The final page of the Science Goal allows the user to enter important scientific objectives such as the required angular resolution and largest source scale that needs to be imaged. These determine which of the six 12-m array configurations is required, whether or not the ACA is needed and how much time is required for the observations to achieve a requested sensitivity given the spectral setup. An example of the Control and Performance parameters is shown in Fig. 5.9, including the ACA interface.
