For every GRB detected by the XRT onboard Swift, a series of analysis scripts are automatically executed. These produce enhanced positions with errors as small as 1.4" (90% confidence), light curves, and spectra, which are immediately made available online at These products have been extensively verified by the XRT team, and are 'science-grade'; that is, they are generally as reliable as products generated manually by experts and can be used in scientific analysis. Our automated approach yields a uniformly derived set of products for all GRBs observed by Swift's XRT, allowing us to determine some sample statistics. We have also developed web-based versions of our software, available on-demand, to produce positions, light curves and spectra for any object observed by the XRT.
