XSbknpower

class sherpa.astro.xspec.XSbknpower(name='bknpower')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC bknpower model: broken power law.

The model is described at [1].

PhoIndx1

The power law photon index for energies less than BreakE.

BreakE

The break energy, in keV.

PhoIndx2

The power law photon index for energies greater than BreakE.

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.
