ring_profile_direction in Occultation_​Ring_​Profile

Name: ring_profile_directionVersion Id: 1.0.0.0
Description: ring_profile_direction indicates the radial direction of a ring occultation within a particular data product. Possible values are 'Ingress', 'Egress', or 'Multiple'. The value 'Multiple' is used where the occultation track is not monotonic over relatively short time scales. Generally only used for some Hubble-based occultations. May be appropriate for extremely long duration occultations of a high proper motion star (e.g., u36). Required in labels of ring occultation observations. Not intended as a value for a table field.

 EgressThe ring radius along the occultation track increases with time.
 IngressThe ring radius along the occultation track decreases with time.
 MultipleThe occultation track is not monotonic over relatively short time scales. Generally only used for some Hubble-based occultations. May be appropriate for extremely long duration occultations of a high proper motion star (e.g., u36).
