Note: For each source component, we list its flux density, separation and position angle relative to the component fixed at the origin ( $r=0, \theta =0$), major axis, axis ratio, and position angle of the major axis. The uncertainties given here have been estimated from the exploration of the parameter space (S, r, $\theta$, a, b/a, and $\phi$), and from empirical considerations (e.g., the nominal errors of the component positions are in general smaller than 10 $\mu $ as, but to be conservative we increased this figure up to a tenth of a beam width).
a The restoring beam is an elliptical Gaussian with FWHM axes $a\times b$ [mas]. For each source, the position angle (PA) stands for the direction of the major axis, measured north through east.
b $S_{\rm peak}$: brightness peak [mJy/beam].
c $S_{\rm tot}$: total flux density recovered in the hybrid mapping process [mJy].
c rms: root-mean-square noise in the image [mJy]. Contours in the maps of the figures shown in Sects. 3.1 to 3.13 are the tabulated rms values times $(-3,3,3\sqrt{3}\cdots)$.
