Physical parameters of RR Lyrae stars in NGC 6171
D. Deras, A. Arellano Ferro, S. Muneer +2
We present an analysis of VI CCD time-series photometry of the globular cluster NGC 6171. The main goal is to determine individual physical parameters for single-mode RR Lyrae star…

uvby(-) photometry of high-velocity and metal-poor stars X. Stars of very low metal abundance: observations, reddenings, metallicities, classifications, distances, and relative ages
W. J. Schuster, T. C. Beers, R. Michel +2
uvby(--) photometry has been obtained for an additional 411 very metal-poor stars selected from the HK survey, and used to derive basic parameters such as interstellar reddening…
