Abstract

ABSTRACT Contemporaneous BVRI and JHK photometry are given for the RR Lyrae variables SW And and TU UMa. Additional BVRI photometry is included for the variables TT Lyn and T Sex and two JHK points for UU Vir. These 331 observations supplement those already published in our series of observations of RR Lyrae variables and can be phase-locked to radial velocities given by Barnes et al. (1988, ApJS, 67, 403) and by Wilson et al. (1989, ApJS, 69, 951). We briefly discuss our new observations of TU UMa in the context of the binary model proposed by Saha and White (1990, PASP, 102, 148).
