Abstract: We present reddening values for the lines of sight to 3256 RR0 Lyrae stars from the Galactic bulge fields of the MACHO Survey. From this sample, we derive the selective extinction coefficient RV,V R = AV =E(V − R) = 3.9, which corresponds to RV = 1:9, substantially lower than the Galactic average of RV ≈ 3.1. Reddenings to individual stars using the intrinsic and observed (V − R) colors at minimum light are obtained. Our reddenings show good agreement with other determinations.
