Contour plot of ﹩\chi ^{2}_{\nu }﹩ in the ﹩( \omega ,\ \psi ) ﹩‐plane for ﹩T^{\mathrm{pole}\,}_{\mathrm{eff}\,}=10,250﹩ K and ﹩\mathrm{log}\,( g) _{\mathrm{pole}\,}=4.1﹩. The labeled contours denote the lower and upper 1σ range, and a 2 σ contour, from the F test. The cross marks the best fit, ﹩\chi ^{2}_{\nu }=1.31﹩, while the brightest region has a ﹩\chi ^{2}_{\nu }=3.25﹩ (see Fig. 6).
