attribute definition:
radial_resolution
radial_resolution indicates the nominal radial distance over which changes in ring properties can be detected within a data product. Note: this value may be larger than the radial_sampling_interval value, because a data product can be over-sampled. Required in labels if the value is fixed, as it is for stellar occultations. If the value varies, the corresponding minimum and maximum attributes must be used instead. Not intended to be used as a table field. -

attribute definition:
type
The type attribute classifies units of storage according to the quantity being measured (storage). -

The local_identifier attribute provides a character string which uniquely identifies the containing object within the label. -
attribute definition:
comment
The comment attribute is a character string expressing one or more remarks or thoughts relevant to the object. -
attribute definition:
sclk_stop_time
sclk_stop_time is the value of the spacecraft clock corresponding to the stop_date_time given in the label. -
attribute definition:
frame_rate
The frame_rate attribute indicates the number of still pictures (or frames) that should be displayed per unit of time in a video. Note this is NOT necessarily the same as the rate at which the images were acquired. -
attribute definition:
data_set_terse_desc
A one line description of the data set -
attribute definition:
medium_type
The medium_type attribute identifies the physical storage medium for a data volume. Examples: CD-ROM, CARTRIDGE TAPE. -
attribute definition:
lidvid_reference
The lidvid_reference attribute provides the logical_identifier plus version_id, which uniquely identifies a product. -
attribute definition:
minimum_value
The minimum_value attribute provides the lower inclusive bound on the value. -
attribute definition:
character_constraint
The character_constraint attribute limits the characters allowed. -
attribute definition:
steward_id
The steward_id attribute provides the abbreviation of the organization that manages the set of registered attributes and classes. -
attribute definition:
character_constraint
The character_constraint attribute limits the characters allowed. -
attribute definition:
minimum_observed_ring_elevation
minimum_observed_ring_elevation specifes the smallest value for observed_ring_elevation in the data file. Only used if the value is not constant over the observation. Values range from -90 to +90 in units of degrees. Not intended for use in the data file. -
attribute definition:
unit_id
The unit_id attribute provides a character or character string which serves as an abbreviation for, or symbol representing, a unit of measure. -
attribute definition:
field_format
The field_format attribute gives the magnitude and precision of the data value. A subset of the standard POSIX string formats is allowed. See the PDS Standards Reference section "Field Formats" for details. -
attribute definition:
name
The name attribute provides a word or combination of words by which the object is known. -
attribute definition:
type
The type attribute provides a classification for the resource. -
attribute definition:
standard_deviation
The standard_deviation attribute provides the standard deviation of values in the associated object; empty and Special_Constants values are excluded. -
attribute definition:
supported_operating_system_note
The supported operating system note attribute identifies the Operating System that supports the software. -
attribute definition:
manifest_checksum
The manifest checksum provides the checksum for the manifest file. -
attribute definition:
formation_rule
The formation_rule attribute provides a 'user friendly' instruction for forming values. -
attribute definition:
sampling_parameter_interval
The sampling_parameter_interval attribute provides the spacing of points at which data are sampled and at which values for an instrument or other parameter are available. If x1 and xn are the first and last sampling parameter values, respectively, xn is larger than x1, n is the number of sampling parameters, the caret symbol (^) denotes exponentiation, and b, a positive real number, is the base for exponentiation, then the value of sampling_parameter_interval is: (xn-x1)/(n-1) (for sampling_parameter_scale = Linear), (xn/x1)^(1/(n-1)) (for sampling_parameter_scale = Logarithmic), (b^xn-b^x1)/(n-1) (for sampling_parameter_scale = Exponential). -
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. -
