Abstract: Context: Gamma Ray Burst models predict the broadband spectral evolution andthe temporal evolution of the energy flux. In contrast, standard data analysistools and data repositories provide count-rate data, or use single fluxconversion factors for all of the data, neglecting spectral evolution. Aims: Toproduce Swift BAT and XRT light curves in flux units, where the spectralevolution is accounted for. Methods: We have developed software to use thehardness ratio information to track spectral evolution of GRBs, and thus toconvert the count-rate light curves from the BAT and XRT instruments on Swiftinto accurate, evolution-aware flux light curves. Results: The Swift BurstAnalyser website this http URL contains BAT, XRT andcombined BAT-XRT flux light curves in three energy regimes for all GRBsobserved by the Swift satellite. These light curves are automatically built andupdated when data become available, are presented in graphical and plain-textformat, and are available for download and use in research.
