Notes. Run A: log g was fixed to 3.0 dex (atmosphere model grid point closest to log g = 3.034 dex reported in Table 4, column “with SED+PARSEC”); wavelength range 4700−5700 Å. Run B: log g was fixed to 3.1 dex (atmosphere model grid point closest to log g = 3.115 dex reported in Table 4, column “without SED+PARSEC”); wavelength range 4700−5700 Å. Run C: log g was treated as a free parameter; wavelength range 4700−5700 Å. Inner binary, both components; values of log g were fixed to 4.5 dex (Table 4); fixing vmicro and [M/H] as well, because spectra were really noisy; wavelength range 5100−5630 Å.
