Scheduling Service Mode Programmes
Scheduling service programmes for execution is determined by three main factors:
- Programme priority group,
- Observing constraints imposed by the Principal Investigator, and
- Actual observing conditions.
The Observing Constraints are the set of criteria related to the target position and external conditions required by a particular observation that controls when that observation can be executed. Once the observation has been executed, the comparison between the specified constraints and the actual execution conditions then determines whether or not the observation met the user-specified requirements.
For more details, see the section about the critical observing constraints.
