hii~region area 
(as described in Zurita \cite{Zuri01}); Col.~3: decimal logarithm 
of the \ha\ equivalent width of the \hii~regions; Cols.~4 to~7: $B, V, R, 
K{\rm s}$~broad band magnitudes of the \hii~regions corrected for Galactic 
extinction (Schlegel et~al. \cite{Schl98}); Cols.~8 to~11: number of 
data points used for the determination of the broad band colour in the 
corresponding band (see Sect.~\ref{results_hii} for more details). The 
errors in the broad band magnitudes include  uncertainties due to the 
determination of the local background for each \hii~region (see 
Sect.~\ref{metodos_fondos} for details), which  dominate the error bars. The 
asterisks highlight the \hii~regions data which rely on only one measurement of
the local background, and which are therefore more uncertain.}
