Scientific paper
The Dudley catalog of color-magnitude diagrams for the globular clusters in the Galaxy (Philip et al., 1976) is analyzed statistically to determine how the horizontal branch affects the integrated UBV colors. The color correction Delta(B-V) is always negative. For metal-rich clusters (Fe/H greater than -1.1), the absolute value of Delta is small; for metal-poor clusters, Delta is independent of the horizontal-branch morphology.
