Synopsis

The XSPEC qsosed model: AGN SED model

Syntax

xsqsosed

The xsqsosed model is an additive model component.

Description

The model is described at [1] .

Example

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

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