Inconsistencies regarding the nature of globular cluster multiple populationradial distributions is a matter for concern given their role in testing orvalidating cluster dynamical evolution modeling. In this study, we present are-analysis of eight globular cluster radial distributions using publiclyavailable ground-based ugriz and UBVRI photometry; correcting for a systematicerror identified in the literature. We detail the need for including andconsidering not only K-S probabilities but critical K-S statistic values aswell when drawing conclusions from radial distributions, as well as the impactof sample incompleteness. Revised cumulative radial distributions arepresented, and the literature of each cluster reviewed to provide a fullerpicture of our results. We find that many multiple populations are not assegregated as once thought, and that there is a pressing need for betterunderstanding of the spatial distributions of multiple populations in globularclusters.
