2D maps of GC density, flux density, and the ratio between them across the FoV: (a) GC density in the Fornax FoV binned into a 20 × 20 grid, (b) flux density of diffuse light within the same cells as panel (a), with all bright galaxies and other bright sources masked, (c) ratio between the GC density and the flux density of the diffuse light. The colour-bar on the left corresponds to the ratios shown in this panel.
