xspexmon

Context: models

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:

mdl
   Param        Type          Value          Min          Max      Units

ATTRIBUTES

The attributes for this object are:

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 heaver 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.

XSPEC version

CIAO 4.11 comes with support for version 12.10.0e of the XSPEC models. This can be checked with the following:

% python -c 'from sherpa.astro import xspec;
print(xspec.get_xsversion())'
12.10.0e
