The Swift Burst Analyser. I. BAT and XRT spectral and flux evolution of gamma ray bursts

The paper describes a new, versatile interface and archive for all GRBs observed by Swift during its lifetime (past and those still to come). The user has the option of constructing all spectrophotometric information, with different time intervals and energy cuts in real time, and of receiving not only the low and intermediate level products but also systematically processed, high-level science products. The paper shows an example of how to use the archive and provides examples of analyses.
