| Description: ring_event_tdb indicates the instant at which photons associated with a particular ring observation left the ring plane. This time is earlier than the associated observed_event_tbd by an amount equal to the light travel time. ring_event_tdb is represented 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. One of ring_event_time or ring_event_tdb is a required table field for all ring occultations. Both may be used. |
