  In Paper by Titarchuk & Shrader the general formulation and results for
photon reprocessing (downscattering) that included recoil and Comptonization
effects due to divergence of the flow were presented. Here we show the Monte
Carlo (MC) simulated continuum and line spectra. We also provide an analytical
description of the simulated continuum spectra using the diffusion
approximation. We have simulated the propagation of monochromatic and continuum
photons in a bulk outflow from a compact object. Electron scattering of the
photons within the expanding flow leads to a decrease of their energy which is
of first order in V/c (where V is the outflow velocity). The downscattering
effect of first order in V/c in the diverging flow is explained by
semi-analytical calculations and confirmed by MC simulations. We conclude that
redshifted lines and downscattering bumps are intrinsic properties of the
powerful outflows for which Thomson optical depth is greater than one. We
fitted our model line profiles to the observations using four free parameters,
\beta=V/c, optical depth of the wind \tau, the wind temperature kT_e and the
original line photon energy E_0. We show how the primary spectrum emitted close
to the black hole is modified by reprocessing in the warm wind. In the
framework of the our wind model the fluorescent iron line K_alpha is formed in
the partly ionized wind as a result of illumination by central source continuum
photons. The demonstrated application of our outflow model to the XMM
observations of MCG 6-30-15, and to the ASCA observations of GRO J1655-40,
points out a potential powerful spectral diagnostic for probes of the
outflow-central object connection in Galactic and extragalactic BH sources.
