//! IAU 2000A and IAU 2000B nutation coefficient tables.
//!
//! ## Scientific scope
//!
//! Tabulated nutation series from the MHB2000 model, as adopted by the IAU in
//! 2000 and documented in IERS Conventions (2010), ch. 5.  The [`tables`]
//! sub-module exposes:
//!
//! * [`tables::NUT00A_LS`] — 678 luni-solar terms (IAU 2000A).
//! * [`tables::NUT00A_PL`] — 687 planetary terms (IAU 2000A).
//! * [`tables::NUT00B_LS`] — 77 luni-solar terms (IAU 2000B).
//!
//! These are the canonical, normalized Rust representation of the series
//! derived from SOFA `iauNut00a` / `iauNut00b`.  The raw provenance is
//! recorded in `nutation/manifest.toml`.
