Temperature profiles calculated for the set of T_eff and log (g) parameters used to generate the spectra in Fig. 3. Triangles and squares on the log (g) = 4 profiles indicate the bottom of the iron and silicate clouds respectively. One BT-Settl profile (green) is also shown for comparison, the star corresponding to the bottom of the dust location. The radiative-convective boundary is shown as a cross on the same profiles.
