HR diagrams for the program stars and the reference sample from Paper I. Also shown are the microlensed bulge dwarfs of Bensby et al. (2013) and their local disk comparison sample (Bensby et al. 2014) and the stellar parameters for bulge sample analyzed here as determined by Lecureur et al. (2007). As a guide for the eye, isochrones with [Fe/H] = 0.0 and ages 1−10 Gyr are plotted using solid light gray lines. Furthermore, one isochrone with [Fe/H] = −1.0 and age 10 Gyr, and one with [Fe/H] = +0.5 and age 10 Gyr are plotted using dotted dark gray lines (Bressan et al. 2012).
