Caption: Figure 9.

Pulsational radial velocity curve (points) and the radius variation (solid lines) of the Cepheid over one pulsation cycle. To obtain this RV curve the orbital motion was removed from the measured radial velocities. The full range of ﹩{\rm{\Delta }}R﹩ is ﹩5.7\mbox{--}6.7\,{R}_{\odot }﹩, depending on the assumed p-factor (1.2–1.4).
