Control and Performance

This 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. As the opacity of the atmosphere at mm/submm wavelengths is large and highly frequency-dependent, the user requests a sensitivity instead of a time. The OT will then derive a time estimate based on expected observing conditions, although the actual observing time may be different because of different observing conditions at the telescope (number of antennas, atmospheric conditions, etc.). Solar and VLBI observations are different as the user requests a time and does not enter a desired sensitivity.
