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.

estimated(estimated response; not a primary measurement)- 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.

Image area and resolution are documented for this reference camera; other cameras may use a different crop or binning mode.
Player One manual explicitly identifies the camera as using the monochrome IMX432; dimensions are that camera readout.
Sensor-level response data is available. Camera filters and windows can change the complete camera response.
