Portion of the CMD of NGC 2243. Small dots represent V and V − I data taken from Kaluzny et al. (1996), while squares, triangles, and diamonds mark the positions of red giants, variables, and blue stragglers taken from the literature (WEBDA database). Circles refer to our targets, where the position of the most-probable single stars and binaries or non-members (from our radial velocity analysis) are marked in green and blue, respectively, while red giants from the literature (WEBDA database) are in red.
