IMPORTANT: ------------------------------------------------------------------------------- This informal file release should not be used for "category A" flight project purposes (involving the safety and success of spacecraft hardware and mission) without first contacting Donald.K.Yeomans@jpl.nasa.gov (Supervisor, Solar System Dynamics Group, 818-354-2127). That is, this particular object's orbit may be insufficiently well-determined, over the chosen time-span, to be suitable for some high-precision purposes.
