Top panel: V − I, I CMD of Sextans. Gray circles are probable Sextans members based on their [Fe/H]_CaT metallicities and radial velocities (Battaglia et al. 2011). The red symbols show the stars we discuss here. Large circles are the new targets of this work. The samples of Tafelmeyer et al. (2010) and Aoki et al. (2009) are shown with smaller squares and triangles, respectively. Bottom panel: spatial distribution of these stars. The ellipse indicates the tidal radius of Sextans.
