Flux Light Curve

For this burst, 1 count = 3.34 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 1.37, the photon index is 1.95. The counts-to-unabsorbed flux conversion factor is 3.8 x 10-11 erg cm-2 ct-1. The full conversion from counts to luminosity, including distance and k-correction is 4.4 x 1047 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.
