PHYSICAL EPHEMERIDES : CALCULATED PARAMETERSThe ephemerides for the physical observation of the solar system bodies are calculated in a geocentric equatorial reference of which the reference plan is the plan of the true terrestrial equator and the origin is in the direction of the equinox of the date. The scale of time of calculations is Terrestrial Time. The calculated parameters are:

http://www.imcce.fr/public/images/site/puce_carre.gifSSPSub Solar Point planetocentric longitude and latitude (Sub Solar Point)Point)(**)
http://www.imcce.fr/public/images/site/puce_carre.gifNPAngle of position of the planet North Pole compared to the direction of the celestial North Pole (in degree)
http://www.imcce.fr/public/images/site/puce_carre.gifd poleDistance between the center of planet and its North Pole or southern (in second of degree or minute of degree for the Moon)
http://www.imcce.fr/public/images/site/puce_carre.gifMvVisual magnitude
http://www.imcce.fr/public/images/site/puce_carre.gifPhasePhase angle (in degree)
http://www.imcce.fr/public/images/site/puce_carre.gifR.AppApparent radius of the body (in second of degree or minute of degree for the Moon)
http://www.imcce.fr/public/images/site/puce_carre.gifDgEarth-body distance (in astronomical Unit or terrestrial unit of radius for the Moon)
http://www.imcce.fr/public/images/site/puce_carre.gifDhSun-body distance (in astronomical Unit)
http://www.imcce.fr/public/images/site/puce_carre.gifPAQAngle of position of the intensity equator (in degree)
http://www.imcce.fr/public/images/site/puce_carre.gifQLength of the right-side segment on the equator of intensity which is not illuminated (on the surface of the apparent disc of planet, in second of degree or minute of degree for the Moon)
and according to the case :

http://www.imcce.fr/public/images/site/puce_carre.gifLambda, BetaBody ecliptic longitude and latitude (geocentric reference; true ecliptic; equinox of the date)
http://www.imcce.fr/public/images/site/puce_carre.gifX, Y, ZRectangular coordinates of the body (in astronomical Unit) (geocentric reference; true equator; equinox of the date)
