Catalog of Information on Mission Frames and How They Were Microdensitometered (Digitized)

NSSDCA ID: ASUV-00074

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

Time span: 1972-04-21 to 1972-04-23

Description

This collection is the digitization of a microfilm of the 476-page catalog submitted by Dr. T. Page to accompany the magnetic tapes that contain the microdensitometer (dicomed model 57) scan results of the 209 mission frames gathered on the lunar surface by the Apollo 16 far-UV camera/spectrograph experiment. The 209 mission frames consist of 190 UV pictures and 19 calibration frames. A number of these frames were scanned more than once. In addition, during the microdensitometer scans many passes were made of a gray-scale, step-wedge as a qualitative control variable on the scanning procedure. In all, 476 microdensitometer scans were made, and the information about each scan is contained on a single catalog page.

The nature of the information given on each microdensitometer scan makes this catalog useful for four purposes: (1) the source of general information on each of the mission frames because the pages give data on camera pointing, filter(s) used, exposure time, objects visible, etc.; (2) an adjunct to the viewing of the mission frames; (3) an essential guide in determining the location of the microdensitometer scan(s) of the mission frames on the digitized-scan magnetic tapes; and, (4) the source of information on how the scans were performed and the size of the scans.

Copies of the mission frames and the digitized-scan magnetic tapes are available through NSSDC as data collections ASUV-00048 and ASUV-00017, respectively.

For this digitization effort the NSSDCA scanned the source microfilm collection ASUV-00061 at a resolution of 400 dots per inch and output each frame on the film as one TIFF file. The NSSDCA also combined groups of these TIFF images into multipage PDF files to facilitate browsing. Both formats are included in this collection.
