Recently observed GRBs

Swift-XRT GRB lightcurve repository

We will be performing maintenance on the UKSSDC systems between 1000-1200 BST on Thursday August 17. Some services may experience brief interruptions during this time.

This website contains a repository of Swift/XRT lightcurves for all GRBs which have been detected by this instrument. These lightcurves, which are official products of the Swift/XRT team, have been extensively tested against manually-created lightcurves. Users are advised that different binning of a lightcurve can affect its detailed appearance. For more information, see the online documentation.

Usage policy

The references for these products are Evans et al. (2009, MNRAS, 397, 1177) and Evans et al. (2007, A&A, 469, 379). Please also use this acknowledgement if you use them.
