CMD of NGC 5466. The turn-off magnitude of the fiducial sequence (An et al. 2008) is represented by the blue horizontal line. Lower panel: color distributions of dwarfs (dotted line) and giants (solid line) of the cluster, separated with the limit of the TO magnitude. The distribution of the giants show a second peak, with its maximum represented by the red vertical line. Dashed lines indicate the width of the peak. Left panel: luminosity function of the cluster.
