# VSOP87 planetary theory.

# Status: pending raw-file migration. The siderust crate currently embeds the
# coefficients in src/data/compiled/vsop87[ae].rs. The migration plan is to
# place the upstream IMCCE distribution files in raw/ alongside this manifest
# and rebuild the embedded tables (or a tiny on-disk binary) from them.
