Mr. Student watches as: Observation Sequencer
Picks observation from Queue
Passes information to subsystems:
- Target description -> Telescope Control System
- Instrument Configuration -> Instrument Control System
- Data Reduction Recipe -> Data Reduction System (via data header)
- Keeps Observing Sequence for itself
Ensures subsystems are configured
Runs the Observation Sequence
May run other Observation Definitions if they do not interfere (do not use telescope, do not use same instrument…)
