POST-DR1 · ANALYSIS LOG
Results register
No DR1 result is entered here before the relevant public products and documented analysis are available.
AWAITING ANALYSIS
Each entry will name the release, pipeline, controls, significance and prediction-level verdict.
Post-release protocol
Six steps before making a claim
Freeze the archive
Preserve the dated pre-DR1 prediction text, version identifiers and candidate-selection rules before opening DR1-derived results.
Record the release
Log the exact Euclid data release, product versions, masks and calibration inputs used.
Apply standard controls
Document PSF modeling, shear calibration, photometric-redshift method, selection, completeness and masking.
Correct significance
Report effect size and significance with multiple-testing and look-elsewhere corrections.
Demand robustness
Repeat across independent pipelines, teams or sky regions; use cross-survey comparisons where the prediction requires them.
Classify the outcome
Label each result supportive, neutral or in tension—without rewriting the original prediction.
