Colour–magnitude diagrams for the open clusters NGC 2158, NGC 2383, and NGC 2489. The BV data were taken from Carraro et al. (2002), Subramaniam & Sagar (1999), and Piatti et al. (2007), and we adopted a cluster radius of 1.́5, 2.́5, and 5′ for NGC 2158, NGC 2383, and NGC 2489, respectively. The symbols are the same as in Fig. 4.
