CMD of the BUL-SC29 field with overplotted theoretical isochrones (Valcarce et al. 2012). Isochrone ages, metallicities, and helium abundances are indicated near the top-left corner of each panel. Sub-solar isochrones are α-enhanced, and solar-scaled otherwise. The metallicity range covered by the bulk of the stars in the BUL-SC29 field is 0.002 ≲ Z ≲ 0.060, as derived in Sect. 5. Open circles mark stars that are most likely blue stragglers (see text for more details).
