Synopsis
The XSPEC diskpbb model: accretion disk, power-law dependence for T(r).
Syntax
xsdiskpbb The xsdiskpbb model is an additive model component.
Description
The model is described at [1] .
Example
>>> create_model_component("xsdiskpbb", "mdl") >>> print(mdl)
Create a component of the xsdiskpbb model and display its default parameters. The output is:
mdl Param Type Value Min Max Units ----- ---- ----- --- --- ----- mdl.Tin thawed 1 0.1 10 keV mdl.p thawed 0.75 0.5 1 mdl.norm thawed 1 0 1e+24
ATTRIBUTES
The attributes for this object are:
Attribute | Definition |
---|---|
Tin | The temperature at the inner disk radius, in keV. |
p | The exponent of the radial dependence of the disk temperature. |
norm | The normalization of the model: see [1] for details. |
