XSgabs

class sherpa.astro.xspec.XSgabs(name='gabs')

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 renamed Strength to match the XSPEC definition. The name Tau 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).
