All About Constraints

There are two major groups of constraints for Spitzer: Operational Constraints and Observer-Imposed Constraints. These pages give a quick overview of the constraints.

Definitions: Operational Constraints - cannot be altered by the observer.
Definitions: Observer-Imposed Constraints - can be imposed (but only with scientific justification) by the observer.

Tips for Observer-Imposed Constraints

Observers should note that all constraints need to be strongly justified in the telescope proposal. Observer-imposed constraints can render observations unschedulable. Following these tips will help make your observations easier to schedule.
