- Type
- Sensor
Response
Sensor spectrum; camera filters and windows can change the response.
- red (R)
- green (G)
- blue (B)
Astro mode
Emission-line overlay on the active single-profile plot. Values are the source's own native samples (or a labelled linear interpolation).

- 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: unknown
- Source category is not documented by the manifest. Not a measured, estimated, or mirror curve until evidence supports a label.
- Type: not documented
- Measurement, estimation or proxy derivation is not documented by this label; origin does not establish it.
- Quality: unassessed
- Quality has not been assessed; no grade is inferred. Source values and quality flags are preserved as published.
- Confidence: unassessed
- Confidence has not been assessed; no confidence level is inferred. No complete camera response or source uncertainty is documented.
