| Description: The geometry reference time given in the 'Barycentric Dynamical Time' system, as a number of elapsed seconds since the J2000 epoch. This is consistent with the definition of 'ephemeris time' as used in the SPICE toolkit. The value must correspond to the time specified in the geometry_reference_time_utc attribute. |
