RR Lyrae stars and Baade-Wesselink method. V. Photometric and radial velocity measurements of BH Pegasi, RX Eridani, SS Leonis, UU Virginis and X Arietis.

Almost simultaneous measurements in the Geneva seven-colour photometric system and in radial velocities with the spectrometer CORAVEL for five RR Lyrae field stars were obtained in order to apply the Baade-Wesselink method to this kind of variable stars. In this paper the observational data on these stars are presented; the analysis of their physical parameters will be published in the forthcoming paper of the series.
