  This data set contains broadband R images and derived on-chip differential  
  photometry of comet 9P/Tempel 1, the target of the Deep Impact mission.     
  The images included here were obtained by M. Buie at the Perkins 72-inch    
  telescope of the Lowell Observatory during 2000 apparition:

  The September and October data were obtained using the Loral 2K x 2K        
  CCD.  The November and December data were obtained using the                
  SITe 2K x 2K CCD, and the January data with the Navy TI 800 x 800 CCD.      
                                                                              
  On most nights, Landolt standard stars were observed at several             
  airmasses and with broadband VR filters to provide a measurement            
  of the extinction and a means of obtaining an absolute calibration.         
                                                                              
  The purpose of this data set is to support analysis of the rotation         
  period and dust environment of comet 9P/Tempel 1 for the Deep Impact        
  mission.
