 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. General information            
 about the Infrared Astronomical Satellite (IRAS) and its mission may be      
 found in Beichman et al. (1988) and Neugebauer et al. (1984). 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.  For information on expected modulations of the 
 orbit over the mission see LUNDY&MCLAUGHLIN1979."
