Low AA0.5 array interferometry

With the delivery of the remaining Low AA0.5 stations scheduled for PI24, a critical milestone will be the demonstration of array-level interferometry.

This will require substantial work across the project, including:

1. Successful integration of each station into the array, such that station beam data can reach the CSP.
2. Verification of synchronisation and timing across multiple stations.
3. Updating of the Low telescope model to accurately represent each station as-built, and configuring software for deployment accordingly (see SP-4584).
4. Integration of station beam pointing and tracking. As of PI23, this functionality has not yet been shown to work correctly in the MCCS subsystem, let alone demonstrated when driving the telescope using TMC.
5. Verification of station beams, including beam back-rotation.
6. Array pointing and tracking. This requires system-level integration of delay polynomial functionality, which has been tested between TMC and CBF, but not yet integrated.
7. Working with science commissioning to perform candidate observations for a "first light" image.

Many of these activities are already captured by planned integration and verification activities. This feature brings together these and other essential activities and aligns them towards a critical project milestone. We expect this goal will only be realised through collaboration with many other teams.
