The XSPEC pexmon model: neutral Compton reflection with self-consistent Fe and Ni lines.
xspexmon The xspexmon model is an additive model component.
The model is described at  .
>>> create_model_component("xspexmon", "mdl") >>> print(mdl)
Create a component of the xspexmon model and display its default parameters. The output is:

The attributes for this object are:
The power-law photon index.
The cut-off energy (E_c) in keV. Set to 0 for no cut off.
The reflection scaling parameter (a value of 1 for an isotropic source above the disk, less than 0 for no direct component).
The redshift of the source.
The abundance of the elements heaver than He relative to their solar abundance, as set by the set_xsabund function.
The iron abundance relative to the solar abundance, as set by the set_xsabund function.
The inclination angle in degrees.
The normalization of the model: see  for an explanation of the units.

CIAO 4.12 comes with support for version 12.10.1n of the XSPEC models. This can be checked with the following:
% python -c 'from sherpa.astro import xspec; print(xspec.get_xsversion())' 12.10.1n
