CFLD_SR, continuum intensity I_c, line source function S_l, line absorption coefficient k_l , temperature, logarithmic density and V_z structures at λ = 4040.07 for two single rays of the 3D snapshot located in bright and dark areas on the stellar disk (orange and green colors indicate rays 2 and 1, respectively, in Fig. 6) and for the corresponding 1D-RSG model of Table 1 (blue dashed line). Vertical lines correspond to local maxima of CFLDs.
