The source epoch and its original time system are preserved. Approximate alternate times are labeled derived and are not presented with synthetic sub-day precision.

Separation and P.A. values calculated from published RA/Dec offsets are labeled derived and rounded for display. CSV/JSON and fitter downloads retain the native coordinates and covariance when available.

Near-identical rows repeated by later compilation papers are collapsed in favor of the original measurement-paper citation. Position angle is east of north.
