Synopsis

The XSPEC diskpn model: accretion disk, black hole, black body.

Syntax

xsdiskpn

The xsdiskpn model is an additive model component.

Description

The model is described at [1] .

Example

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

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

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.T_max    thawed            1       0.0001          200        keV
   mdl.R_in     thawed            6            6         1000        R_g
   mdl.norm     thawed            1            0        1e+24

ATTRIBUTES

The attributes for this object are:

Attribute	Definition
T_max	The maximum temperature in the disk, in keV.
R_in	The inner disk radius, in units of Rg (GM/c^2).
norm	The normalization of the model: see [1] for details.
