Functions
template<astro::vsop87d::Planet planet>
auto	heliocentric (const double jde_tt) -> toolbox::SphericalCoordinate
	Evaluate VSOP87D at JDE(TT), returning heliocentric mean-ecliptic-of-date angles and AU radius.
template<Planet target, astro::vsop87d::Planet model>
consteval auto	make_vsop87d_mapping () -> Vsop87dMapping
	Bind one planetary identity to its VSOP87D evaluator at compile time.
auto	heliocentric (const Planet planet, const double retarded_jde_tt, const double observation_jde_tt) -> toolbox::SphericalCoordinate
	Evaluate at emission time and express the direction in mean observation-date ecliptic axes.
auto	rectangular (const toolbox::SphericalCoordinate &spherical) -> RectangularCoordinate
	Convert to Cartesian AU in the input's unchanged origin and axes.
auto	light_time_corrected (const Planet planet, const double jde_tt, const toolbox::SphericalCoordinate &earth) -> toolbox::SphericalCoordinate
auto	aberration (const double jde_tt, const toolbox::SphericalCoordinate &coordinate, const toolbox::SphericalCoordinate &earth) -> AberrationCorrection
auto	validate_input (const Planet planet, const double jde_tt) -> std::string_view
	Validate finite JDE(TT) before planet identity, returning the name for error context.
auto	validate_apparent_input (const Planet planet, const double jde_tt) -> std::string_view
	Apply finite-time and identity checks, then Pluto's half-open apparent-position window.
auto	validate_retrograde_input (const Planet planet, const double jde_tt) -> void
	Validate a centered one-day direction test, reserving both endpoints in Pluto's window.

heliocentric() [1/2]

template<astro::vsop87d::Planet planet>

auto astro::planet::detail::heliocentric ( const double jde_tt ) ->toolbox::SphericalCoordinate

inlinenodiscard

Evaluate VSOP87D at JDE(TT), returning heliocentric mean-ecliptic-of-date angles and AU radius.

heliocentric() [2/2]

auto astro::planet::detail::heliocentric ( const Planet planet, const double retarded_jde_tt, const double observation_jde_tt )->toolbox::SphericalCoordinate

inlinenodiscard

Evaluate at emission time and express the direction in mean observation-date ecliptic axes.

Note

VSOP87D uses astro::earth::precession::ecliptic; Pluto uses pluto::heliocentric_for_subtraction. Both return the unmodified heliocentric radius for subtraction from observation-time Earth.
