\tablefoot{$g_{\rm spec}$ is an apparent magnitude calculated by convolving the SDSS flux-calibrated spectra with the $g$ passband function. These represent a different epoch to the SDSS $ugriz$ magnitudes, but may be affected by ``slit losses'' due to any errors in astrometry or positioning of the fibre entrance.}
