The dependence of the anisotropy on the height calculated with the FALC model (solid lines) for several f parameter values (marked near the curves), and with the FALA (dotted line) and FALF (dashed line) models for f = 0 (this implies calculations, without anisotropy alteration, see Sect. 5.2). The anisotropy was computed at 3871.2 Å in the (1, 1) bandhead (left panel) and at 3869.1 Å in a CN blend (right panel).
