Calculates jovicentric positions and velocities of Jupiter's largest 4 moons.
Calculates position and velocity vectors for Jupiter's moons
Io, Europa, Ganymede, and Callisto, at the given date and time.
The vectors are jovicentric (relative to the center of Jupiter).
Their orientation is the Earth's equatorial system at the J2000 epoch (EQJ).
The position components are expressed in astronomical units (AU), and the
velocity components are in AU/day.
To convert to heliocentric vectors, call HelioVector
with Astronomy.Body.Jupiter to get Jupiter's heliocentric position, then
add the jovicentric vectors. Likewise, you can call GeoVector
to convert to geocentric vectors.
