Test(s)

013b: Operational Modes - Science Modes

This test shall verify correct transitions between the various science observation modes and proper operation of the LAT in those modes. The test shall involve all observation modes: Sky Survey Mode (non-rocking as well as various rocking profiles), Pointed Observation Mode, and Repointed Observation Mode.

016: LAT Performance Monitoring and Operations

This test shall verify that the FSW operates properly in every Science Mode, monitoring event data for integrity, tracking changes in event and detector statistics, and generating a report of any detected anomalies.
