The XSPEC redge model: emission, recombination edge.
xsredge The xsredge model is an additive model component.
The model is described at  .
>>> create_model_component("xsredge", "mdl") >>> print(mdl)
Create a component of the xsredge model and display its default parameters. The output is:
mdl Param Type Value Min Max Units ----- ---- ----- --- --- ----- mdl.edge thawed 1.4 0.001 100 keV mdl.kT thawed 1 0.001 100 keV mdl.norm thawed 1 0 1e+24
The attributes for this object are:
The threshold energy, in keV.
The plasma temperature, in keV.
The flux in the line, in units of photon/cm^2/s.
