Left panel: kernel density estimate (KDE) smoothed distributions of the amplitude vs. period for field RRL stars from Gaia DR2 data (see Clementini et al. 2018) with the M62 RRLs (red dots) in our sample overplotted. Right panel: comparison of the Bailey diagram for stars in the main body of M62 (red dots) with the RRLs located outside of the tidal radius of the cluster (blue open circles).
