Comparison of spectroscopic ﹩\mathrm{log}g﹩ vs. transit-derived ﹩\mathrm{log}g﹩ for transiting-planet host stars. There is a tendency (red solid line) for the spectroscopic ﹩\mathrm{log}g﹩ to be overestimated at high ﹩{T}_{\mathrm{eff}}﹩ and underestimated at low ﹩{T}_{\mathrm{eff}}﹩, by ∼0.1 dex. The sense of this trend is in the same sense as the systematics observed in the masses derived from spectroscopic ﹩\mathrm{log}g﹩ for the radial-velocity planet hosts (Figure 9, right panel). The correction previously suggested by Mortier et al. (2014; solid black line) is somewhat larger than what we find here.
