AbstractA study is made of deviations from the mean power-law relationship between the Galactocentric distances and the half-light radii of Galactic globular clusters. Surprisingly, deviations from the mean R h versus R gc relationship do not appear to correlate with cluster luminosity, cluster metallicity, or horizontal-branch morphology. Differences in orbit shape are found to contribute to the scatter in the R h versus R gc relationship of Galactic globular clusters. © 2012. The American Astronomical Society. All rights reserved.
