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. \end{table}
