Map of the WFI sample. All BSSs detected in the WFI sample are marked as filled circles, and the concentric annuli used to study their radial distribution are shown as solid lines, with the inner and outer annuli corresponding to ﹩r=115^{\prime \prime }﹩ and ﹩r=800^{\prime \prime }﹩, respectively (see Table 2). The circle corresponding to the tidal radius (﹩r_{t}\simeq 21.5^{\prime \prime }﹩) is also shown as dashed‐dotted line. The BSSs lying beyond r_t might represent a BSS previously belonging to M5 and now evaporating from the cluster.
