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.

Known limitations: This is the separately labeled monochrome SC2210_BW guide-camera curve, not the main IMX571 sensor curve.
The chart labels QE (%); ZWO reports an estimated peak near 92% at 500 nm. Measurement uncertainty and optical-window contribution are not separated.
Other SC2210 cameras are linked through the documented sensor identity, not a claim of identical complete-camera response.
