  \caption{The three circular Gaussian components used for
  modeling. Their continuum flux densities are listed. The absolute
  flux density scale is uncertain by~20\%, but this does not affect
  relative flux densities; see Sect.~\ref{subsec:cal}. These components
  are overplotted on the image in Fig.~\ref{fig:image}.}\label{tab:model}
