Spatial averages of disk center intensity profiles (left panel) and normalized disk center intensity profiles with bisectors (right panel) of a fictitious low-excitation (χ = 0 eV) Fe i line plotted as functions of wavelength shift Δλ in mÅ with λ₀ = 3000 Å, computed for an arbitrary snapshot of the 3D model with  [Fe/H]  = −3.0 including coherent continuum scattering (solid lines) and treating scattering as absorption (dashed lines).
