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 0.755, the photon index is 2.19. The counts-to-unabsorbed flux conversion
factor is 7.0 x 10-11 erg cm-2 ct-1 . The full conversion from counts to luminosity, including
distance and k-correction is 2.2 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.
