Notes. In the Teff, log g, and [s/Fe] columns, the numbers between brackets denote the values spanned during the log g iterations, while in the C/O column they indicate the error on C/O from the spectral synthesis of the CH bands. In the L column, they indicate the luminosity error due to the error on the Gaia EDR3 parallax. The numbers in brackets in the [Fe/H] column indicate the number of Fe lines used to derive [Fe/H] and the next column indicates the standard deviation (derived from the line-to-line scatter) on [Fe/H]. The current (Mcurr) and initial (Mini) masses have been derived from the locations of the stars in the HR diagram compared to STAREVOL tracks (Sect. 6).
