K-band Light Curves for RR Lyrae Stars in the Globular Clusters M5 and M92

K-band photometry for the RR Lyrae stars V1 and V3 in the extremely metal-poor globular cluster M92 (NGC 6341) and V8 and V28 in the intermediate metallicity cluster M5 (NGC 5904) have been acquired during the 1987-1990 observing seasons, for use in a Baade-Wesselink analysis. A single-channel photometer as well as IR imagers have been used for the data acquisition and the results from the different systems show good agreement. The reduction procedure for these data and the resulting light curves, good to better than 0.02 mag, based on 340, 541, 284 and 212 measurements for M92-V1, M92-V3, M5-V8 and M5-V28 respectively, are presented. Preliminary distance estimates for the clusters using the (M_K)-log P relation for the RR Lyrae stars leads to values of (m - M)_0 = 14.36 for M92 and (m - M)_0 = 14.24 for M5. (SECTION: Stars)
