Results from the IACOB-GBAT analysis (regarding log g) of 119 multi-epoch spectra of the SB2 star HD 199579, sorted according to the radial velocity of the spectrum. Uncertainties from the analyses are included as vertical error bars. The uncertainty in the original analysis in log g (±0.1 dex) is shown as a gray area around the value obtained there, which is also the median value of all estimates (log g = 3.9 dex).
