就是在特定时间的月球在地心惯性坐标系中的位置矢量和速度矢量。先谢了。

你的网名很不错啊.

已经把JPL搞到手了.

XYZ坐标分量,及VX、VY、VZ速度三分量

太谢谢了。LS是学生还是工作了，干哪行的？

楼主要找天文上的高人？

请与xjw01、ldlcau等朋友联系。

他们都有能力自己编星历表。

 

我只不过一个爱好者而已。

这里高人不少。

还有一个问题，表中给出的是地心黄道惯性坐标系中的数据，能不能直接查到地心赤道惯性坐标系的数据。刚才试着查了一下没有查到。

Table Settings

Optional vector-table settings:

output units :	AU & AU/d km & km/d km & km/s -- units for most output quantities
quantities code :	1 (position components {x,y,z} only) 2 (state vector {x,y,z,vx,vy,vz}) 3 (state vector, 1-way light-time, range, and range-rate) 4 (position, 1-way light-time, range, and range-rate) 5 (velocity components {vx,vy,vz} only) 6 (1-way light-time, range, and range-rate) -- selection of vector output quantities
reference plane :	ecliptic and mean equinox of reference epoch Earth mean equator and equinox of reference epoch body mean equator and node of date -- reference plane for all output quantities
reference system :	ICRF/J2000.0 FK4/B1950.0 -- reference frame for geometric and astrometric quantities
correction :	NONE (geometric states) LT (astrometric states) LT+S (astrometric states corrected for stellar aberration) -- selects level of correction to output vectors
labels :	-- enable labeling of each vector component
CSV format :	-- output data in Comma-Separated-Variables (CSV) format
object page :	-- include object information/data page on output

 

reference plane :

ecliptic and mean equinox of reference epoch Earth mean equator and equinox of reference epoch body mean equator and node of date

这一项选这个参数,你看看是不是你所要的赤道数据?

 

reference plane :

ecliptic and mean equinox of reference epoch Earth mean equator and equinox of reference epoch body mean equator and node of date

选这个是黄道数据.

 

reference plane :

ecliptic and mean equinox of reference epoch Earth mean equator and equinox of reference epoch body mean equator and node of date

还有这个,我也不懂具体用哪个了.

请其他高人来回答吧.

 

好的，谢谢。我好好研究一下。
