Nucleation fraction between the Fornax main cluster (blue) and the Fornax A group (orange) as a function of projected distance (using NGC1399 and NGC1316 as the centre for the Fornax main cluster and Fornax A group, respectively). The shaded regions denote the 68% binomial confidence interval. The number of galaxies in each bin are annotated in the plot. The dashed vertical lines denote the same limits as in Fig. 1.
