Data were analysed using HEASOFT version 6.29
The data between 1.2×108 and 1.2×108 s were taken during the XRT anomaly. The PC data may be unreliable.
From 2016 January, the light curve plots support interactive zooming and exploring. See the
jsPlot documentation for details.
Also, from the same date, the first plot on this page is the observed flux
in the native band of each instrument (including UVOT where available).
The BAT spectrum was fitted with a cut-off power-law. The cutoff energy was 90.8 keV and was not allowed to evolve. See caveats for details.
All data uses absorption NH=0.057 × 1022 cm-2 at z=0 and 0.43 × 1022 cm-2 at z=0.8049.

■ XRT (all modes)
The fit to the T90 spectrum was used to create the plots in this section.
T90 was 2.9, from -0.2 to 2.7
The spectral fit used was a cut-off power-law with photon index: 0.0 and cut-off energy 90.8 keV.
Count-rate light curves are available from GCN.
