Left panel: projected radial distribution of GCs and UCDs in the Fornax cluster, see also Fig. 3. The upper plot with the red curves corresponds to the distribution within 50 kpc, with x-axis limits on the top. The lower plot with the blue curves corresponds to the distribution outside of 50 kpc, with x-axis limits on the bottom. Solid lines are UCDs (M_V <  −10.25 mag). Dotted lines are bright UCDs with M_V <  −11.0 mag. Dashed lines are GCs (M_V >  −10.25 mag). There is mild evidence (92% significance according to a KS test) of a more extended distribution of bright UCDs compared to GCs within the inner 50 kpc. Right panel: cumulative radial distribution of UCDs (black, red, and blue curves), compared to that of dwarf galaxies (magenta) in the postulated progenitor magnitude range of  −18.5 < M_V <  −14 mag (Bekki et al. 2003); see also Fig. 3. The maximum of the various curves have been re-normalized to represent the respective total number of objects in each sample.
