Azimuthal distribution of 3083 globular cluster candidates. The plots show the number of clusters (N_GC) as a function of the position angle (PA), divided in angular bins of 30°. The red line represents the interpolation with the function described in Eq. (8) to the data, the blue and magenta lines represent the angular positions of NGC 4709 and NGC 4696B respectively, the green lines represent the position angle of the peaks, and the dashed black lines represent the fit with Eq. (9). The different panels show the distributions of the total (top panel), red (middle panel), and blue (lower panel) GC samples.
