Data were analysed using HEASOFT version 6.29
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).
All data uses absorption NH=1.343 × 1022 cm-2 at z=0.

The fit to the T90 spectrum was used to create the plots in this section.
T90 was 4.2, from -0.9 to 3.3
The spectral fit used was a power-law with photon index: 0.0
Count-rate light curves are available from GCN.
