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:
