Synopsis

The XSPEC highecut model: high-energy cutoff.

Syntax

xshighecut

The xshighecut model is a multiplicative model component.

Description

The model is described at [1] .

Example

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

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