Field-decontaminated CMD of NGC 1754 in the radial annulus between 5′′ and 30′′ (black dots), with the best-fit BASTI isochrone superposed as a red line. The orange-shaded envelope represents the 1σ uncertainty region of the best-fit isochrone. The best-fit values for the reddening E(B – V), distance modulus (m – M)0, age (t), and metallicity ([Fe/H]) are also labeled.
