FGF "Compton-Reflection" Calculations
The following are illustrations of various
Compton Reflection spectra, similar to those
calculated in
George & Fabian (1991).

Observed EW of Fe Kalpha vs Inclination
The following are the EWs (in eV) of the Fe Kalpha
against the observed continuum assuming a centrally
illuminated (neutral, infinitely thick) slab
subtending 2pi sterad assuming cosmic abundance
viewed at an inclination angle i from the "face-on"
(basically a tabular form of
George & Fabian (1991) Fig.14).
