Notes. Second column lists with its internal errors, i.e. the method precision. For the total uncertainties, the estimated model accuracy error of ±48 K (as discussed in Sect. 5.1) must be added in quadrature. The third column lists alternative temperatures consistent with scale. The method by which they were derived and their corresponding sources are indicated with the following codes: IntK20: direct interferometry in Karovicova et al. (2020). Ph: IRFM-based photometric calibrations in Casagrande et al. (2021) using Gaia Bp – Rp colours, its errors are those of the calibration in the corresponding source. Hk: direct IRFM in Hawkins et al. (2016). Ca10: stands for direct IRFM in Casagrande et al. (2010). Ca21: direct IRFM in Casagrande et al. (2021). The fourth column lists surface gravities derived from Mg triplet lines (values in Table A.1 averaged), determined accurate in Sect. 5.4. The fifth column lists iron abundances from neutral lines under LTE; these were shown to be biased to low values in Sect. 5.5, and therefore they must be used only for spectral modelling under LTE. The sixth column lists iron abundances from ionised lines under LTE; they were determined to be equivalent to abundances derived under non-LTE in Sect 5.6, and should therefore be preferred for calibration purposes, as they are closer to reality. The seventh column lists luminosities. The eighth column lists non-LTE-corrected Mg abundances, to which −0.07 dex must be added to reproduce LTE spectra; see Sect. 6.1. The star HD 175305, which has both interferometric and IRFM temperature measurements, is repeated for compatibility with Table 1. The symbol § indicates that lines (log (EW/λ) > −5.05) were included to derive [Fe I/H] and [Fe II/H]. [Fe I/H] values indicated with an asterisk were not derived here but were extracted from Buder et al. (2021). log ɡ values in parentheses are log ɡiso offset-corrected values; see Sect. 5.4. log ɡ values accompanied by a star symbol were derived from asteroseismologic measurements in Sect. 4.4. This table is also available at the CDS.
