Bright GC candidates density maps of the full ERO-D FoV (left column), with zooms on the NGC 1549-NGC 1553 pair (middle column), and on NGC 1546 (right column). The colour scale is the same for both zooms, where the density fields were re-evaluated locally using the samples within the cutouts. All GCs, blue GCs, and red GCs are represented in the upper, middle, and lower rows, respectively. Blue and red GCs are defined relative to the median I_E − H_E colour of the GC candidates, which is not indicative of an intrinsically bimodal population within our data.
