Notes. The first column contains the [α/Fe] value of the sampling grid (the fit was always performed using the [α/Fe]=0.0 grid). Columns 2–4 contain – for scenario E1 – the median (q50) and the 16th and 84th quantiles (q16 and q84) of the relative errors in mass, radius, and age. Columns 5–7 contain the same quantities for scenario E2. Columns 8–10 refer to the equal-Z scenario. Values obtained from scaling relations are also reported.
