attribute definition:
minimum_sampling_parameter
The minimum_sampling_parameter element identifies the minimum value at which a given data item was sampled. For example, a spectrum that was measured in the 0.4 to 3.5 micrometer spectral region would have a minimum_sampling_parameter value of 0.4. The sampling parameter constrained by this value is identified by the sampling_parameter_name element. Note: The unit of measure for the sampling parameter is provided by the unit element. -
attribute definition:
oblique_proj_y_axis_vector
Unit vector in the direction of the Y axis of the oblique coordinate system used in the OBLIQUE CYLINDRICAL projection, in terms of the X, Y, and Z axes of the standard body-fixed coordinate system. In each system, the X axis points from the body center toward longitude and latitude (0,0) in that system, and the Z axis to (0,90), and the Y axis completes a right-handed coordinate system. The OBLIQUE_PROJ_X/Y/Z_AXIS_VECTORS make up the rows of a rotation matrix that when multiplied on the left of a vector referenced to the standard coordinate system converts it into its equivalent in the oblique coordinate system. This rotation matrix is the product of successively applied rotations by +/- OBLIQUE_PROJ_POLE_LONGITUDE around the Z axis, 90 - OBLIQUE_PROJ_POLE_LATITUDE around the once-rotated Y axis, and OBLIQUE_PROJ_POLE_ROTATION around the twice-rotated Z axis. For the first of these rotations, a positive sign is used if the OBLIQUE_PROJ_POLE_LONGITUDE is given as an east longitude, and a negative sign if it is expressed as a west longitude. -

attribute definition:
mro:spectral_resampling_flag
The MRO:SPECTRAL_RESAMPLING_FLAG element identifies whether spectral resampling of CRISM data has occurred in sensor space. Spectral resampling is to remove differences in the wavelength scale of the data between different spatial positions across the field of view. The data are corrected for spectral scale by nearest neighbor resampling within columns to match the scale, to within 0.5 detector elements, to that of columns 260-359 for the VNIR, or columns 270-369 for the IR. OFF indicates no resampling, and ON indicates that resampling has occurred. -

attribute definition:
maximum_channel_id
The maximum_channel_id element identifies the highest channel from which data were obtained. For example, the Voyager PLS instrument reported measurements in a number of energy/charge channels. But not all channel values were reported to Earth; the maximum_channel_id element indicated the highest energy reported in the telemetry stream. -
attribute definition:
msl:software_keyword_name

The format of the value is AC### where AC is a 2-letter designation of the type of measurement made, and ### is a 3-numeral designation of the instrument command macro that was executed to acquire the data. Macro numbers are in the range 0-255. For EDRs, BI is measurement of detector bias, DF is a measurement of background including dark current and thermal background, LP is measurement of a focal plane lamp, SP is measurement of the internal integrating sphere, and SC is measurement of an external scene. TP indicates that the EDR contains any test pattern produced by instrument electronics. T1 through T7 specify the test pattern, test pattern 1 through test pattern 7. UN indicates that the EDR contains data in which housekeeping does not match the commanded instrument configuration. For an RDR, RA indicates that the file contains values in units of radiance (W m^-2 nm^-1 sr^-1). IF indicates that the file contains values in units of I/F, or radiance divided by solar flux scaled for heliocentric distance. AL indicates that the file contains values as estimated Labert albedo, which is I/F corrected for cosine of incidence angle and for atmospheric and thermal effects. SU indicates that the files contains summary parameters, unitless values derived from Lambert albedo. For an RDR or a DDR, DE indicates that the files contains derived values related to observation geometry or independently characterized properties of the scene. -
attribute definition:
source_lines
The source_lines element indicates the total number of lines in the image from which a rectangular sub-image has been derived.

For spacecraft, this description addresses the complement of instruments carried, the on-board communications and data processing equipment, the method of stabilization, the source of power and the capabilities or limitations of the spacecraft design which are related to data-taking activities. The description may be a synopsis of available mission documentation. -
attribute definition:
projection_latitude_type
For some map projections, identifies the type of latitude that is sampled in equal increments by successive image lines. These projections are sometimes known informally as 'database projections' because their simplicity and global applicability for storing data for an entire planet are of greater interest than their formal cartographic properties. The EQUIRECTANGULAR and SIMPLE CYLINDRICAL projections can exist with projection latitude types of PLANETOGRAPHIC or PLANETOCENTRIC. The SINUSOIDAL projection can exist with these latitude types and also AUTHALIC latitude (which makes the projection strictly equal-area for an ellipsoid but does not preserve the equal-distance properties of the projection for the sphere) or RECTIFYING latitude (which, with the appropriate modification of the scaling of meridians, results in a map with all the cartographic properties of the sinusoidal projection of the sphere: equal areas, equal distances on all parallels, and equal distances on the central meridian). Projections other than those just discussed are uniquely defined by their cartographic properties (e.g., there is only one conformal cylindrical projection, the MERCATOR projection) and do not require this keyword. See also KEYWORD_LATITUDE_TYPE. -
attribute definition:
periapsis_time
The PERIAPSIS_TIME element is the time, in UTC format 'YYYY-MM-DDThh:mm:ss[.fff]Z', when the spacecraft passes through periapsis on a particular orbit. Periapsis is the closest approach point of the spacecraft to the target body surface in its orbit around the target body. -

