Rebin this light curve| About these products.
There are data for this object on the quick-look site. This may indicate that we are still observing this object. This light curve is thus not yet ‘final’.
Jump to: Energy light curves | Count-rate light curves.
From 2016 March, the light curve plots support interactive zooming and exploring. See the jsPlot documentation for details.
4 snapshots of WT 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.
9 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 = 4.88 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.
