Stacked radial distribution of the GC number density of dwarf galaxies (14 galaxies with stellar masses of M_* > 10⁷ M_⊙) for GCs brighter than I_E = 23 (upper panel) and GCs brighter than I_E = 24.5 (lower panel). The GC radial distance from the centres of their host galaxies (x-axis) is normalised to the host galaxy’s effective radius (R_e). The GC number density (y-axis) represents sum of GCs around all the 14 dwarf galaxies has the unit of $R_{\text{e}}^{-2}$. For a typical dwarf galaxy with R_e = 1 kpc this unit corresponds to kpc⁻² . The red-dashed curve demonstrates the best-fit Sérsic profile for the binned data and the displayed error bars. The errors correspond to Poisson uncertainties of the number of GCs normalised to the unit area.
