Notes. In the Teff and log g 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 CH regions and in the L column, they indicate the luminosity error due to the GDR2 error on the parallax. The metallicities [Fe/H] have been obtained from the Fe abundance analyses. The numbers in brackets in the [Fe/H] column indicate the number of lines used to derive [Fe/H] and the next column indicates the standard deviation (derived from the line-to-line scatter) on [Fe/H]. BCK is the bolometric correction in the K-band as computed from the MARCS model atmospheres. The masses have been derived from the locations of the stars in the HR diagram compared to the STAREVOL tracks (Fig. 16). The last column lists whether the star is Tc-rich (“Y”) or Tc-poor (“N”) from the analysis of its Tc lines (Sect. 2.3).
