Derived model for the luminosity distribution of GC candidates towards dwarf galaxies. Left panel: Inferred magnitude distributions for the fit carried out within the range 20.5 < I_E < 25, excluding two-thirds of the bright GCs (as in Fig. A.2). The distributions for all GC candidates for the background GCs (exponential) and for the dwarf-galaxy GCs (Gaussian) are shown in black, red, and green, respectively. Right panel: Ratio of the dwarf GCLF to the background GCLF in the model, with ratios of one and 1.6 highlighted.
