$^a$ {\label{foot:36}The individual component fluxes and sizes have uncertainties of about~15\% and~10\%, respectively, within the model. The additional uncertainty range of the flux contribution of the larger component due to the lack of data at short spatial frequencies (Sect.~\ref{sec:49}) is indicated with dots.}
