Constraints on ﹩T_{\mathrm{deep}\,}﹩ for HD 209458 and TrES‐1. Lines labeled by (M/M_J, R/R_J) give allowed values of ﹩T_{\mathrm{deep}\,}﹩ vs. age for the central value of mass and a range of radii given by the radius error bar. Vertical lines give the age range from main‐sequence fitting of the parent star. The shaded region shows the range of ﹩T_{\mathrm{deep}\,}﹩ allowed, given uncertainties in mass, radius, and age.
