Center-to-limb variation of K1V and K2V distances off the line center observed by Zirker (1968) and Shine et al. (1975) (black markers), and computed for Model 1 (blue markers) and Model 2 (red markers) for the spatially averaged spectrum of Ca II K. Upper panel: absolute distances Δ λ to the features at different μ angles are shown. Lower panel: trends of Δ λ variations normalized to the mean ⟨Δ λ⟩ in each group are shown.
