GC distributions around NGC 1052-DF2 (left panel) and NGC 1052-DF4 (right panel). Red circles indicate the positions of the spectroscopically confirmed GCs (van Dokkum et al. 2019; Shen et al. 2021), while the positions of the GC candidates found in Montes et al. (2020, 2021) are denoted with orange circles. The radii of the green circles (R_GC) represent the spatial location where half of spectroscopically confirmed GCs are found. The radii of the light blue circles instead, represent the spatial location where half of all GCs candidates are found.
