Evaluation of the stray light from the diffraction of METIS coronagraph external occulter
Bibliographic record
Abstract
METIS (Multi Element Telescope for Imaging and\nSpectroscopy) is an externally occulted coronagraph part of\nthe Solar Orbiter payload. METIS innovative occulting system,\ncalled inverted externally occulter (IEO), consists of a circular\naperture, IEO, that acts also as the entrance pupil of the\ninstrument, and a solar disk rejection mirror (M0), placed at the\nbottom end of the coronagraph boom. M0 reflects back through\nIEO the solar disk radiation, letting the coronal radiation enter\nthe coronagraph telescope. Light diffracted by IEO enters the\ntelescope and has to be minimized with a proper shape of\nthe IEO edge. The paper describes the theoretical results of\nthe diffraction analysis extended to the scattered light by the\nprimary mirror of the telescope onto the primary focal plane.\nA summary of the entire stray light reduction capabilities of\nMETIS is also given.

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.
