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.

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.

Timing, uncertainty and applicability

Not calibrated standard magnitudes. Native G1+G2 response/Flat/pixel-phase and shared errors remain unbounded.
Recorded header start times support relative intervals; TIMESYS and clock accuracy are not established. No BJD_TDB.
References exclude each target but share sky/calibration systematics. Conditional errors hold median normalizations fixed.
No new search is run here. Existing event evidence and eligibility are retained; review scores are not calibrated false-alarm probabilities.
No new aperture is promoted. Mixed exposures, passbands, nights and calibration/angle segments stay separate.

Insufficient contiguous data or independent references for the blocked comparison.

2 contiguous blocks are too short; no test is forced across the gap.

Scientific baseline retained. No promotion from scatter alone; independent control observations and a calibrated uncertainty model are still required.

Validation design and limits

Four contiguous held-out folds per sufficiently long uninterrupted block, with one purged epoch on each side. Reference medians are learned only from training epochs; each target is excluded from its references. Fixed Huber cutoff 1.5, at least six references. No hyperparameter search or target-based refitting.

Blocked epoch checks within existing calibration/orientation segments, not independent new-night validation.
Stars share references and are not independent trials; no p-values or discovery probability are inferred.
Lower scatter may remove reference contamination but does not prove better physical accuracy.
Existing shared-master, flat, centroid, sampling and clock uncertainties remain unresolved.
Artificial dimming checks algebraic signal transfer only, not transit detection or recovery efficiency.
No re-fitting, smoothing or interpolation of target flux; gaps and unavailable measurements remain gaps.

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.

Timing, uncertainty and applicability

Not calibrated standard magnitudes. Native G1+G2 response/Flat/pixel-phase and shared errors remain unbounded.
Recorded header start times support relative intervals; TIMESYS and clock accuracy are not established. No BJD_TDB.
References exclude each target but share sky/calibration systematics. Conditional errors hold median normalizations fixed.
No new search is run here. Existing event evidence and eligibility are retained; review scores are not calibrated false-alarm probabilities.
No new aperture is promoted. Mixed exposures, passbands, nights and calibration/angle segments stay separate.

Comparison-star robustness check

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.

RGB · 180.0 s · 0 supported source/segment tests

Insufficient contiguous data or independent references for the blocked comparison.

4 contiguous blocks are too short; no test is forced across the gap.

3 contiguous blocks are too short; no test is forced across the gap.

Scientific baseline retained. No promotion from scatter alone; independent control observations and a calibrated uncertainty model are still required.

Validation design and limits

Blocked epoch checks within existing calibration/orientation segments, not independent new-night validation.
Stars share references and are not independent trials; no p-values or discovery probability are inferred.
Lower scatter may remove reference contamination but does not prove better physical accuracy.
Existing shared-master, flat, centroid, sampling and clock uncertainties remain unresolved.
Artificial dimming checks algebraic signal transfer only, not transit detection or recovery efficiency.
No re-fitting, smoothing or interpolation of target flux; gaps and unavailable measurements remain gaps.
