Burrows (PSU) and S.D.\nBarthelmy (GSFC) report on behalf of the Swift-XRT team:\n\nThe Swift-XRT team announce the release of a repository of GRB XRT \nspectra, available online at http://www.swift.ac.uk/xrt_spectra. This \nrepository is analogous to the light curve repository; spectra are built \nand updated automatically and posted online within minutes of data \nbecomming available. These spectra will shortly be available through the \nGCN Ground-Analysis Information page \n(http://gcn.gsfc.nasa.gov/swift_gnd_ana.html). The reliability of these \nspectra has been confirmed by the XRT team. You are welcome to use these \nspectra. Please see the full documentation, including the usage policy, at \nhttp://www.swift.ac.uk/xrt_spectra/docs.php. A paper describing their \nproduction will be forthcoming.\n\nWe have also implemented upgrades to the GRB light curve repository \n(http://www.swift.ac.uk/xrt_curves/). Users may now: 1) rebin the light \ncurves, 2) change the minimum number of counts and duration of the bins, \nand 3) define the energy ranges and grade selection criteria. In addition, \nthe source and background event lists used to create the lightcurves are \navailable for download using the links at the foot of each GRB's light \ncurve page. These event lists contain extra information, such as the \nradius of the source region and the radius of any excluded, piled up \nregion, for each event. The online documentation provides full details.",
