$^a$ Times indicate the beginning of every observation. \\
$^b$ Effective time spent on-source. \\
$^c$ Days before ($-$) or after (+) periastron. Periastron passage occurred at 2008-11-08, 2008-12-20, and 2009-01-30 (see \citealt{koh97}).  \\
$^d$ ATCA configuration for the observations. When including all antennae, the {\it uv}-coverage from the ``6''-configurations is regular, from the ``1.5''-configurations slightly bimodal and from the EW- and \mbox{750-configurations} (compact configurations) it is strongly  bimodal.
