The data are the same as those shown above, but now the models include the effect of a stellar photosphere with unocculted stellar faculae. The bright faculae, which are ~350 K hotter than the remaining photosphere, effectively make the exoplanet appear smaller at optical wavelengths, while having little effect on the near-infrared measurements.
