From 2016 March, the light curve plots support interactive zooming and exploring. See the jsPlot documentation for details.

2 snapshots of PC data are unreliable because no centroid could be determined. 2 bins are affected and have been hidden [Why does this matter?]. List affected times/bins.

Flux Light Curve

For this burst, 1 count = 4.12 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 2.1, the photon index is 2.105098348. The counts-to-unabsorbed flux conversion factor is 7.8 x 10^-11 erg cm^-2 ct^-1. The full conversion from counts to luminosity, including distance and k-correction is 3.0 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.
