Left panel: large-scale distribution of RRLs (black dots) in the vicinity of the globular cluster M62. Right panel: zoom-in the M62 region (indicated by a red box in the left panel), showing individual RRL stars in our sample, with the cluster tidal radius overplotted. Most of the cluster RRLs are located within 5rh ≈ 5 arcmin of the cluster center (blue dots). The filled red circles designate RRLs with Ks < 14.5, while the blue open circles designate the RRLs outside the cluster tidal radius. The black and orange arrows point to the Galactic center and to the Galactic plane, respectively. The black dotted line curve is the orbital path of the cluster.
