The Swift-XRT GRB Catalogue

On 2012 September 24 all GRB light curves and spectra were rebuilt using HEASOFT v6.12. More information.

Parameter distributions

The plots below show the probability density functions of the temporal and time-averaged spectral parameters for all GRBs. Click the images for larger versions. These figures correspond to Figs. 5,6, 7a and 8a of Evans et al. (2009). See the PDF documentation for more information.

Closure Relationships

The plots below show (α, β) scatter plots for each of the different types/phases of light curves (see light-curve types), where α and β are the temporal and spectral energy power-law indices respectively. The shaded regions mark those allowed by the standard closure relationships. These figures correspond to Fig. 10 of Evans et al. (2009). See the closure relationship documentation for more information.
