      <description>This collection contains fixed-width ASCII files of daily raw cleaned science and
      engineering measurements acquired by the Lunar Surface Magnetometer (LSM) at the Apollo 16
      landing site for the time span of 02 April through 30 June 1975. These data were extracted
      from NASA's original Apollo Lunar Surface Experiments Package (ALSEP) archive tapes, also
      known as ARCSAV tapes, that recorded 24-hour, time-edited, and rearranged raw binary data
      transmitted from the Moon. The extracted binary data were corrected for obvious tape read
      errors then transformed to ASCII format for this archive. This collection also includes one
      ASCII file of LSM-related command verification data extracted from the ARCSAV binary
      files.</description>

      <description>Raw measurements of the three orthogonal vector components of magnetic fields at
      the lunar surface acquired by the three fluxgate sensors of the Apollo 16 Lunar Surface
      Magnetometer Experiment during the time span of 02 April through 30 June 1975. The scientific
      objectives were to measure remanent and induced lunar magnetic fields to investigate the
      following properties of the lunar interior and the lunar environment: (1) global electrical
      conductivity and temperature of the Moon, (2) lunar magnetic permeability and iron abundance,
      and (3) lunar remanent magnetic fields and their interaction with the solar wind
      plasma.</description>

      JSC-09652, NASA Johnson Space Center, Houston, Texas, USA, May 1975. This document provides
      the information needed by programmers to develop the software for retrieving raw binary
      experiment data from the original NASA ALSEP ARCSAV tapes for Apollo 16, 14, 15, 16, and 17.
      Section 1.1.1.5 describes the raw binary Apollo 16 LSM data as formatted on the ARCSAV
      tapes.</comment>

      <description>Describes in detail the Apollo 16 ALSEP (ALSEP 3, Array D) package including the
      subsystems for thermal control, electrical power, command, telemetry, and each ALSEP
      experiment. Describes all command verification codes, and their functions, used for the ALSEP
      3 station and its experiments in Section 5. Lists LSM measurements and the operating range for
      calibration and engineering data in Section 6. Section 10 discusses some operational aspects
      of the Lunar Surface Magnetometer experiment. This handbook was intended for specialized use
      by Experiment Flight Controllers in real-time and near-real-time operations of ALSEP 3. This
      document, in conjunction with the Apollo 16 ALSEP Array D Flight System Familiarization
      Manual, ALSEP MT-06, provided the Experiment Flight Controller with a thorough knowledge of
      ALSEP 3.</description>
