SKAO Staged Delivery, Array Assemblies And Layouts

The purpose of this document is to provide the astronomy community with a single point of reference that describes the array assemblies (AA), and the list of antennas along with their coordinates in each array assembly that will be available to the scientific community from the start of Science Verification through to the full design baseline. The content presented in this document is complemented by a Python package that allows users to simulate interferometric observations using both the entirety of the dishes or stations available during a particular AA, or a subset of those available (i.e. a “subarray”). Both Low and Mid telescopes can provide up to 16 concurrent subarrays, offering a lot of flexibility to both operations and science observing.
