UCD fraction (fUCD = NUCD/(NUCD + Nnuc)) as a function of projected cluster-centric distance for the Fornax (blue) and Virgo (black) clusters. We used a virial radius of 1.55 Mpc for the Virgo cluster (Ferrarese et al. 2012). The shaded regions show the 1σ binomial uncertainty. The dotted and dash-dotted green lines show the predicted UCD fractions depending on whether the UCD progenitor galaxies contain gas or not, respectively.
