Photon distribution over deflecting angles. The outflow shell is radially illuminated by the central source radiation. Top: ﹩\tau =1﹩; middle: ﹩\tau =2﹩; bottom: ﹩\tau =4﹩ and ﹩\beta =0.1﹩. In fact, we find in our simulations that the angle distribution of the scattering component weakly depends on τ, but there is a big difference in the normalization of the direct (nonscattering) component ﹩A_{N}﹩ for which the ratio of ﹩A_{N}( \tau =4) / A_{N}( \tau ) =\mathrm{exp}\,( -4+\tau ) ﹩.
