| Description: ring_event_time indicates the instant at which photons associated with a particular ring observation intercepted the ring plane. This time is earlier than the associated observed_event_time by an amount equal to the light travel time. ring_event_time is a required table field for ring occultation data. The time is given in numeric seconds as an offset from the specified UTC reference time. The reference time is preferably the start of a day, and is required to be given in the label using the attribute reference_time_utc. One of ring_event_time or ring_event_tdb is a required table field for all ring occultations. One of ring_event_time or ring_event_tdb is a required table field for all ring occultations. Both may be used. If ring_event_time is used, the attribute reference_time_utc is required in the label. |
