      <description>This collection contains comma-separated ASCII tables of ephemeris data
      (spacecraft state vectors, camera orientation, photograph position, and lighting data)
      computed during the Apollo era for analyzing and using photographic images taken of the moon
      on 10-16 December 1972 by the Apollo 17 Metric (Mapping) and Panoramic Cameras from lunar
      orbit. These tables were produced using optical character recognition (OCR) software to read
      TIFF images of scanned tabular output on microfilm. These scans were merged and provided in
      this collection as two PDF/A files, one for each camera.</description>
