XScutoffpl

class sherpa.astro.xspec.XScutoffpl(name='cutoffpl')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC cutoffpl model: power law, high energy exponential cutoff.

The model is described at [1].

PhoIndex

The power law photon index.

HighECut

The e-folding energy of the exponential rolloff, in keV.

norm

The normalization of the model. See [1] for details, as its meaning depends on whether the “POW_EMIN” or “POW_EMAX” keywords have been set with set_xsxset.
