Abstract
ABSTRACTWe present light curves in the B, V, and I passbands for six field RR Lyrae stars. We derive the stars’ intensity‐mean magnitudes, light amplitudes, and colors at minimum light. We compare the latter with measurements from other variables and discuss the use of (V−I) color at minimum light as a tool for measuring interstellar reddening. From 15 stars, we find the mean dereddened RR Lyrae color at minimum light to be (V−I)0 = 0.57 mag. The rms scatter of 0.025 mag indicates the precision of this value over a wide range of metallicities and pulsation periods.
