Data Set Overview
  =================
  This data presented with this data set include
 
  IRASPOS.TAB - The IRAS Position File describes the position of the
    satellite in its orbit about the Earth at 200 second intervals in
    heliocentric ecliptic rectangular coordinates (B1950), where the
    X axis points to the First Point of Ares. In addition an Earth
    ephemeris is also included, which was generated by Miles Standish
    at JPL using the information that was available in 1983 to best
    approximate the knowledge of the Earth's position that was used
    in the reduction of the IRAS data.  Finally, the geocentric
    position of the satellite is calculated using the above
    information.
 
  SCAN.TAB - The IRAS Scan History File describes the pointing
    geometry and length of each survey-mode scan (by SOP OBS) over
    the entire mission.
