XSgabs
(name='gabs')[source] [edit on github]¶ Bases:
sherpa.astro.xspec.XSMultiplicativeModel
The XSPEC gabs model: gaussian absorption line.
The model is described at [1].
Note
Deprecated in Sherpa 4.10.0
The
Tau
parameter has been renamedStrength
to match the XSPEC definition. The nameTau
can still be used to access the parameter, but this name will be removed in a future release.-
LineE
¶ The line energy, in keV.
-
Sigma
¶ The line width (sigma), in keV.
-
Strength
¶ The line depth. The optical depth at the line center is Strength / (sqrt(2 pi) * Sigma).

guess
(dep, *args, **kwargs)[source] [edit on github]¶ Set an initial guess for the parameter values.
Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.
