Assessment of quarter-to-quarter variations in F8-based ﹩\mathrm{log}\;g﹩ using the asteroseismic calibration sample from Chaplin et al. (2014). Top: residuals of F8-based ﹩\mathrm{log}\;g﹩ relative to asteroseismic ﹩\mathrm{log}\;g﹩, with error bars representing the rms standard deviation of the F8-based ﹩\mathrm{log}\;g﹩ across all available quarters. These error bars are in general smaller than the absolute scatter in the residuals relative to the asteroseismic benchmark. Middle: distribution of the quarter-to-quarter rms scatter in the F8-based ﹩\mathrm{log}\;g﹩. The typical quarter-to-quarter variation in F8-based ﹩\mathrm{log}\;g﹩ is ∼0.02–0.05 dex. Bottom: distribution of the ratio of ﹩\mathrm{log}\;g﹩ residuals to the quarter-by-quarter rms. The distribution is reasonably approximated by a Gaussian with σ = 2.0, indicating that the true F8-based ﹩\mathrm{log}\;g﹩ errors are a factor of 2 larger than the relative quarter-by-quarter errors for a given star.
