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. |
