Contour plot of ﹩\chi ^{2}_{\nu }﹩ for the SED fits in the ﹩( \omega ,\ T^{\mathrm{pole}\,}_{\mathrm{eff}\,}) ﹩‐plane. The ﹩\omega ﹩ range is limited to the 1 ﹩\sigma ﹩ range from CHARA/FLUOR fits (see Fig. 6). The polar surface gravity is fixed at ﹩\mathrm{log}\,( g) _{\mathrm{pole}\,}=4.1﹩. The labeled contours denote the 1 and 2 ﹩\sigma ﹩ regions from the ﹩F﹩ test. The cross marks the location of the best‐fit model, ﹩\chi ^{2}_{\nu }=8.7﹩.
