Functions
auto	astro::earth::precession::equatorial_angles (const double jde_from, const double jde_to) -> EquatorialAngles
	Compute the equatorial precession angles ζ, z, θ between two epochs.
auto	astro::earth::precession::equatorial (const toolbox::AngleDeg &α0, const toolbox::AngleDeg &δ0, const double jde_from, const double jde_to) -> astro::coords::EquatorialCoord
	Apply equatorial precession, carrying (α₀, δ₀) from one epoch to another.
auto	astro::earth::precession::ecliptic_angles (const double jde_from, const double jde_to) -> EclipticAngles
	Compute the ecliptic precession quantities η, Π, p between two epochs.
auto	astro::earth::precession::ecliptic (const toolbox::AngleDeg &λ0, const toolbox::AngleDeg &β0, const double jde_from, const double jde_to) -> astro::coords::EclipticCoord
	Apply ecliptic precession, carrying (λ₀, β₀) from one epoch to another.
