(g′−i′)₀ color versus radius plot. The black dots represent the 3818 GC candidates. The blue and red dots are the blue and red peaks of the color distributions divided into bins as explained in this section. The green dots represent the medians between the blue and red peaks. The blue, red, and green lines are the linear fit of the peaks. The blue and red stars represent the peaks of the total color distribution. The effective radius of the galaxy is r_eff = 1.7′, which at the distance of NGC 4696 corresponds to 21.02 kpc.
