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. Raster graph digitization; source measurement uncertainty is not documented.
Confidence: unassessed: Confidence has not been assessed; no confidence level is inferred. Exact chip and mode documented; complete camera equivalence is not established.

Methodology: digitized from manufacturer graph
As-is: Samples rendered verbatim: no smoothing, no interpolation, no zero-padding, no gap bridging in the browser. Documented null sparse cells render as visible gaps.
Uncertainty: Extraction tolerance is documented in the downloadable JSON; it does not quantify source measurement uncertainty.

Known limitations: The graph axis explicitly says relative response (0 to 1), although nearby text gives a measured peak QE of 79%.
Values remain relative as graphed; the 79% scalar is not used to rescale the source trace.
Camera optical configuration is not separated from sensor response.
