    <description>The data provider, Y. Nakamura, used this Fortran program to extract HFE-related
    housekeeping data from NASA Space Science Data Coordinated Archive (NSSDCA) data sets PSPG-00918
    (Apollo 15) and PSPG-00920 (Apollo 17), which contain raw binary data from ALSEP ARCSAV tapes,
    then transform and combine into one ASCII-formatted data file for each mission,
    a15_hfe_1975_l1_arcsav_hk.tab and a17_hfe_1975_l1_arcsav_hk.tab. The files contained in this
    product are: (1) gethfehks.f - the Fortran program; and (2) gethfehks_variables.pdf - defines
    the variables used in the Fortran program.</description>
