Abstract
Astronomers from around the world have proposed designs for a new radio telescope that would have a collecting area about two orders of magnitude larger than any in existence today. The Large Adaptive Reflector, proposed by Canadian researchers, is one such design for this telescope. It uses a multi-tethered aerostat to support the telescope receiver at the focal point. Initial studies – both experimental and simulation-based – have been made on the ability of this system to accurately position the feed in the presence of disturbances due to the turbulent wind. This paper discusses a study of design improvements to the system with a view to further reducing the receiver motion. These design improvements focus on reducing perturbations that originate at the aerostat and are transmitted through the tether that attaches the aerostat to the receiver. A simulation is used to evaluate the effectiveness of a number of passive and active approaches. An experiment is then performed to further evaluate one of the passive approaches. Results show that the confluence point motions might be reduced by 30-50% from the baseline design, but at a cost of increased complexity and weight for the system.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
