First light results of REVOLT-COPPER: a pyramid wavefront sensor on a 1.2m telescope
Bibliographic record
Abstract
REVOLT (Research, Experiment and Validation of Adaptive Optics with a Legacy Telescope)—the local adaptive optics (AO) system at National Research Council's Herzberg Astronomy and Astrophysics Research Centre (NRC-Herzberg)—is an on-sky testbed for a variety of new technologies and algorithms, including the Herzberg Extensible Adaptive optics Real-time Toolkit (HEART). In this paper, we show first light results from a recent expansion of REVOLT to include a second closed-loop wavefront sensing path using a pyramid wavefront sensor (PWFS), REVOLT-COPPER (Canadian On-sky Platform for PWFS Experimental Research). We show successful operation of a modulated PWFS using the Gemini Planet Imager 2 (GPI2) HEART pipeline where we use a PWFS pixels-to-modes reconstructor, bypassing the need to calculate PWFS slopes first. We also present analysis of REVOLT-COPPER's performance and discuss the on-going research and development effort at NRC-Herzberg.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
