\begin{table}%T2 \caption{\label{literatur}Gaussian model-fit results for S5~1803+784 obtained from the literature. The columns list the epoch of observation, the jet-component identification, the flux density, the radial distance of the component center from the core, the position angle of the center of the component, the FWHM major axis, and for elliptical Gaussian fits, the axial ratio and the position angle of the major axis. The final column provides a reference to the original publication.} %\centering \par \begin{tabular}{ccrrrrrrc} \hline\hline\noalign{\smallskip} (1) &(2)& (3) &(4) & (5) &(6)&(7)&(8)&(9)\\ Epoch & Id. & S [Jy] & r [mas] & $\theta$ [deg] & Ma.A.
