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.

- 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
- Caption calls this a relative QE curve, while the vertical axis says quantum efficiency (%). The scale is ambiguous and remains unknown.
- Published values are preserved on the 0-to-80 axis without normalization or interpretation as measured absolute QE.
- The manual does not establish whether the plotted response excludes the camera window or sensor cover glass; source scope remains unknown.
- The very low long-wavelength tail can be indistinguishable from the baseline; unobserved pixels remain missing.
