Astro mode
Emission-line overlay on the active single-profile plot. Values are the source's own native samples (or a labelled linear interpolation).
About this spectrum4 notes
- Warning: Response scope is unknown; do not interpret this response as a bare-sensor measurement. Dataset interpretation
- Warning: Physical configuration is not documented; the response cannot be assigned to a confirmed optical configuration. Dataset interpretation
- 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: measured
- Primary measurement: a direct laboratory observation (or community submission recorded as measured). Not a mirror, not an estimation.
- Type: measured
- Measured response; measurement alone does not establish quality or confidence.
- Origin: Community
- Community provenance; origin does not establish measurement type, quality or confidence.
- Quality: unassessed
- Quality has not been assessed; no grade is inferred. Canonical release: no per-leaf scientific-quality assessment is asserted; the source-side claim is preserved verbatim.
- Confidence: unassessed
- Confidence has not been assessed; no confidence level is inferred. Canonical release: no claim about the per-leaf measurement precision is asserted; the upstream 'as is' wording (where present) is preserved.

Alternative Siril estimate (photon-response assumption)
The primary estimate assumes energy response and divides by wavelength before normalization. This alternative assumes photon response. The source does not establish which interpretation is correct.
