Energy light curves

NEW Show: Flux Luminosity

Flux Light Curve

For this burst, 1 count = 3.80 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 3.899, the photon index is 2.007157822. The counts-to-unabsorbed flux conversion factor is 5.5 x 10^-11 erg cm^-2 ct^-1. The full conversion from counts to luminosity, including distance and k-correction is 8.6 x 10⁴⁸ 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.
