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

17 snapshots of PC data are unreliable because no centroid could be determined. 6 bins are affected and have been hidden [Why does this matter?]. List affected times/bins.

Flux Light Curve

For this burst, 1 count = 2.78 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 0.313, the photon index is 1.805357844. The counts-to-unabsorbed flux conversion factor is 4.3 x 10-11 erg cm-2 ct-1. The full conversion from counts to luminosity, including distance and k-correction is 1.4 x 1046 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.
