A8.5 Glossary
| Cartesian State | Cartesian position and velocity components in the following order: x-position, y-position, z-position, x-velocity, y-velocity, and z-velocity. |
| Equinox | Vernal equinox. For the planets, the vernal equinox is defined as the axis from the center of the planet to the ascending node of the planet’s orbit through the planet’s equatorial plane. |
| Jupiter System I | This prime meridian system is identified with the Prime Meridian rotation of the visible features in the Jovian equatorial zone. The exact definition of this system can be found in the Explanatory Supplement to the Astronomical Ephemeris and The American Ephemeris and Nautical Almanac (Explanatory Supplement to the Ephemeris). JPL Technical Report (TR) 32-12508, dated January 15, 1971. |
| Jupiter System III | This prime meridian system is identified with the Prime Meridian rotation of radio emissions from Jupiter. This rotation probably corresponds to the rotation of the Jovian inner core which is associated with the planet’s magnetic field. The SEDR uses Jupiter System III (1965.0). |
| Longitude | The longitude convention will conform to the IAU standards which specify positive west longitudes for Jupiter. |
