    This volume contains images of comet 9P/Tempel, from its 1983             
    apparition, as derived from 12-, 25-, 60-, and 100-micron                 
    observations acquired by the Focal Plane Array (FPA) instrument           
    on the Infrared Astronomical Satellite (IRAS):                            
                                                                              
      - Radiance images, noise maps, and effective resolution tables          
        derived from reprocessed IRAS Additional/Pointed Observations.        
                                                                              
      - Radiance images and noise maps derived from reprocessed IRAS          
        Sky Survey Atlas scans.                                               
                                                                              
      - JPEG-rendered images of the dust trail based on data in the           
        ISSA Reject Set.  These images are provided as documentation          
        for future reference.                                                 
                                                                              
    These data support the analysis of the dust environment of Tempel 1       
    for the NASA Deep Impact Mission.                                         
                                                                              
                                                                              
    IRAS Additional Observations (AO)                                         
    ---------------------------------                                         
                                                                              
        For these data, IRAS was aimed at Tempel 1 and images were acquired   
        at  microns 12, 25, 60, and 100 microns by the FPA.  Russell Walker   
        combined the images by satellite operations plan number, reprocessed  
        the data, and produced adiance and noise maps in FITS format and      
        effective beam resolutions in ASCII table format.  An extensive       
        discussion of these data, provided by Walker, is included in the      
        documentation directory on this volume.                               
                                                                              
                                                                              
    IRAS Sky Survey Atlas (ISSA) Scans                                        
    ----------------------------------                                        
                                                                              
        Most of the IRAS observation time was spent in survey mode.           
        Walker identified ISSA scans that contained Tempel 1, then combined   
        the scans by satellite operations plan number, reprocessed the data,  
        and produced radiance and noise maps in FITS format.  An extensive    
        discussion of these data is included in the documentation directory   
        on this volume.

      Fifty-six (56) images in the ISSA showed the dust trail of Tempel 1.    
      These unprocessed images were converted from FITS to JPEG and included  
      in this data set as documentation for future reference.  A discussion   
      of these images is included in the documentation directory on this      
      volume.
