Summary of siding_spring_s46 made using the SPICE "brief" utility. Note that comet siding spring has not yet been entered into the NAIF Toolkit code that associates a name with a SPICE ID. Thus, to use this SPK file one must use *ONLY* the Siding Spring ID, which is 1003228.

This is because an object's orbit solution may be insufficiently determined over the chosen time-span to be suitable for some high-precision purposes, due to the quantity of measurements available for an object, the time-span they cover, and the object's dynamical path. Although not stored in this file, statistical uncertainty of the trajectory as a function of time may be available from the JPL Horizons system. This can help interpret the accuracy of the trajectory. Orbit solutions are updated in Horizons as new measurements are made, so this trajectory may be superceded by more recent solutions. Check the orbit solution number for an object (given below as "source") against the latest Horizons entry to determine if an updated orbit solution is available.
