Detect the IAU constellation of each meteor trail endpoint - #5
Merged
Conversation
Identify which constellation the trail started and ended in, derived from the
parsed equatorial coordinates, and surface it in the sky view.
Backend:
- constellation.py: Roman (1987) point-in-constellation lookup; precesses the
J2000 position to B1875 (closed-form IAU-1976, dependency-free) and matches
the bundled IAU boundary table (VizieR VI/42).
- ParsedMeasurement gains start/end_constellation (migration 0003);
PARSE_VERSION 1 -> 2 so existing rows re-derive lazily.
- /v1/web/reports/{key} returns constellation per trail endpoint.
Frontend:
- Sky caption shows "v souhvězdí <Name>" / "in <Name>", localized from the
already-loaded constellation data; refreshed via onSkyData once names load.
