xscyclabs

Context: models

Synopsis

The XSPEC cyclabs model: absorption line, cyclotron.

Syntax

xscyclabs

The xscyclabs model is a multiplivative 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:

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.Depth0   thawed            2            0          100           
   mdl.E0       thawed           30            1          100        keV
   mdl.Width0   frozen           10            1          100        keV
   mdl.Depth2   frozen            0            0          100           
   mdl.Width2   frozen           20            1          100        keV
