The improved geometry elements were derived as a by-product of the compilation of the basemap, and supersede data originally provided by the Clementine Mission through the Naval Research Laboratory. All geometry elements are in the J2000 coordinate system, the coordinate system used by the SPICE system of the Planetary Data System. The primary geometry consists of four vectors: Camera-Angles (declination, right-ascension, twist), Planet-Angles (declination, right-ascension, and spin), Spacecraft Vector, and Sun Vector. Each row in the table contains the geometry of a single Clementine EDR frame. Each record consists of 432 bytes, with a carriage return/line feed sequence in bytes 431 and 432. This allows the table to be treated as a fixed length record file on hosts that support this file type and as a normal text file on other hosts."
