Recently observed GRBs

Swift-XRT GRB lightcurve repository

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.
