Figure D-1. Earth Mean Ecliptic and Equinox of 1950.0 (ECL50), Cruise SEDR State Vectors

Nomenclature --> S refers to State Vector (position and velocity components) with the subscripts AB, where A is the reference or "from" body and B is the "to" body. The following body definitions are used: S - Sun; P - S/C or Probe; E - Earth; 5 - Jupiter; and 6 - Saturn.

Note that the Earth State with respect to Jupiter and Saturn (S_5E and S_6E - dashed vectors in figure) will not be provided. These states can be simply derived, if desired, by the PI by vector subtraction of the Sun to Earth State (S_SE) and the Sun to Jupiter and the Sun to Saturn States (S_S5 and S_S6).
