The BAT spectrum was fitted with a cut-off power-law. The cutoff energy was 45.6 keV and was not allowed to evolve. See caveats for details.

All data uses absorption N_H=0.407 × 10²² cm^-2 at z=0.

The fit to the T₉₀ spectrum was used to create the plots in this section.
T₉₀ was 66.4, from -7.8 to 58.5
The spectral fit used was a cut-off power-law with photon index: 0.7 and cut-off energy 45.6 keV.
