Distribution of the number of GCs within 2R_e for the 74 UDG sample (light grey), the 36 UDGvD15 as defined by van Dokkum et al. (2015) (pale indigo), and the 40 nucleated UDGs (bright coral). The majority of the sample (47 UDGs or 64%) are measured to have N_GC < 3, while the remaining 36% is spread across a wider range of values (N_GC = 3 − 38). A total of 21 UDGs (28%) have N_GC values consistent with zero, with the tail of the distribution extending to our most GC-rich galaxy, MATLAS-2019, with N_GC = 38. The percentage of nucleated UDGs with a large number of GCs (14 UDGs or 35% have N_GC ≥ 3) is similar to the one for the whole sample.
