xszwndabs

Context: models

Synopsis

The XSPEC zwndabs model: photo-electric absorption, warm absorber.

Syntax

xszwndabs

The xszwndabs model is a multiplivative model component.

Description

The model is described at [1] .


Example

>>> create_model_component("xszwndabs", "mdl")
>>> print(mdl)

Create a component of the xszwndabs model and display its default parameters. The output is:

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.nH       thawed            1            0           10 10^22 atoms / cm^2
   mdl.WindowE  thawed            1         0.05           20        keV
   mdl.redshift frozen            0       -0.999           10           

ATTRIBUTES

The attributes for this object are:

nH

The equivalent hydrogen column (in units of 10^22 atoms/cm^2).

WindowE

The window energy, in keV.

redshift

The redshift of the absorber.

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
