pub fn spherical(t: f64, tol: f64) -> (f64, f64, f64, f64, f64, f64)Expand description
Calculate geocentric spherical coordinates of the Moon. The frame is dynamical
equinox and ecliptic J2000. The time scale of t is TDB. To speed up, we ignore
terms whose cmpb or cper are smaller than tol.
§Return
- out.0: longitude (rad)
- out.1: latitude (rad)
- out.2: distance (km)
- out.3: longitude’ (rad/day)
- out.4: latitude’ (rad/day)
- out.5: distance’ (km/day)
