The Deep Impact documents on this volume are grouped into the following       
directories and subdirectories:

  - The /ARCHIVE_INTERFACE_CONTROL subdirectory contains the Archive          
    Interface Control Documents that describe the flight data archive         
    for the HRII (AICD_FLIGHT_HRII.*) and the HRIV, MRI and ITS               
    (AICD_FLIGHT_HRIV_MRI_ITS.*) instruments.  These documents describe       
    the PDS data sets for raw and calibrated flight science data from         
    the four instruments.                                                     
                                                                              
  - The /LOCAL_PDS_DATA_DICTIONARY subdirectory contains the local PDS        
    data dictionary listing (PDSDD_DI.FUL) and associated index file          
    (PDSDD_DI.IDX) for the Deep Impact data sets providing flight data        
    and results.  These ASCII text dictionary files were used to validate     
    the PDS labels.                                                           
                                                                              
  - The /PROJECT_DATA_MANAGEMENT_PLAN subdirectory contains Project Data      
    Management Plan for the mission.                                          
                                                                              
  - The /QUATERNION_DESC subdirectory contains the QUATERNION.ASC document    
    describes how to use values in the QUATERNION keyword found in the        
    raw and reduced HRII, HRIV, MRI, and ITS data labels.

  -------------                                                               
  - The /CALIBRATION_DOCS subdirectory contains the Deep Impact instrument    
    calibration paper by Klaasen, et. al (2006) that describes the analyses   
    of raw ground and in-flight calibration data, the resulting calibration   
    files, and the calibration pipeline.  This document also includes a       
    summary of the types and purposes of in-flight calibrations and           
    describes image orientation.  This subdirectory also includes a           
    summary of the calibration processes (CALIBRATION_PIPELINE_SUMM*) and     
    a summary of the inflight calibrations (INFLIGHT_CALIBRATION_SUMM*),      
    both extracted from the instrument calibration document.  The             
    limitations of the calibration applied to the HRII spectral images        
    are described in HRII_CALIBRATION_LIMITATION*.  Researchers are           
    advised to read this document before using the calibrated IR data.        
                                                                              
  - The /CALIBRATION_SOFTWARE subdirectory contains the IDL procedures        
    used for calibrating Deep Impact HRII, HRIV, MRI, and ITS flight data     
    from raw counts to physical units of radiance (Watts/cm**2 sr um)         
    and reflectance (I-over-F).  The software is supplied strictly as         
    documentation for the pipeline;  it is not supported and not              
    intended to be executable.  The /DICAL_V5 subdirectory provides the       
    version of the pipeline used to calibrate version 1.0 of the reduced      
    Navigation data sets for the HRIV, MRI, and ITS instruments and           
    version 2.0 of the reduced Science data sets for the HRII, HRIV, MRI,     
    and ITS instruments.  The /DICAL_V4 subdirectory provides the version     
    of the pipeline used to calibrate version 1.0 of reduced Science data     
    sets for the HRII, HRIV, MRI, and ITS instruments.                        
                                                                              
                                                                              
  /FLIGHT_DATA                                                                
  ------------                                                                
  - The /DAY_OF_YEAR_CALENDAR subdirectory contains a calendar that converts  
    days of year for 2005 to month and day.                                   
                                                                              
  - The /IMAGE_PARAM_TABLES subdirectory contains image parameter tables      
    for raw and reduced HRII, HRIV, MRI, and ITS science data sets from       
    cruise and encounter.  It also contains image parameter tables for        
    raw and reduced HRIV, MRI, and ITS Navigation data sets from cruise       
    and encounter.  The image parameter tables include information about      
    each image in a data set such as the UTC mid-point and duration of        
    an exposure.                                                              
                                                                              
  - The /NAV_DATA subdirectory subdirectory contains documents required       
    for the understanding and interpretation of the raw and reduced           
    navigation (NAV) images data sets.  The navigation images report          
    describes how NAV FITS images were created from snipped frames,           
    processed, and reduced.  This directory also contains documents that      
    cross-reference raw and reduced FITS file names for the HRIV, MRI,        
    and ITS NAV images data sets.  The cross references are required          
    because different file-naming conventions were used for raw and           
    reduced FITS data.                                                        
                                                                              
  - The /SCIENCE_DATA subdirectory contains:                                  
    - The /ENCOUNTER_LOGS subdirectory contains the hand-recoreded image      
      logs that were maintained during the encounter with comet 9P/Tempel 1.  
      There is one log for each science instrument (HRII, HRIV, MRI, and ITS).
      During the 28 hours before impact and through encounter, instrument     
      teams were responsible for recording information about the planned      
      observations such as if the images were received on the ground, the     
      quality of the images, or a brief description of what was seen in       
      the images.                                                             
                                                                              
    - The /HRII_ENCOUNTER_POINTING subdirectory contains a table that         
      summarizes the pointing and scan directions for each HRII exposure      
      of 9P/Tempel 1 from June 20 through July 6, 2005.                       
                                                                              
    - The /HRII_HRIV_CONTEXT_IMAGES subdirectory contains a HRIV context image
      for each HRII spectral image acquired during impact and lookback.  For  
      each IR frame, the estimated location and size of the IR slit is        
      superimposed on a HRIV image taken near the IR observation.  The        
      IMPACT_CONTEXT_IMAGES.ASC and LOOKBACK_CONTEXT_IMAGES.ASC documents     
      provide a description of the context frames and how they were created.  
      IMPACT_CONTEXT_IMAGE_LOG.ASC and LOOKBACK_CONTEXT_IMAGE_LOG.ASC provide 
      a log of the context frames, including geometric parameters displayed   
      on the context images.                                                  
                                                                              
  - The /SPACECRAFT_CLOCK_CORRELATION subdirectory contains the               
    Deep Impact spacecraft clock correlation document.  This document         
    summarizes the rationale for the archived correlations between            
    the flyby and impactor spacecraft clocks (SCLKs) and dynamical            
    barycentric time that are encapsulated in the SCLK kernel files           
    archived in the Deep Impact SPICE data set.  This document also           
    explains why the clock correlation was changed about 2 seconds,           
    retroactively, shortly after impact with comet 9P/Tempel 1.
