Distribution of the projected distance of the sample UDGs (plain red) and of the parent Yagi et al. (2016) Coma cluster UDG catalogue (plain black) compared to the average Einasto profile derived by van der Burg et al. (2016, dashed black) and a distribution with no UDGs within 10 Mpc (dotted blue). A constant UDG density within 10 Mpc would closely follow the latter, given the x-axis range. The van der Burg et al. (2016) Einasto distribution provides a reasonable fit to the Coma cluster UDGs; a distribution without UDGs within 10 Mpc or with a constant UDG density are disfavoured.
