      <description>Two Fortran programs used to extract mode 1 and mode 3 measurements from the
      daily files of Apollo 15 and Apollo 17 HFE raw binary data archived in NSSDCA data sets
      PSPG-00921 and PSPG-00922 and transform to ASCII format for PDS. These programs are provided
      only for documentation purposes.</description>

    <description>The data provider, Y. Nakamura, used these Fortran programs to extract HFE mode
    1 and mode 3 measurements from daily files of HFE raw binary data archived in NASA Space
    Science Data Coordinated Archive (NSSDCA) data sets PSPG-00921 (Apollo 15) and PSPG-00922
    (Apollo 17) and transform to ASCII format. The files contained in this product are: (1)
    l1b2l1ahfem1cpds.f - the Fortran program to extract mode 1 measurements from daily binary
    files then transform and combine into one ASCII-formatted data file
    a15_hfe_1975_l1_arcsav_1.tab; (2) l1b2l1ahfem3cpds.f - the Fortran program to extract mode 3
    measurements from daily binary files then transform and combine into one ASCII-formatted
    data file a15_hfe_1975_l1_arcsav_3.tab; (3) l1b2l1ahfem1cpds_variables.pdf - defines the
    variables used in l1b2l1ahfem1cpds.f; (4) l1b2l1ahfem3cpds_variables.pdf - defines the
    variables used in l1b2l1ahfem3cpds.f; and (5) 1b2l1ahfepds.pdf - summary of the programs
    used to generate HFE raw ASCII files for PDS from ARCSAV-tape-based files.</description>
