Scientific paper

We present infrared (JHK) light curves and radial velocity curves for four southern hemisphere RRab Lyraes (WY Ant, W Crt, RV Oct and BB Pup) and an infrared light curve for one RRc Lyrae (AU Vir). Absolute magnitudes are determined for the RRab stars, using a combination of the infrared flux method and the Baade-Wesselink method. Including these four stars, there are now 29 RR Lyraes that have been analysed, using these, or similar, methods. The best-fitting lines to these stars are =0.21(±0.05)[Fe/H] + 1.04(±0.10) and =-2.95(±0.10) log P-1.07(±0.10), where the quoted errors are, we believe, realistic rather than formal or internal.
