\tablefoot{The listed triangles
of baselines refer to the astrometric stations E (East), C (Center), W (West),
and N (North), and the imaging stations W7 and E6. $\rho$ and $\theta$
(measured east from north) refer to the position of the secondary
relative to the primary component. $\sigma_{\rm maj}$ and $\sigma_{\rm
min}$ and PA refer to the major, minor axis, and position angle of the
error ellipse of the position measurement. The shape and orientation of this
error ellipse is directly related to the synthesized beam.}
