\caption{{\footnotesize CORALIE} best Keplerian orbital solutions for \object{HD~156846} and \object{HD~4113}, as well as inferred planetary parameters. Confidence intervals are computed for a  68\% confidence level  after 10~000~Monte~Carlo iterations. {\it Span} is the time interval in days between the first and last measurements. $\sigma({\rm O-C})$ is the weighted rms of the residuals around the derived solutions.}\label{table:elements}
