\caption{The name, the HD number, the equatorial coordinates $\alpha$
and $\delta$~(J2000), the Galactic coordinates $l$ and $b$, the
formal period $P$, the amplitude in the $V$-magnitude $\Delta V$, the
photometric classification, the effective temperature
$T_{{\rm eff}}$, the surface gravity $\log g$ and the
metallicity~[\element{Fe}/\element{H}] of the seven classical
RV~Tauri stars from our sample.}
