Temperature structures of the three model atmospheres analysed in this investigation. The intrinsic CNO abundances are given in each panel. Details about each model and the synthesis produced with them is given in Table 1. Panels B and C also present the differences between the ⟨ 3D ⟩ temperature structures of model A with models B and C respectively. This has been scaled up four times relative to the y-axis to better show the temperature deviations so that every tick represents a ΔT = 50 K.
