  \caption{\label{msxxxx_table2}Parameters of the comparison radio galaxy sample of Willott et~al. (\cite{Willott2002}): 
   Spectral indices, $\alpha$$_{\rm cm}$, fitted to the total cm wavelengh
   data with an accuracy of about 5\%.
   Via $F_\nu \propto \nu^{\alpha}$ the
   850~$\mu$m synchrotron fluxes are extrapolated from the cm 
   fluxes with a formal uncertainty of about 30$-$40\%.      }

$^{a}$ Actually $\alpha$$_{\rm cm}$ refers to $\alpha$$_{\rm cm-850~\mu m}$,  
due to the low 850~$\mu$m upper limit.
