Hycon B/W Photometric 5-in. Photos


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1971-01-31 to 1971-02-09


This data set contains usable b/w 3400 film photography taken with the 127-mm (5-in. wide film) Hycon topographic camera with a 457-mm (18-in.) focal length lens on magazines V and W. The originals were reproduced on a Niagara printer to preserve the albedo variations more faithfully. Thus, these pictures can be used for photometric and photo-grammetric studies. The photographs include vertical stereo coverage (on revolution 4) of the Descartes Highland region from 30 deg E to 9.5 deg E, the Apollo 16 landing area. Coverage beyond 17.4 deg E, 9.3 deg S was not usable owing to a camera malfunction. The stereo coverage from 28.1 deg E to 17.4 deg E is of good quality. The frames cover areas about 5 by 280 km (3 by 170 nautical miles), and coverage extends from the eastern (IAU) rim of Theophilus to Dollond MA. The altitude of the spacecraft on this pass varied from 12.5 to 20 km (10 to 12 nautical miles) depending on ground elevation. Resolution limits the range from 2 to 3 m. Although the overall quality is good, some frames appear blurred on the edges.
