Birth atlas preview: selected star data and line patterns

Stellar positions: XHIP, Anderson & Francis (2012), VizieR V/137D.
J2000 coordinates and magnitudes distributed in d3-celestial stars.8.json.

Retrieved 2026-10-24. Selected 340 HIP stars, without changing their source positions.

Chinese individual-star names: d3-celestial starnames.cn.json, derived from
Stellarium's Chinese sky-culture naming material, matched by HIP identifier.

Retrieved 2026-10-25. Original Chinese names are retained, not translated
from their English glosses. Naming provenance and CC BY-SA attribution retained.

Our adaptation selects 54 groups, retains source HIP paths, projects them to
three equatorial sheets and one polar inset, and omits edges at sheet boundaries.
This adapted line-pattern dataset is shared under CC BY-SA as well.
These are modern Chinese-sky identification patterns, not a reconstruction of
the Dunhuang manuscript or evidence for an astrological interpretation.
