Left: brighter portion of the CMD of the Carina dwarf in the V vs. B – V plane. The large colored circles represent the spectroscopic targets in this investigation. The color coding derives from the selection criteria shown in the right panel. Right: V vs. cU,B,I diagram for the same stars. This particular color combination, (U–B)–(B – I), allows us to split the RGB into old and intermediate-age populations (Monelli et al. 2014).
