How can I use the OT to observe ephemeris objects?

Authors list

Solar system bodies which are not included in the "Choose a Solar System object?" drop-down list in the Field Setup section of a Science Goal can be specified using the 'Ephemeris' option in the same list. This lets you load a JPL Horizons file as the ephemeris. Please see the 'Create an External Ephemeris' section of the OT User Manual available from the Science Portal under 'Documents & Tools' for more details on the exact format to be used.
