From 2016 March, the light curve plots support interactive zooming and exploring. See the jsPlot documentation for details.
1 snapshots of WT data are unreliable because no centroid could be determined. 828 bins are affected and have been hidden [Why does this matter?]. List affected times/bins.
16 snapshots of PC data are unreliable because no centroid could be determined. 4 bins are affected and have been hidden [Why does this matter?]. List affected times/bins.

Flux Light Curve
For this burst, 1 count = 3.29 x 10-11 erg cm-2 (observed flux) (Automatic spectrum).
Note that this is an time-averaged conversion factor: the true value may evolve with time.

Intrinsic Luminosity Light Curve
The light curve below shows the unabsorbed luminosity in the GRB comoving frame 0.3-10 keV band. The assumed redshift is 2.938, the photon index is 1.948538283. The counts-to-unabsorbed flux conversion factor is 3.7 x 10-11 erg cm-2 ct-1. The full conversion from counts to luminosity, including distance and k-correction is 2.7 x 1048 erg ct-1. Details were taken from the -mode automated spectral fit Note that these are time-averaged values: the true properties may evolve with time.
