Δ ⟨ T ⟩ changes of the temperature stratifications of the ⟨ | B_z | ⟩ = 80 G and ⟨ | B_z | ⟩ = 0.5 G snapshots versus the optical depth τ₅ (solid red line). The Δ ⟨ T ⟩ values have been obtained after averaging the temperature over surfaces of equal optical depth τ₅. The symbols indicate the differences between the mean temperatures Δ ⟨ T_line ⟩ in the formation layers of the Fe i line centers derived for the same snapshots; they are given against the mean line center optical depths ⟨ τ_{5(line center)} ⟩ calculated in the ⟨ | B_z | ⟩ = 0.5 G snapshot. Circles, squares, crosses, and filled circles denote the same sets of lines as in Fig. 4. The symbols with triangles indicate the mean optical depths where the Fe i line wings originate.
