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.
