Solar System Primary Ephemeris Tuesday, March 10th 2009
This Ephemeris record the position and velocity vectors of Sun, all planets in Solar System and Pluto for June 28th 1969. The information required for making this ephemeris was taken from JPL NASA.
The starting conditions for DE405/LE405 were the result of two successive least-squares adjustments. The first adjustment was a solution for all of the relevant parameters whose values were best determined from the ephemeris data. Then, some of the parameters were rounded off (at a negligible level) for the sake of appearance and ease of use. These rounded values were then forced as known constants into the second solution which produced a minor adjustment to the other parameters.
