Swift-XRT GRB spectrum repository

This website contains a repository of Swift/XRT spectra for all GRBs which have been detected by this instrument. These spectra are suitable for scientific analysis and publication (see the usage policy). The default spectrum is a time-averaged spectrum. For some GRBs, XRT-team members may have added time-sliced spectra as well which will appear on the results pages. For more information, see the online documentation.
