      <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
      from 30 July to 4 August 1971 by the Apollo 15 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>
