Left panel: globular cluster luminosity function of MATLAS-2019. Middle panel: distribution of R_e assuming that the intrinsic shape of the GC is a Gaussian. Right panel: distribution of R_e assuming that the intrinsic shape of the GC is a King model. The spectroscopically confirmed GCs from Müller et al. (2020) and Haacke et al. (2025) are indicated in red (hatched), the population identified in this study is in blue. The widths of the bins have been calculated using the Freedman–Diaconis rule (Freedman & Diaconis 1981). The black solid line shows a Gaussian fit to the data.
