public class EclipticProvider extends Object implements TransformProvider
The IAU defines the ecliptic as "the plane perpendicular to the mean heliocentric
orbital angular momentum vector of the Earth-Moon barycentre in the BCRS (IAU 2006
Resolution B1)." The +z axis is aligned with the angular momentum vector, and the +x
axis is aligned with +x axis of MOD
.
This implementation agrees with the JPL 406 ephemerides to within 0.5 arc seconds.
