Synopsis

The XSPEC zbbody model: blackbody spectrum.

Syntax

xszbbody

The xszbbody model is an additive model component.

Description

The model is described at [1] .

Example

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

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

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.kT       thawed            3       0.0001          200        keV
   mdl.redshift frozen            0       -0.999           10           
   mdl.norm     thawed            1            0        1e+24

ATTRIBUTES

The attributes for this object are:

Attribute	Definition
kT	The temperature of the object, in keV.
