Upper panel: cumulative distributions of the heliocentric radial velocities for bulge stars in the RC (black; this work), K giants (green; Zoccali et al. 2008) and M giants (orange; Kunder et al. 2012). All the stars are located in the same field at galactic coordinates (0, −6). A Kolmogorov-Smirnov test shows that RC stars and M giants have radial velocity distributions that are similar, with a confidence of 71%. In contrast, K giants have a radial velocity distribution that is more peaked at VHelio = 0 km s-1 with 89% confidence of being different from RC stars. See text for discussion. Middle and lower panels: histograms and cumulative distributions for heliocentric radial velocities of bulge stars in the BRC and FRC, respectively. The two distributions differ from each other, with a confidence of 99.95%, according to the Kolmogorov-Smirnov test.
