Probability density function for the surface gravity log g from asteroseismology. The filled circle with the solid line and dotted line indicate the value derived from spectroscopy with its 1σ and 3σ uncertainties, respectively. The red-hatched region between the two vertical solid red lines is the 1σ range, containing 68.3% of the log g distribution. The blue vertical dashed line corresponds to the log g value of the optimal model solution of the lowest S²-value.
