  \caption{\label{tab:Stars}The collected spectra for each stellar target, 
    giving the corresponding spectrograph, the resolving power, the 
    Julian date (HJD) and signal-to-noise ratio ({\it S/N}) for each observation.
    The {\it S/N} for \'ELODIE spectra is estimated at $5550$~\AA. Values of 
    $v~\sin{i}$ are from \cite{Royer02} and given in km~s$^{-1}$.}