attribute definition:
mean_solar_day
The mean_solar_day element provides the average interval required for successive transits of the Sun. This is computed as if planets and satellites move in circular orbits about their primaries with periods as specified by the revolution_period element, and as if planets and satellites have spin axes which are perpendicular to their orbit planes. -
attribute definition:
minimum_ring_longitude
The minimum_ring_longitude element specifies the minimum inertial longitude of a ring area relative to the prime meridian. In planetary ring systems, the prime meridian is the ascending node of the planet's invariable plane on the Earth's mean equator of J2000. Longitudes are measured in the direction of orbital motion along the planet's invariable plane to the ring's ascending node, and thence along the ring plane. Note: For areas that cross the prime meridian, the minimum ring longitude will have a value greater than the maximum ring longitude. Note: The invariable plane of a planet is equivalent to its equatorial plane for every ringed planet except Neptune. -
attribute definition:
scaled_image_width
The scaled_image_width element provides the width on the target surface of the projection of an image onto the surface. This is the distance on the surface between intercept points 4 (middle left) and 6 (middle right). -
attribute definition:
core_high_instr_saturation
The core_high_instr_saturation element identifies a special value whose presence indicates the measuring instrument was saturated at the high end. This value must be algebraically less than the value of the core_valid_minimum element. For Standard ISIS Qubes, a value has been chosen by ISIS convention. The general data type of this element is determined by the core_item_type element. If the latter is integer or unsigned integer, the general data type is integer. If core_item_type is real, the value will be hardware- specific (or rather floating-point-representation-specific) so that it may be specified exactly near the bottom of the allowable range of values. A non-decimal (hexadecimal) general data type is used for this purpose; e.g. 16#FFFCFFFF# for a VAX. -
attribute definition:
pixel_subsampling_flag
The PIXEL_SUBSAMPLING_FLAG element indicates whether the product is the result of subsampling of the data. Subsampling is the process of measuring the brightness or intensity of a continuous image of discrete points, at an arbitrary interval, producing a new array of values. -
attribute definition:
maximum_instrument_temperature
The maximum instrument_temperature element provides the maximum temperature, in degrees Celcius, of an instrument or some part of an instrument. NOTE: for MEX, the INSTRUMENT_TEMPERATURE,MAXIMUM_INSTRUMENT_TEMPERATURE, and INSTRUMENT_POINT shall always go together and describe the actual temperatures of a part of the instrument and its maximum. For example, INSTRUMENT_TEMPERATURE = (10.2, 11.2) MAXIMUM_INSTRUMENT_TEMPERATURE = (N/A, 22.2) INSTRUMENT_POINT = (SPECTROMETER, FOCAL_PLANE) -

attribute definition:
newhorizons:sequence_id
Used in New Horizons (NH) mission instrument observation labels to identify SEQUENCE IDentifier of sequence that generated the observation. E.g. JEMV_COLOR_01 15174:PEAL_CLOSEST_APPROACH_01 This NH-specific keyword is used because PDS standard keyword SEQUENCE_ID maximum allowed lenght is too short for some of the NH values. Loose formation rules, which varied throughout the mission, are described here: May have prefix of 5-digit Load ID and colon, YYDOY:, indicating nominal day of load on which sequence was uploaded, where YY = (Year A.D.) - 2000 DOY = Day Of Year, e.g. 15185 => 2015-JUL-04 Typically next are 2 uppercase letters for mission phase or subphase: e.g. CO - COmmissioning (also sometimes LA for LAunch) JE - Jupiter Encounter (also sometimes JU) A1 - Annual checkout 1 (also A2-A8; during Pluto Cruise) PE - Pluto Encounter etc. Typically next are 2 uppercase letters for main instrument of sequence (N.B. may not be instrument of observation in label): ALice; LEisa; LOrri; MVic; PEpssi; SDc; SWap. After that is an arbitrary sequence of 7-bit ASCII characters. -
attribute definition:
mro:commanded_id
The MRO:COMMANDED_ID element gives the the actual identification value provided to the HIRISE instrument through the MRO flight system commanding. This value is returned by the HiRISE instrument through the science channel header. During flight operations the COMMANDED_ID and the OBSERVATION_ID will be identically defined. However, during calibration data acquisition at Ball Aerospace and Assembly Test and Launch Operations (ATLO), the COMMANDED_ID and OBSERVATION_ID may be different. During these phases, the same commanding, with the same COMMANDED_ID, were run repeatedly on the HiRISE instrument. The result was a non unique identification required for the OBSERVATION_ID required for this value. In these cases the OBSERVATION_ID is built from the time of the observation rather than the commaned ID found in the Science Channel Header. -
attribute definition:
logical_volumes
The logical_volumes element is an integer indicating the number of logical volumes in the given volume. If it is missing, it has a default value of 1.
