Fraction of candidate GCs in each of the eight angular bins as shown in Fig. 1. We focus on the subsamples A, B, and C in yellow, light blue, and purple, respectively as defined in Fig. 2 and Table 1. The top panel shows the azimuthal variation of the fraction of GCs in the inner halo (5 < R < 30 arcmin) and the bottom panel the outer halo (30 < R < 130 arcmin). The shaded regions show the associated 1σ uncertainties. The stellar position angle is along NE–SW. To guide the eye, the grey dashed lines show an azimuthal variation for a mock ellipsoidal distribution of points aligned along the Cen A stellar PA.
