fun geoEmbState(time: Time): StateVector
Calculates the geocentric position and velocity of the Earth/Moon barycenter.
Given a time of observation, calculates the geocentric position and velocity vectors of the Earth/Moon barycenter (EMB). The position (x, y, z) components are expressed in AU (astronomical units). The velocity (vx, vy, vz) components are expressed in AU/day.
The EMB's position and velocity vectors in geocentric J2000 equatorial coordinates.
