CMD of NGC 5897 from Testa et al. (2001); our spectroscopic targets are highlighted as red stars. We also indicate the non-member star 11527 by a blue square. The red line is an α-enhanced, 12.4 Gyr isochrone (Dotter et al. 2008) for [Fe/H]=−1.65, shifted to a distance modulus of 15.49 and by a reddening vector of E(B − V) = 0.12, while the blue curve uses our spectroscopic metallicity of [Fe/H]=−2.04 and the best distance and reddening estimates of 15.55 mag and 0.13 mag, respectively.
