attribute definition:
fast_hk_pickup_rate
The fast_hk_pickup_rate element provides the rate at which fast housekeeping is collected. Fast housekeeping is a partial gathering of the available engineering data values, or items, that pertain to and describe the condition of the instrument itself. Note: For Cassini, this value (n) is stored in the band suffix, or backplane, of the spectral cube for the infrared channel. If (n) is set to zero, then housekeeping values will be collected at every pixel (i.e., every pixel of the backplane will have a value). If (n) is set from 1 to swath_length, then housekeeping values will be collected every nth line (i.e., only the first pixel of every nth line of the backplane will have a value). If no infrared housekeeping items were selected for the cube, then this keyword will not be present. -

average_orbit_peri_tdb_time
The average_orbit_peri_tdb_time element provides the value of the periapsis time of the predicted orbit.

It represents an average over the entire orbit, and is not the result of post-orbit navigation solutions. The elements should be used for comparison purposes only, since they may involve large errors. The predicted orbit elements are copied from the orbit header file of the ALT-EDR tape, or, if unavailable, from the orbit header file of the C-BIDR. -
attribute definition:
sampling_parameter_resolution
The sampling_parameter_resolution element identifies the resolution along the sampling parameter axis.

In this example, the sampling parameter resolution would be 0.001. Note: The unit element identified the unit of measure of the sampling parameter resolution. -

attribute definition:
local_true_solar_time
The LOCAL_TRUE_SOLAR_TIME element describes the local true solar time, or LTST. It is one of two types of solar time used to express the time of day at a point on the surface of a planetary body. LTST is measured relative to the true position of the Sun as seen from a point on the planet's surface. The coordinate system used to define LTST has its origin at the center of the planet. Its Zaxis is the north pole vector (or spin axis) of the planet. The X-axis is chosen to point in the direction of the vernal equinox of the planet's orbit. (The vernal or autumnal equinox vectors are found by searching the planetary ephemeris for those times when the vector from the planet's center to the Sun is perpendicular to the planet's north pole vector. The vernal equinox is the time when the Sun appears to rise above the planet's equator.) Positions of points in this frame can be expressed as a radius and areocentric 'right ascension' and 'declination' angles. The areocentric right ascension angle, or ARA, is measured positive eastward in the equatorial plane from the vernal equinox vector to the intersection of the meridian containing the point with the equator. Similarly, the areocentric declination is the angle between the equatorial plane and the vector to the point. LTST is a function of the difference between the ARAs of the vectors to the Sun and to the point on the planet's surface. Specifically, LTST = (a(P) - a(TS)) * (24 / 360) + 12 where, LTST = the local true solar time in true solar hours a(P) = ARA of the point on the planet's surface in deg a(TS) = ARA of the true sun in degThe conversion factor of 24/360 is applied to transform the angular measure in decimal degrees into hours-minutes-seconds of arc. This standard representation divides 360 degrees into 24 hours, each hour into 60 minutes, and each minute into 60 seconds of arc. The hours, minutes, and seconds of arc are called 'true solar' hours, minutes, and seconds when used to measure LTST. The constant offset of 12 hours is added to the difference in ARAs to place local noon (12:00:00 in hours, minutes, seconds) at the point where the Sun is directly overhead; at this time, the ARA of the true sun is the same as that of the surface point so that a(P) - a(TS) = 0. The use of 'true solar' time units can be extended to define a true solar day as 24 true solar hours. Due to the eccentricity of planetary orbits and the inclination of orbital planes to equatorial planes (obliquity), the Sun does not move at a uniform rate over the course of a planetary year. Consequently, the number of SI seconds in a true solar day, hour, minute or second is not constant. See also LOCAL_MEAN_SOLAR_TIME. (Definition adapted from [VAUGHAN1995].) This element replaces the older MPF_LOCAL_TIME, which should no longer be used. -

radiance_offset

attribute definition:
planet_day_number
The planet_day_number element indicates the number of sidereal days (rotation of 360 degrees) elapsed since a reference day (e.g., the day on which a landing vehicle set down).

Note: For MPF, the planet_day_number was measured from 1 rather than 0 as the first day of surface operations. Negative numbers referred to pre-surface (cruise) images. -
