\caption{\label{tab5}Comparison between the Hipparcos distances and those derived from the
parameters of the modeling solution in Table~\ref{tab4}. Only formal errors quoted 
in Table~\ref{tab4} were taken into account. As explained in the text the actual 
distances may have a bit larger uncertainties.}
