\caption{Orbital solutions corresponding to the $R$$V$s of the N~{\sc iv} $\lambda$4058 emission line within different   data sets. The quoted errors correspond to 1$\sigma$ uncertainties.
Symbols have the canonical meaning. The last three correspond, respectively, to the mass function, the standard deviation of the fit and the number of data points involved.}
