\caption{Structural parameters of the disks. $SB_{\rm c}$ is the seeing-deconvolved 
and inclination-corrected central surface brightness in mag/square-arcsec. 
$R_{\rm d}$ is the radial scale-length of the exponential disk, given in arcsec and 
in kpc. $\rm PA_d$ is the position angle of the major axis (line of nodes).
$Q_{\rm d} = b/a$ is the axis ratio of the model fit to the disk.
Each value is given for the corresponding filters {\it UBVRI}.
This table is only available in electronic form at the CDS (see footnote to title).}
