Converting between ecliptic (β, λ) and equatorial (δ, α) coordinates requires the obliquity of the ecliptic (ε ≈ 23.44°).
(avoids cosine ambiguity for small distances): [ \texthav(z) = \texthav(\Delta\phi) + \cos(\phi_1)\cos(\phi_2)\texthav(\Delta\lambda) ] where (\texthav(\theta) = \sin^2(\theta/2)). spherical astronomy problems and solutions
