Synopsis
The XSPEC pexmon model: neutral Compton reflection with self-consistent Fe and Ni lines.
Syntax
xspexmon The xspexmon model is an additive model component.
Description
The model is described at [1] .
Example
>>> create_model_component("xspexmon", "mdl")
>>> print(mdl)Create a component of the xspexmon model and display its default parameters. The output is:

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