Analyzing data from GLAST's Large Area Telescope (LAT) will require sophisticated techniques. Because GLAST will scan the sky continuously during most of the mission, each LAT count from a given source will be detected at a different detector orientation in the LAT's large field-of-view. Sources cannot be analyzed in isolation because the point source function (PSF) is large (68% of the counts within 3.5 degrees) at low energy (~100 MeV) and near-by sources will overlap; at high energy (~10 GeV) the PSF is much smaller. The analysis of pulsars and gamma-ray bursts will be simplified by their temporal signatures. We describe the methods implemented in the software environment provided for the analysis of GLAST data, and the documentation that will be provided.
