Distribution of the RR Lyrae stars in the range of distances from 3.5 to 9 kpc in the Bailey (period-amplitude) diagram. Stars within the tidal radius of the cluster are marked with black triangles, while those outside the tidal radius (the candidates to be debris) are indicated with red open triangles. For reference, RR Lyrae stars in ω Centauri from Kaluzny et al. (2004) are shown with star symbols. Solid and dashed lines represent the typical locus of OoI and OoII clusters (Cacciari et al. 2005).
