Scatterometer for measuring the BRDF of the heat rejecting mirrors of the CCOR compact coronagraphs
Bibliographic record
Abstract
We designed and manufactured a benchtop scatterometer for measuring the bidirectional reflectance distribution function (BRDF) of the heat rejection mirrors (HRMs) for the Compact CORonograph 3 (CCOR-3) that is planned to be on board the European Space Agency’s (ESA) Vigil spacecraft. CCOR-3 is the third in a series of white-light solar coronagraphs that uses an external occulter to image the faint corona around the Sun to detect Coronal Mass Ejections (CMEs). The CCOR-3 instrument is very sensitive to straylight bouncing off the HRMs and illuminating the back of the external occulter in the center of the instrument’s field of view. This simple, compact scatterometer is constructed with mostly off-the-shelf components and allows for rapid and efficient analysis of the straylight performance of the HRMs.

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.
