This attribute sets the values for Target Vector Outgoing Asymptote elements used to define the spacecraft's Initial State.
Astrogator <Satellite Object Path> SetValue <Astrogator Object Path>.Target_Vector_Outgoing_Asymptote.{Element} <Value> <Unit>
If you select Target Vector Outgoing Asymptote as the Coordinate Type, the elements to be specified are the same as those for the Target Vector Incoming Asymptote type, except that Right Ascension and Declination are defined in terms of the outgoing rather than the incoming asymptote.
