Review controls
- Coordinate source
- Historical (Sternberg Astronomical Institute) public coordinates
- Uncertainty
- Published or catalogued coordinate, rounded for public display
- Release state
- Resolved reference case
- Marker use
- resolved quasar comparison coordinate
Processing notes
- source publication review
- coordinate normalization for Night Watch where available
- classification against FAL behavioral taxonomy
- retention as a public comparison case
Ordinary-source checks
- source interpretation retained from the cited literature
- public summary avoids unsupported origin claims
- comparison use is behavioral rather than evidentiary
Release limits
- interpretation remains with the cited source record
- FAL classification is behavioral and does not replace the original literature
- coordinates are shown only when stable public values are available
