Line-of-sight velocity distribution of M75. Left panel: RVs of the final MUSE catalog (see Sect. 3.3) plotted as a function of the distance from the cluster center. The black dots highlight the sample of the well-measured stars (i.e., those with S/N > 20 and RV error < 5 km s⁻¹) that is used for the kinematic analysis. Right panel: empty histogram showing the number distribution of the entire RV sample, and gray histogram corresponding to the subsample of bona fide stars (black dots in the left panel).
