Contemporaneous photometry and radial velocities of RR Lyrae stars
Contemporaneous BVRI photometry and radial velocities of seven RR Lyraevariables covering nearly the full span in Delta S and including the RRcstar T Sex are reported. Over 3000 BVRI measures at 100 s timeresolution and over 400 radial velocity measures are included. Thephotometric uncertainties are of order + or - 0.007 mag in V, (B - V)and (V - R) and + or - 0.014 in (R - I). The radial velocityuncertainties range from + or - 3.8 to + or - 8.0 km/s, correlated withthe metal deficiency. Light, color, and velocity curves are given.
