      • Completes the testing for the LOW CBF AA0.5 FAT
      • Demonstrates that delay tracking works for both the correlator and CNIC-VD
      • Enables system goal #1 to be achieved
      • Removes long standing risk of delay polynomial control loop in both software and hardware not functioning
      • Demonstrates a closed loop - delays in CNIC-VD compensated for in Correlator
      • Enables further CBF-SDP imaging tests to be run with multiple source

      The feature demo presenation is drafted here: https://docs.google.com/presentation/d/12riGfmeelIHQGpDj4uFw7nU0K8OgN2q5v1jBmRUk3tM/edit#slide=id.g112dcb28055_0_0

      The key part of the feature is now completed and will be presented at the OMC System Demo 20.4: https://confluence.skatelescope.org/display/SE/2023-11-02+OMC+ART+System+Demo+20.4

    • Demonstrated, Satisfies Acceptance Criteria

    Description

      • Assumed starting point is functional delay polynomials in CNIC and correlator (but untested)
      • Write up test documentation to describe how the CNIC-VD is configured, controlled by the LOW CBF delay polynomial simulator and processed by the correlator
      • Execute PTC#11 - delay tracking accuracy to check that the resulting visibility phases are within specifications
      • Fix any bugs in the correlator, CNIC, delay polynomial creator, and other software
      • Integrate PTC#11 into the gitlab CI pipeline (new integration repo has been created but we need to configure a pipeline using existing or new tests, and set up triggers so other repos run the integration pipeline on merge requests)
      • Fix the CNIC download rate (extremely slow writing to disk from within Tango/k8s)
