Notes. For the benchmark stars the first row lists the literature values, the second row the values derived in this work. For the detached eclipsing binaries three solutions are given: previous literature results in the first row, the second row provides values derived from the single epoch spectrum adopted here alone, the third row gives our results using the log(g) values and the Teff ratio (if known) from the binary solution based on the light curve and radial-velocity analysis as additional fit constraints. Uncertainties are 1σ values. (a)log(gtrue) = 3.91±0.07, see Sect. 4.3; (b)log(gtrue) = 3.55±0.07. (1) Aschenbrenner et al. (2023); (2) Nieva & Przybilla (2012); (3) Weßmayer et al.
