Line profiles as a function of τ (for ﹩\beta =0.1﹩). Primary photons are generated at the bottom of the outflow. Left: Line profiles for the pure scattering case; right: that for the scattering plus absorption case. In each case, the fixed parameters are ﹩E_{0}=6.6﹩ keV and ﹩kT_{e}=0.1﹩ keV. The normalization of the direct nonscattering line component is suppressed for ﹩\tau =2﹩. The real normalizations are ﹩A_{N}=1.35\times 10^{6}﹩ and ﹩1.29\times 10^{6}﹩ for the diffusion and diffusion + absorption cases, respectively.
