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:

	登录/注册后可看大图   SEP	Sub Earth point planetocentric longitude and latitude of the (Sub Earth Point)(*)
	登录/注册后可看大图   SSP	Sub Solar Point planetocentric longitude and latitude (Sub Solar Point)Point)(**)
	登录/注册后可看大图   NP	Angle of position of the planet North Pole compared to the direction of the celestial North Pole (in degree)
	登录/注册后可看大图   d pole	Distance between the center of planet and its North Pole or southern (in second of degree or minute of degree for the Moon)
	登录/注册后可看大图   Mv	Visual magnitude
	登录/注册后可看大图   Phase	Phase angle (in degree)
	登录/注册后可看大图   R.App	Apparent radius of the body (in second of degree or minute of degree for the Moon)
	登录/注册后可看大图   Dg	Earth-body distance (in astronomical Unit or terrestrial unit of radius for the Moon)
	登录/注册后可看大图   Dh	Sun-body distance (in astronomical Unit)
	登录/注册后可看大图   PAQ	Angle of position of the intensity equator (in degree)
	登录/注册后可看大图   Q	Length 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 :

	登录/注册后可看大图   RA, DEC	Right ascension and variation of the body (geocentric reference; true equator; equinox of the date)
	登录/注册后可看大图   Lambda, Beta	Body ecliptic longitude and latitude (geocentric reference; true ecliptic; equinox of the date)
	登录/注册后可看大图   X, Y, Z	Rectangular coordinates of the body (in astronomical Unit) (geocentric reference; true equator; equinox of the date)

不是客气，我真没看懂

形同天书

莫非LZ准备登月?

哦，原来是这样。。。。。

不会美国鸡肠，还望零度写中文。
