Abstract
The instrument lineshape (ILS) of an on-axis monochromatic plane wave diffracted by the aperture stop is first calculated. This corresponds to the diffracted lineshape of a point source in the center of the field of view (FOV). This diffracted lineshape is then compared to the contribution, without diffraction, of a finite field of view on the ILS. With this comparison, a condition is derived for the diffraction to be a negligible effet on the ILS. The condition depends only upon the throughput and upon the minimal wavenumber observed. When the condition is not respected, numerical calculations must be carried to include the contribution of the diffraction on the ILS.

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
