User Interface aspects of the standard analysis environment, such as Image/plot display (UI2), Command line interface & scripting (UI4), and GUI & Web access (UI5) are not shown explicitly.
1 This tool also performs periodicity tests and the results can be used to refine ephemerides2 These tools can also take as input binned data from other instruments, e.g., GBM; the corresponding DRMs must also be available.

ConclusionsConclusions
• Try to use the tutorials • e.g. start from gtobssim to create your “own” sky and then
reanalyze the DC2 sky on the same region• They are proved to be effective in getting the users really
involved in GLAST analysis• Follow carefully tomorrow’s tutorials on real DC2 sky
