attribute definition:
quaternion
The QUATERNION element specifies a quaternion, which is a four-component representation of a rotation matrix. This particular definition is focused on the PDS use of quaternions; one should refer to other sources for a more complete discourse on quaternion math. A quaternion may be used to specify the rotation of one Cartesian reference frame--sometimes referred to as the base frame or the 'From' frame--into coincidence with a second Cartesian reference frame--sometimes referred to as the target reference frame or the 'To' frame. Unlike an Euler rotation where three sequential rotations about primary axes are used, a quaternion rotation is a single action, specified by a Cartesian vector used as the positive axis of the rotation (right hand rule) and the magnitude (an angle) of rotation about that axis. The quaternion may be thought of as defining the instantaneous orientation--sometimes called 'pointing'--of a structure such as an instrument, antenna, solar array or spacecraft bus, given relative to a specified reference frame (the base frame), at an epoch of interest. Perhaps of more use is the concept that a quaternion may be used to rotate an arbitrary Cartesian 3-vector defined in one reference frame (e.g. an instrument's reference frame) to an equivalent vector defined in another reference frame (e.g. the frame tied to a spacecraft or the J2000 inertial reference frame). A quaternion has four components. One of the components is a scalar, a function of the angle of rotation (cosine of half the rotation angle), while the remaining three components are used to specify a vector, given in the base reference frame, about which the rotation will be made. In the PDS context a quaternion has a magnitude of one, and so may be treated as a unit quaternion. In many cases a time tag (epoch) must be associated with the quaternion because the orientation varies over time. A time tag is not needed if the 'To' and 'From' frames have a fixed offset. The QUATERNION_DESC element is always to be paired with the QUATERNION element, and will contain a complete description of the formation and rotational sense of the quaternion specified with the QUATERNION keyword, and the structure (organization of the four components) of the quaternion. In the lingo of the NASA 'SPICE' ancillary information system a rotation matrix is synonymous with a C-matrix--that which may be obtained from a C-kernel. The SPICE Toolkit provides an assortment of routines that deal with quaternions. The SPICE system also provides information about specification of reference frames and time tags suitable for use with quaternions in the SPICE context. The NAIF Node of the PDS can provide additional documentation on quaternions in a spacecraft ancillary data context ('Rotations Required Reading' and 'SPICE Quaternion White Paper'). -

attribute definition:
reticle_point_longitude
The reticle_point_longitude element provides the longitude of the surface intercept points of the principle points of the camera. Note: For the Clementine cameras the principle points are defined as the upper left pixel of the camera (line 1,sample 1), the upper right pixel (line 1, last sample), lower left (last line, sample 1), and lower right (last line, last sample). -

received_packets

attribute definition:
background_sampling_frequency
The background_sampling_frequency element provides the number of lines between background samples. In a scanning type camera, background refers to the dark current measurement that is taken, with the camera shutter closed, while the scanner returns to the beginning of the next line. The value of the background may then be subtracted from the data to produce a more accurate measurement.
