Synopsis

The XSPEC nsmax model: Neutron Star Magnetic Atmosphere.

Syntax

xsnsmax

The xsnsmax model is an additive model component.

Description

The model is described at [1] . It has been superseded by xsnsmaxg .

Example

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

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

mdl
   Param        Type          Value          Min          Max      Units
