Inconsistencies regarding the nature of globular cluster multiple population
radial distributions is a matter for concern given their role in testing or
validating cluster dynamical evolution modeling. In this study, we present a
re-analysis of eight globular cluster radial distributions using publicly
available ground-based ugriz and UBVRI photometry; correcting for a systematic
error identified in the literature. We detail the need for including and
considering not only K-S probabilities but critical K-S statistic values as
well when drawing conclusions from radial distributions, as well as the impact
of sample incompleteness. Revised cumulative radial distributions are
presented, and the literature of each cluster reviewed to provide a fuller
picture of our results. We find that many multiple populations are not as
segregated as once thought, and that there is a pressing need for better
understanding of the spatial distributions of multiple populations in globular
clusters.
