Recorded DATE-OBS time interpretation retained; if TIMESYS is absent it is provisionally UTC.

Saved calculation at this exposure group's midpoint. Geometric altitude assumes sea level, no terrain or refraction. Schematic orientation, not a sky photograph.

Weather does not establish seeing, transparency at the telescope, a Bortle class or a photometric correction. Missing values do not imply clear skies.

How this archive average is calculated

Each unique original exposure contributes once per valid saved metric. Arithmetic mean across all objects; RGB and DNB separate. Missing or invalid values are excluded, never zero. This descriptive reference includes the selected exposures and later nights.

Exposure, camera settings, field brightness, sampling and stellar populations may differ. Background and stellar model SNR are not normalized measures of sky quality, master SNR or detection sensitivity. A difference is not a grade.

Stored per-frame medians of stellar fits are averaged; stars are not pooled. SNR requires a positive recorded effective gain and at least five stellar estimates. Units remain separate. Unknown method versions are recorded, not invented. Small, undersampled stars may bias shape measurements.

Reading these values

Provisional stellar models: undersampled stars can bias the measurements. Differences are not quality grades. Stellar SNR is not nebular or master-image SNR.

Method and all inputs

Median/MAD comparisons stay within the same session, exposure, recorded setup and orientation. At least 12 valid frames and 75% coverage are required. Only simultaneous strong width and elongation outliers with at least 20 fitted stars can be excluded automatically. These are engineering thresholds, not a validated defect classifier. Entire-night defects and satellite trails may escape these metrics; pixel rejection remains a separate stack operation.

Stack contribution weights

Equal contribution retained after weighting review

Compared with an equal-weight control using the exact same exposures, crop, normalization and pixel rejection. Star width and shape are reviewed separately.

No supported texture improvement without a worse channel

Matched stars: 64 · background-texture ratio R/G/B: 1.000 / 1.000 / 1.000. Ratios compare weighted / equal; they are not a calibrated SNR.

Per-exposure weights and method

Weights are proportional to inverse background variance after Siril additive-scale normalization, independently in R, G and B, normalized to mean one. Displayed native values are reconstructed from rounded saved statistics. A weight is not a universal quality grade.

Explain this comparison

Comparison with your current archive: each physical observing session has equal weight. Valid per-exposure values are first averaged within each session, then the session means are averaged. Later sessions and the exposures shown here may be included. This is neither an independent test nor a formal quality grade.

Selected data use the exact input IDs of this product. RGB and DNB, methods, units, sampling and recorded acquisition settings remain separate. Unknown setup metadata do not establish physical compatibility. A few sessions form only a small descriptive reference. Missing values do not count as zero.

FWHM and star shape are saved medians of the stellar fits in each exposure; the display averages these per-exposure values. Stellar SNR is the saved median of model estimates from at least five stars per exposure. Model: source Poisson noise, background variance and uncertainty in the mean local sky. Circular aperture radius 3, sky annulus 5–7 sampling pixels, 3σ clipping. EGAIN in electrons/ADU is required. Different star selections remain a limitation even within the same field.

Background and scatter are raw green-grid ADU under compatible acquisition conditions. Field emission, gradients and stellar populations limit comparison. These are not measurements of pure seeing, nebular SNR or transit sensitivity. The previous grading rule requiring eight other nights has not changed.

Method, coverage and limitations

Review distance = (value − session median) / (1.4826 × MAD). The threshold 3.5 is an advisory rule, not statistical significance. At least 12 valid frames and 75% coverage are required; zero MAD is unavailable. SNR requires the existing gain and star-count checks. Background changes are flagged in either direction.

Shared tracking/focus problems can affect an entire night without producing an outlier. No independent validation labels exist yet. Raw-green sampling and changing star populations limit interpretation. RGB/DNB, exposure, method and recorded orientation remain separate; unknown metadata do not establish compatibility.

RGB · 30.0 s · session acq_49161a3a: Background level 184/184; Background scatter 184/184; Detected sources 0/184: too few valid session frames; Star eccentricity 184/184; Star width (FWHM) 184/184; Stellar SNR estimate 184/184. Unknown: device_id, filter, optical_configuration, readout_mode, recorded_orientation_deg.
