\tablefoot{Listed are new RV data (bottom panel) and 
previous RV measurements (top panel), which have been re-processed for this work. HJD is given at the middle of the exposure; 
$\sigma_{\rm RV}$ is the estimated error in the relative RVs.
An additional error of about 400~m~s$^{-1}$ has to be taken into account for the absolute RVs. \tablefoottext{a}{RV value is the average of two (three in the case of 2010 03 01) single consecutive measurements.}}
