Top: the GC specific frequency S_N versus absolute V-band magnitude M_V for nearby dwarf galaxies. NGC 6822 and IC 10 are shown by plus and triangle symbols enclosed in red circles. Each galaxy’s N_GC is calculated from the number of clusters that are class 1 or 2 with ages larger than 5 Gyr and Z/Z_⊙ ≤ 0.2. The grey filled circles and squares represent a sample of LG and late-type galaxies taken from Forbes et al. (2018b). Bottom: the GC system mass-halo mass relation, where the halo mass is represented by M₂₀₀. The symbols are the same as in the top panel.
