The minimum_characters attribute provides the lower, inclusive bound on the number of characters. -
attribute definition:
rotation_direction
The rotation_direction element provides the direction of rotation as viewed from the north pole of the 'invariable plane of the solar system', which is the plane passing through the center of mass of the solar system and perpendicular to the angular momentum vector of the solar system. The value for this element is PROGRADE for counter -clockwise rotation, RETROGRADE for clockwise rotation and SYNCHRONOUS for satellites which are tidally locked with the primary. Sidereal_rotation_period and rotation_direction_type are unknown for a number of satellites, and are not applicable (N/A) for satellites which are tumbling. -

attribute definition:
description
The description attribute provides a statement, picture in words, or account that describes or is otherwise relevant to the object. -
attribute definition:
mean
The mean attribute provides the sum of the stored field values divided by the number of values in all records (empty fields and Special_Constants values are excluded from both the sum and the count). -
attribute definition:
ring_profile_direction
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 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:
reference_time_utc
reference_time_utc provides a date and time in UTC format. Given in a label when time values in a table are given as elapsed seconds offset from a reference time. Unless there are compelling reasons to do otherwise, reference_time_utc should correspond to the start of a day. Required anytime a table field is given relative to a specific date and time other than when Barycentric Dynamical Time is used (e.g., observed_event_tdb). -
attribute definition:
pattern

attribute definition:
character_encoding
The character_encoding attribute identifies the standard that maps a set of allowed characters to their machine readable code. -
attribute definition:
low_instrument_saturation
The low_instrument_saturation attribute specifies a special value whose presence indicates the measuring instrument was saturated at the low end. The value must be less than the value of the valid_minimum attribute. Values of this attribute should be represented in the same data_type as the elements in the object with which the Special_Constants class is associated. -
attribute definition:
type
The type attribute classifies units of spectral irradiance according to the quantity being measured (spectral irradiance). -
attribute definition:
maximum_characters
The maximum_characters attribute provides the upper, inclusive bound on the number of characters. -
attribute definition:
spacecraft_event_start_time_utc
spacecraft_event_start_time_utc gives the UTC time corresponding to the earliest time given by spacecraft_event_time in the data table. However, while spacecraft_event_time is given as seconds offset from a reference time, spacecraft_event_start_time_utc is given as a UTC date time. Required in the label for radio occultation data. Not used for stellar occultations. -
attribute definition:
stop_bit_location
The stop_bit_location attribute provides the position of the last bit in a bit field relative to the first bit in the parent packed data field. Bytes are sequential and bits are numbered continuously across byte boundaries within a single bit field. The first bit position in the packed data field is "1". -
attribute definition:
version_id
The version_id attribute provides the version of the product, expressed in the PDS [m.n] notation. -
attribute definition:
system_requirements_note
The system requirements note attribute identifies what is necessary to process the software. -
attribute definition:
version_id
The version_id attribute provides the version of the product, expressed in the PDS [m.n] notation. -
attribute definition:
wavelength_range
The wavelength range attribute specifies the wavelength range over which the data were collected or which otherwise characterizes the observation(s). Boundaries are vague, and there is overlap. -
attribute definition:
parsing_standard_id
The parsing_standard_id attribute provides the formal name of a standard used for the structure of a Parsable Byte Stream digital object. -
attribute definition:
sampling_parameter_interval
sampling_parameter_interval specifies the spacing of points at which data are sampled and at which a value for an instrument or dataset parameter is available. Used in labels for radio occultation supplemental files. Nillable in which case the nil_reason should be 'inapplicable'. -

attribute definition:
value

attribute definition:
minimum_characters
The minimum_characters attribute provides the lower, inclusive bound on the number of characters. -
attribute definition:
xml_schema_base_type
The xml schema base type attribute provides the data type needed for the XML schema implementation. -
attribute definition:
id_reference_to
The id_reference_to provides the identifier of the ending object in a one directional relationship. -
attribute definition:
along_track_timing_offset
along_track_timing_offset is a timing offset to the along track spacecraft position. It is the value that minimizes differences in radii of matching circular ring features observed on the ingress and egress sides of the occultation track. Optional in labels for radio occultation. Nillable in which case the nil_reason should be 'inapplicable'. -
