Gaia DR3
Legacy/superseded pipeline record retained for methodology and archive context. Historical candidate counts and classifications are unreconciled, are not current discovery results, and do not provide evidence for a bounce.
Key findings
01 Historical, unreconciled pipeline output — 500 anomalies from 50K sources (1% top-cut)
02 Historical, unreconciled pipeline output — Cross-validation stability 41% — training-sample-conditioned
03 Historical, unreconciled pipeline output — 22 features including period, amplitude, Stetson J, chi-squared
04 Historical, unreconciled pipeline output — Extreme variable stars, high proper motion objects
05 Historical, unreconciled pipeline output — Exploratory tier only — dedicated Gaia-optimized detector needed
