Upper panel: radial velocity distribution of the eight RRLS with V < 16.5. The shaded histogram corresponds to the radial velocity distribution of RR c stars. Bottom panel: radial velocity distributions of thin disk A–F stars (dashed–dotted line), thick disk (dashed line), and halo (solid line) stars in the surveyed area, taken from the Besançon Galactic model (Robin et al. 2003). The dashed lines in the upper plot show the positions of the means of the distribution of each Galactic component.
