XSbkn2pow

class sherpa.astro.xspec.XSbkn2pow(name='bkn2pow')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC bkn2pow model: broken power law with two breaks.

The model is described at [1].

PhoIndx1

The power law photon index for energies less than BreakE1.

BreakE1

The first break energy, in keV.

PhoIndx2

The power law photon index for energies greater than BreakE1 but less than BreakE2.

BreakE2

The second break energy, in keV.

PhoIndx3

The power law photon index for energies greater than BreakE2.

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.
