Obliquity of ecliptic constants (Laskar 1986 formula)
These constants are used to calculate the obliquity of the ecliptic
(the angle between the ecliptic and celestial equator) as a function of time.
Formula: ε₀ = C0 + C1T + C2T² + C3*T³
where T = Julian Centuries from J2000.0

using the results of general theory", Astronomy and Astrophysics, 157, 59–70.
