Cumulative radial distribution of AGB stars (heavy solid line) in the innermost region of the cluster (﹩r< 100^{\prime \prime }﹩) as a function of the projected distance r from the cluster center compared with those obtained for (a) HB and RGB stars and (b) bHB, faint‐blue RGB (fRGB), and BSS stars, respectively. AGB stars are significantly more centrally segregated than RGB and HB stars. The radial distribution of AGB, bHB, and fRGB stars is nicely in agreement with that of BSS stars.
