Parameter | Units | Description |
---|---|---|
| degrees | equatorial right ascension ( |
| degrees | apparent geocentric ecliptic longitude ( |
| degrees | Moon's argument of latitude: the mean distance of the Moon from its ascending node |
| none | Time stamp in dynamical time, i.e. adjusted for |
| degrees | geocentric ecliptic longitude ( |
| degrees | parallax that varies with the rotation of the Earth or with a difference in location on the Earth; typically only significant for the Moon |
| none | Julian Ephemeris Day, i.e. Julian Day adjusted for |
| degrees | mean anomaly of the Moon |
| degrees | mean anomaly of the Sun |
| degrees | The Moon's instantaneous angular distance east of the Sun |
| degrees | nutation in ecliptic longitude |
| degrees | nutation in obliquity of the ecliptic |
| degrees | obliquity of the ecliptic: the inclination of Earth's equator with respect to the ecliptic |
| au (sun), km (moon) | distance from body to Earth, measured between centers |
