Spatial distribution of NGC 3201 stars from Kravtsov et al. (2009) in grey dots with a greyscale density pattern. Spectroscopic targets are shown with the same symbols as in Fig. 2 for the 28 good quality member stars. Dashed outer circle shows the half-light radius (r_h = 3.1′), the internal dashed red circle is the core radius (r_c = 1.3′), and the blue dashed square delimits the region of the HST observations used here.
