Description of the RPW_SCIENCE DETECTION-DEFAULT State.
Context and purpose
The RPW_SCIENCE DETECTION-DEFAULT state is the main operating science state for SBM_DETECTION mode, to be applied on-board during the Solar Orbiter science operations.
Description
This section gives more details about the state. The SBM1/SBM2 parametrization of the DETECTION-DEFAULT state can be set using the specifc sequences AIWF038B, AIWF038C (TDS) and AIWF039A, AIWF039B (TDS) with formal parameter default values.
The "State" section gives the general state of the sub-system (i.e., S/W mode). The "configuration" section gives the detailed configuration of the sub-system. The "Attributes" section lists the TC and/or formal parameters which are allowed to change the configuration.
