  We present the results of computations performed with a new
photoionisation-transfer code designed for hot Compton thick media. Presently
the code solves the transfer of the continuum with the Accelerated Lambda
Iteration method (ALI) and that of the lines in a two stream Eddington
approximation, without using the local escape probability formalism to
approximate the line transfer. We show the influence that the approximations
made in the treatment of the transfer and of the atomic data can have on the
broad band UV-X spectrum and on the detailed spectral features (X-ray lines and
ionization edges) emitted/absorbed by an X-ray irradiated medium. This transfer
code is coupled with a Monte Carlo code which allows to take into account
direct and inverse Compton diffusions, and to compute the spectrum emitted up
to hundreds of keV energies. The influence of a few physical parameters is
shown, and the importance of the density and pressure distribution (constant
density, pressure equilibrium) is discussed.
