Classes
struct	astro::chart::BodyState
	Geocentric position and longitude rate in the true ecliptic and equinox of date. More...
struct	astro::chart::Snapshot
	An independent fixed-instant chart value; bodies follow the ephemeris target roster. More...

Functions
constexpr auto	astro::chart::civil_derived_tt_cutoff (const astro::delta_t::Model model) -> std::optional< double >
	Exclusive derived-TT cutoff for this civil policy, only where the selected model binds it.
auto	astro::chart::detail::with_delta_t_domain_context (const astro::delta_t::Model model, const astro::julian_day::Scale scale, const auto &convert) -> decltype(convert())
	Add model-domain context to the Algo4 forward conversion from civil UT1.
auto	astro::chart::detail::evaluate_bodies (const double jde_tt) -> decltype(Snapshot::bodies)
	Evaluate positions then rates in target-roster order at one admitted chart JDE(TT).
auto	astro::chart::resolve_civil_times (const calendar::Datetime &civil_dt, const astro::julian_day::Scale scale, const astro::delta_t::Model model=astro::delta_t::DEFAULT_MODEL) -> astro::julian_day::Times
	Resolve a civil instant under the adopted chart/civil-house admission policy.
auto	astro::chart::calculate (const calendar::Datetime &civil_dt, const astro::julian_day::Scale scale, const astro::GeoLocation &location, const astro::house::System system, const astro::delta_t::Model model=astro::delta_t::DEFAULT_MODEL) -> Snapshot
	Calculate geocentric positions, rates and house geometry at an explicitly scaled civil instant.
