ACTIVITY TITLE: STIS Modes and Data Interfaces

ID: STIS-01

APPLICABLE SMOV REQUIREMENTS: L.10.4.5.1.1, L10.4.5.1.2, L10.4.5.1.3, L10.4.5.1.11

DESCRIPTION: STIS will be transitioned into each of its four instrument states: Hold, Boot, Operate, and Observe. It will be transitioned to all detector states for the CCD [HOLD, STANDBY (PROTECT), Operate], and the NUV and FUV MAMAs [Hold, LVon, and HVon]. Finally, the STIS engineering data (telemetry) and science data (exposures only) interfaces will be verified. These requirements will be demonstrated during normal operations. No special test will be needed to reach these instrument and detector modes and verify the data interfaces.

IMPLEMENTATION METHOD: Stored commanding, special commanding, real-time commanding.

DEPENDENCIES: N/A

DURATION: 0

DATA REQUIREMENTS: Covered under other activities.

ANALYSES & EXPECTED RESULTS: Engineering data from all modes will be examined for all correct relay states, voltage, current, temperature, and logical values (such as positions and memory states). Science data will be examined for proper formatting and contents.

COMMENTS: This activity will be satisfied during the course of normal operations, and do not require a separate proposal. However, if it is desirable to include initial STIS turn-on procedures in a proposal, rather than simply including them in a standard recovery SMS, this activity would be the place to capture that.
