Similar to Figure 8, but here we show a Richardson et al. (2003) model based on the gray P–T profile computed in Section 4.4 (solid black line) compared to the observed results—large red points with error bars (spectroscopy) and black circles (photometry). The band integrated contrasts predicted for a gray atmosphere are represented by blue stars (spectroscopy) and green stars (photometry). As in Figure 8, the effective temperature of the planet, T_eff, is shown in the upper left, with uncertainties based on the χ² distribution, taking into account only the spectroscopic data. A gray atmosphere P–T profile is ruled out because it fails to account for the 6.3 μm bump and for the Charbonneau et al. (2008) 3.6 μm eclipse depth. The minimum reduced χ² value for this fit, assuming that only T_eff is free, is . Again, we only used the spectroscopic points for the fit and the calculation. As in the blackbody case, here there is only one degree of freedom, T_eff.
