attribute definition:
occultation_direction
occultation_direction indicates the direction of an occultation track. This refers to the observed occultation track overall, not to the subset that might appear in a particular file (e.g., if an occultation includes both ingress and egress tracks, the value for occultation_direction will be both in the data products for each occultation profile. Permitted values are 'Ingress', 'Egress', 'Both', and 'Multiple'. The value 'Multiple' is only used for some Hubble-based occultations where the occultation track is not monotonic over relatively short time scales. Required in labels of ring occultation observations. Not intended as a value for a table field. -
attribute definition:
kernel_type
The kernel_type attribute identifies the type of SPICE kernel. -
attribute definition:
instrument_desc
The instrument_desc attribute describes a given instrument. -
attribute definition:
type
The type attribute classifies units of temperature according to the quantity being measured (temperature). -
attribute definition:
sub_stellar_ring_azimuth
sub_stellar_ring_azimuth is an angle measured at a point in the ring plane, starting from the direction of a photon arriving from a star, and ending at the direction of a local radial vector. This angle is projected into the ring plane and measured in the prograde direction. Values range from 0 to 360 in units of degrees. For stellar occultation data, this angle is equal to (observed_ring_azimuth + 180) mod 360. It is available only for backward compatibility with previously published Cassini UVIS occultation data analysis; observed_ring_azimuth is the preferred quantity for archiving. sub_stellar_ring_azimuth is an optional data table field for Cassini UVIS occultation data; not recommended for other occultation data. In a label, the min and max variation attributes are optional for Cassini UVIS occultation data; not recommended for other occultation data. -
attribute definition:
volume_version_id
The volume_version_id attribute identifies the version of a data volume. All original volumes should use a volume_version_id of 'Version 1'. -
attribute definition:
valid_maximum
The valid_maximum attribute specifies the maximum valid value in the field or digital object with which the Special_Constants class is associated. Values above the valid_maximum have a special meaning. Values of this attribute should be represented in the same data_type as the elements in the object or field described. (Note that PDS3 had no qube-related valid_maximum values because all special constants were set below the valid_minimum.) -
