\caption{\label{tab_gaussmod}The best fit Gaussians as mentioned in the
text. {\em a} labels the major axis of elliptical Gaussians. {A}, {B1}, and {B2} were
only fitted by circular Gaussians, because the  locations of components of lower
flux density can be fitted more reliably with less degrees of
freedom. The flux density errors are $\sim$$5\%$, the uncertainties of the
location, and size of the Gaussians range between 0.2$-$0.5 of the
beamsize depending on the respective flux density.}
