Synopsis
The XSPEC cyclabs model: absorption line, cyclotron.
Syntax
xscyclabs The xscyclabs model is a multiplicative model component.
Description
The model is described at [1] .
Example
>>> create_model_component("xscyclabs", "mdl")
>>> print(mdl)Create a component of the xscyclabs model and display its default parameters. The output is:
