        DOCUMENT Directory Contents                                           
                                                                              
                                                                              
    The DOCUMENT directory contains several documents produced                
    during the second preflight thermal-vacuum test (TV2) Deep Impact         
    instruments (HRII and HRIV only):                                         
                                                                              
      - The IMAGELOG directory contains the image log document.               
        As each image was acquired during TV1, an entry was made              
        in the log.  Image parameters, such as mode and experiment            
        type, were recorded.  Images were grouped by test date.               
        The log also provides a summary of the experiments performed          
        each day and a list of the experiment types with descriptions.        
                                                                              
      - The PDSDD directory contains the local Planetary Science              
        data dictionary listing and index file, in ASCII text format,         
        for the Deep Impact thermal-vacuum data sets.  Description and        
        values of locally-defined keywords found in the data labels are       
        included in the dictionary.                                           
                                                                              
      - The READTEMP directory describes a method for reading a               
        temperature data table and interpolating between two table            
        entries.  A sample IDL function is included to illustrate the         
        method.                                                               
                                                                              
      - The REPORTS directory contains daily reports produced by              
        test personnel at the end of each test day.  Each report              
        describes the activity for that day.  This directory also             
        includes a presentation by Dennis Wellnitz to the Deep Impact         
        science team the summarizes the problems and initial results          
        from TV2.                                                             
                                                                              
    These documents are very useful for understanding the calibration         
    tests performed during TV1.  For information regarding the image          
    log or the daily test reports, please contact:
