Radial distribution of GC candidates in MATLAS-2019. The red profile represents the spectroscopically confirmed GCs, the GC candidates obtained in this study are in blue, and the whole GC system in green. The black line is the mass density profile of MATLAS-2019, as indicated in the right Y-axis. The errors in the GC profiles are the Poissonian error of the number of GCs per area in each annulus (i.e. $\sqrt{N_{\text{GC}}}/A$. The dashed vertical grey lines indicate 1R_e and 2R_e of the galaxy (R_e = 17.″2, Müller et al. 2020).
