NOTE                           = "This is a high-resolution composite         
  thermal map of the surface of comet 9P/Tempel 1 measured by the             
  Deep Impact IR spectrometer (HRII) from about 11 to 5 minutes before        
  impact and at a phase angle of about 62.9 degrees and a distance of         
  about 15900 to 11900 km.  The composite thermal map was constructed         
  from the two highest-resolution thermal maps for exposure IDs (scans)       
  9000036 and 9000039.  First, the thermal map for 9000036 at 159 m/pixel     
  was scaled to 120 m/pixel, the scale of the thermal map for exposure        
  9000039.  Then the rescaled map for 9000036 was registered against          
  the thermal map for 9000039 by shifting and rotating to align the           
  limb and terminator profile and some large surface thermal features.        
  Six lines (35-40) of thermal map 9000039 appeared to be bad during a        
  visual inspection and were therefore not used.  Finally the upper half      
  of the nucleus in thermal map 9000036 that was covered by map 9000039       
  was replaced by lines from the latter.

  SAMPLE_DISPLAY_DIRECTION keywords below, the Sun is to the right,           
  celestial north is toward the upper-right, and celestial east is toward     
  the upper-left.  The projected positive spin axis of the nucleus points
