Synopsis

The XSPEC eebremss model: electron-electron bremsstrahlung spectrum.

Syntax

xseebremss

The xseebremss model is an additive model component.

Description

The model is described at [1] .

Example

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

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

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.T        thawed            1         0.05        1e+10        keV
   mdl.eperh    frozen          1.2            0           10           
   mdl.Redshift frozen            0       -0.999           10           
   mdl.norm     thawed            1            0        1e+24

ATTRIBUTES
