Warning: Response scope is unknown; do not interpret this response as a bare-sensor measurement. Dataset interpretation
Warning: Physical configuration is not documented; the response cannot be assigned to a confirmed optical configuration. Dataset interpretation
Warning: Estimated response; not a primary measurement. Sources and attribution
Warning: Normalization is unknown; amplitude comparisons are not established. Dataset interpretation
Warning: Uncertainty is not documented. Missing uncertainty does not mean zero uncertainty. Dataset interpretation

Source & details

Source category: estimated: Estimated response: not a primary measurement (e.g. diffraction-grating closed-form recovery, model prediction). Independent of profile_type and quality/confidence grades.
Type: estimated: Estimated response, not a direct measurement; quality and confidence are assessed separately.
Quality: unassessed: Quality has not been assessed; no grade is inferred. Canonical release: no per-leaf scientific-quality assessment is asserted; the source-side claim is preserved verbatim.
Confidence: unassessed: Confidence has not been assessed; no confidence level is inferred. Canonical release: no claim about the per-leaf measurement precision is asserted; the upstream 'as is' wording (where present) is preserved.
