Burst Analyser — BAT-XRT-UVOT light curves

The UKSSDC will be completely offline from around 11:00 BST (10:00 UT) on 2024 April 16 for up to 3 days. This is due to essential hardware work affecting the room in which our servers are located, and it is hoped that the work will be completed well within the window above. On-demand processing will be disabled some hours before the shutdown, and any jobs still running at the time of shutdown will be lost.

This website contains BAT, XRT and UVOT fluxed light curves of all GRBs observed by Swift. The flux conversion is time-dependant and accounts for spectral evolution. See the online documentation for details

In January 2016 the Burst Analyser was modified to include a new plot: the observed flux density. This plot, which includes UVOT data when available, is the first plot on the individual target pages. See the online documentation for details.

NEW: Guidelines for downloading XRT GRB products in bulk.
