   The second column shows their NVSS flux density. The third and
    the fifth columns give the average flux densities at 4.85~GHz and
    10.45~GHz measured at Effelsberg, respectively.  Columns~4 and~6
    give the rms scatter in those measurements.\\
  ${}^{\dagger}$ The average values are produced by pure detection
    cases. Only measurements of $\textit{SNR} \ge 5\sigma$ are accepted.\\
  ${}^{\ddagger}$ Source showing intense variability. Marked with
    red in the repeatability plots at 10.45~GHz.
