$\begin{figure} \par\includegraphics[width=14cm,clip]{3067fig7.ps} \end{figure}$ Figure 7: The radial velocity curves for six NGC 1866 Cepheids. Our new data are marked with filled symbols, while data from the literature have been over-plotted as open symbols. The data are marked in the following way: LCO 1995: filled squares; LCO 1996: filled diamonds; LCO 2000: filled circles; CTIO: filled triangles; Storm et al. (2004a): open circles; Welch et al. (1991) ${\rm HJD} < 2~447~520$ : open squares; Welch et al. (1991) $2~447~860 < {\rm HJD} < 2~447~877$ : open diamonds.

$\begin{figure} \par\resizebox{8.8cm}{!}{\includegraphics{3067fig11.ps}} \end{figure}$ Figure 11: Panel a) shows the observed data set of angular diameters, $\theta$ (in micro arc-seconds), versus radius variation, $\Delta R$ , corresponding to Eq. (2) for the star HV 12198. The straight line is the bi-sector fit to the data in the phase interval [0.0, 0.8]. Panel b) shows the angular diameter as a function of phase. The points correspond to the photometrically determined angular diameters and the curve corresponds to the integrated pulsational velocity curve. In both panels the crosses represent discarded points.
