\caption{\label{solOrbitales}
Fitted orbital elements to the radial-velocity measurements for the six stars, 
characteristics of their planet candidate companions and properties of the fit. 
When necessary, we replaced the fit error by the confidence interval value 
issued from Monte-Carlo simulations (see text).
The $m_{\rm 2}\sin i$ value is based on the~$M_{\ast}$ listed in 
Table~\ref{carEtoiles}. 
$N_{\rm meas}$ is the number of measurements that are effectively used in the orbital 
solution fit. 
$\langle\epsilon_{\rm RV}\rangle$ is the mean measurement error and $\sigma({\rm O-C})$ 
is the weighted rms of the residual. 
Comparison of the two values gives an indication of the amount of "jitter'' which 
can also be appreciated from the $\chi^{2}_{\rm red}$ value 
(the reduced~$\chi^{2}$ equal to $\chi^{\rm 2}/\nu$ where~$\nu$ 
is the number of degrees of freedom).
