The Clementine EDR (Engineering Data Record) Image Archive
contains 88 CD-ROM volumes with more than 1.9 million images.
Each volume contains approximately 3 lunar orbits but may vary in
the number of orbits depending on the size of each orbit. The
first volume in the set begins with orbit number 32--the start of
the systematic lunar mapping phase of the mission. The image data
products for the engineering checkout and operational rehearsal
orbits (orbits 1-31), low Earth orbits, and earth phasing loop
orbits are located on the last eight volumes at the end of the
volume set.
