Modeling wavelengths and spectral half-power bandwidths for Rayleigh equation anomaloscopes
Bibliographic record
Abstract
The recommended and required wavelengths for Rayleigh equation anomaloscopes are many and varied and without a numerical evidence base. The requirements for spectral half-power bandwidth in the German standard DIN 6160 also have no known evidence base. This paper provides data to establish requirements. The constraint on the short-wavelength limit of green was assessed by plotting chromaticities for wavelengths around the Nagel anomaloscope green and spectral half-power bandwidths up to 60 nm and identifying the combinations that lie within the first half confusion zone from the spectral locus of the deuteranope, being more restrictive than the protanopic zone. The other wavelength limits were assessed by modeling the match point and matching range using the normal and anomalous photopigment data of J. Opt. Soc. Am. A9, 1465 (1992)JOAOD60740-323210.1364/JOSAA.9.001465. The proposed wavelength limits are expressed as chromaticity, equivalent wavelength, and spectral half-power bandwidth limits. The wavelength limits are less restrictive than in DIN 6160.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
