Synopsis
The XSPEC compbb model: Comptonization, black body.
Syntax
xscompbb The xscompbb model is an additive model component.
Description
The model is described at [1] .
Example
>>> create_model_component("xscompbb", "mdl")
>>> print(mdl)Create a component of the xscompbb model and display its default parameters. The output is:
mdl Param Type Value Min Max Units ----- ---- ----- --- --- ----- mdl.kT thawed 1 0.0001 200 keV mdl.kTe frozen 50 1 200 keV mdl.tau thawed 0.1 0 10 mdl.norm thawed 1 0 1e+24
ATTRIBUTES
The attributes for this object are:
| Attribute | Definition |
|---|---|
| kT | The blackbody temperature, in keV. |
| kTe | The electron temperature of the hot plasma, in keV. |
| tau | The optical depth of the plasma. |
| norm | The model normalization: it is the same definition as used for the xsbbodyrad model. |
