Catalogue information from SIMBAD/CDS. Labels are reference positions, not new detections or measured object boundaries.
495 saved star coordinates reproduced. Reproduction of a previously validated mapping; not an independent solve or new positional measurement. Existing reference residual (95%): 1.59 pixels. This is not a precision estimate for diffuse-object centres.
Markers denote catalogue reference positions, not measured detections, extents or abundances. Diffuse objects can have approximate catalogue positions; centre-outside does not mean all emission is outside. WCS header FK5; inherited empirical Gaia/ICRS numerical convention retained after refinement. Inspection zoom windows are viewing aids, not physical object boundaries.

Verified video for this exact saved image; depth is an illustrative display effect.
Saved per-exposure measurements; no universal quality score.
272 of 272 selected input exposures have cached histograms.
Measured curves in 4 of 6 saved image groups. Measurement availability does not establish a transit or a calibrated detection significance.
Each module is checked separately. An unavailable module does not invalidate the saved master; a complete list is not scientific certification.

Selected input exposures
Selected inputs against your whole archive · RGB and DNB remain separate.
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.

Provisional star fits · stellar SNR is a model estimate, not master SNR.
Provisional stellar models: undersampled stars can bias the measurements. Differences are not quality grades. Stellar SNR is not nebular or master-image SNR.
A reliable improvement has not been established. The previous selected image is retained.
381 → 422 unique Lights · 12 h 05 min 30 s → 14 h 08 min 30 s
64 matched stars out of 64 prior-master comparison stars · 975 common low-intensity regions.
The same valid image area, stellar brightness scale and saved linear data are compared. The comparison stars are selected using the prior master only; missing or unmeasurable counterparts count against coverage and are not replaced. A noise/SNR proxy above 1 indicates less fine-scale background texture at matched stellar flux. It is not an absolute master SNR. Stellar width is checked for degradation; it is not a measurement of optical resolution. These masters share exposures, so no independent-sample significance is claimed. Gradients and correlated noise can still affect this engineering check.
A newer qualified finished master is not yet available. The previous selected master is retained.

Planning · model estimate
Based on the actual inputs of this selected master. RGB and DNB are modelled separately.
Current relative SNR = 1.00×. This is a reference level, not a measured master SNR. There is no universal “good” SNR target: it depends on the feature, aperture or region, noise definition and intended use.
11 h 11 min · 272 selected Lights. Sub-exposures: 120 s, 180 s, 300 s
One more comparable hour: about 4.4% higher SNR relative to now. Each following hour adds less relative benefit; it does not become useless.
| Relative SNR goal | Additional time | Total time |
|---|---|---|
| 1.25× | 6 h 17 min 26 s | 17 h 28 min 26 s |
| 1.50× | 13 h 58 min 45 s | 25 h 09 min 45 s |
| 2.00× | 33 h 33 min | 44 h 44 min |
Detail visibility is not angular resolution. More integration can reveal fainter structures. Seeing, optics, sampling, focus and guiding limit sharpness; this curve does not predict smaller or rounder stars.
Same target region, filter, camera, sub-exposure mix, throughput and sky conditions; independent random noise and comparable stacking weights. Fixed-pattern noise, calibration errors, gradients, correlated noise, changing conditions and rejected data can reduce the realised gain. Total exposure is not an effective per-pixel weight or an HDR-core coverage map.
Relative SNR = √((current time + additional time) / current time). Required extra time = current time × (goal² − 1). No numerical floor or absolute master SNR has been fitted; no per-frame star-SNR median is substituted.
Time means usable integration in the stack, excluding overheads, rejected frames and nights with unsuitable conditions. The curve is a planning scenario, not a measured progress history.

Saved time assumptions are unchanged. Site and weather are shown on the session pages.
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.

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.

Selected input exposures
Selected inputs against your whole archive · RGB and DNB remain separate.
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.

1.4826 × median absolute deviation divided by median. Nonoverlapping bins never split an exposure; boundary crossings remain in the native curve. Sparse bins do not establish a precision improvement.
Recommended next acquisition: characterize unsaturated stars with matched short-exposure Darks and same-session Flats, then keep one exposure/filter configuration through a dedicated known-host event and its before/after baseline. There is no real 60/120 s improvement demonstrated here.
Could a more robust reference ensemble improve these light curves? This controlled experiment reuses the original native fluxes. Your published scientific curves and event results remain unchanged.

2026-10-16 · RGB · Gaia 369152439091358592. First available session and source ID; not selected for apparent variability.
1 excluded from this imaging stack · 2 flagged for inspection · 42 original exposures retained.
Exclusions affect this image stack only. Raw measurements and calibrated scientific images remain available. A satellite-like line alone does not reject an entire exposure.
Jointly broader and more elongated than this session; possible shake/tracking/focus effects, cause not established.
Measurement differs from its session. Retained: this alone does not establish a defective exposure.
Relative stack weights (R/G/B): 0.786 / 0.840 / 0.808
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.

Native noise weighting used
Compared with an equal-weight control using the exact same exposures, crop, normalization and pixel rejection. Star width and shape are reviewed separately.
Matched stars: 64 · background-texture ratio R/G/B: 0.979 / 0.986 / 0.986. Ratios compare weighted / equal; they are not a calibrated SNR.
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.

Saved time assumptions are unchanged. Site and weather are shown on the session pages.
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.

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.
