\caption{{\bf Order 1.}
Cepheid angular diameters and distances, assuming the average diameter
$\overline{D}$ of Gieren et~al. (\cite{gieren98}). The diameter variation curve
$\Delta D(\phi)$ is integrated from the radial velocity curve.
Only the distance is ajusted by the fitting procedure. The error bars on $d$ are
given as in Table~\ref{results_cepheids0}.}
