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

8 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 = 2.88 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.
