The luminosity scale of RR Lyrae stars with the Baade-Wesselink method. I - Photometry and radial velocities
UBVRI optical and JK IR photometry and radical velocities are presentedfor a sample of 13 field RR Lyrae stars with metallicities ranging frommetal-rich to metal-poor. These stars include 11 ab-type variables, SWAnd, RR Cet, SU Dra, Rx Eri, RR Gem, RR Leo, TT Lyn, AV Peg, AR Per, TUUMa, and UU Vir, and two c-type variables, TV Boo and T Sex. Light,color, and radial velocity curves of these RR Lyrae stars are alsopresented in the paper.
