\begin{table}%T8 \setcounter{table}{7} \caption{Median values for the core dominance parameter $R$ based on two sorts of VLBI flux-density measures and the Green Bank 5~GHz flux-densities. The Green Bank and total VLBI flux-densities have been taken from Taylor et~al. (\cite{Taylor1996}). For those sources where no total VLBI flux-densities were given in Taylor et~al., we obtained the values from Paper I. The VLBI core flux-densities have been taken from Paper~I. \label{coredominance}} \small%\centering \par \begin{tabular}{c|c|ccccc} \hline\hline & Sample &Q&G&B&LPQ&HPQ \\ \hline $R_{\rm C}$ (VLBI core flux)&All &0.52 &0.33 &0.54 &0.39&0.52\\ $R_{\rm V}$ (total VLBI flux)&All &0.92 &0.84 &0.90&0.90&1.06\\ \hline $R_{\rm C}$ (VLBI core flux)&detections&0.50&0.35&0.54&0.38&0.53\\ $R_{\rm C}$ (VLBI core flux)&non-detections&0.54&0.33&0.56&0.48&0.52\\ \hline \end{tabular} \end{table}
