The final page of the Science Goal allows the user to enter important scientific objectives that will determine many aspects of how the observations will be executed. These include the desired angular resolution and the largest angular structure that needs to be imaged - these determine which arrays and configurations need to be scheduled. It also includes how long these will observe for which, unlike most other radio/mm/submm telescopes, is calculated from a desired sensitivity. An example of the Control and Performance parameters is shown in Fig. 5.8, including the ACA interface.
