The BAT spectrum was fitted with a cut-off power-law. The cutoff energy was 224.7 keV and was not allowed to evolve. See caveats for details.

All data uses absorption N_H=0.418 × 10²² cm^-2 at z=0.

The fit to the T₉₀ spectrum was used to create the plots in this section.
T₉₀ was 407.1, from 88.0 to 495.2
The spectral fit used was a cut-off power-law with photon index: 1.4 and cut-off energy 224.7 keV.
