Introduction

  This data set contains calibrated, 750-nm filter images of Earth            
  acquired by the Deep Impact Medium Resolution Visible CCD (MRI)             
  during the EPOCh and Cruise 2 phases of the EPOXI mission.  The MRI         
  instrument was only used during the first Earth observing period on         
  18-19 March 2008 and the last two on 27-28 March and 04-05 October          
  2009.  Each observing period lasted approximately 24 hours, and one         
  MRI image was taken simultaneously with the first north/south scan          
  of the HRI IR spectrometer at half-hour intervals to serve as               
  context spectra.  On 27-28 September 2009 during the first attempt          
  at Earth south polar observations, a full set of MRI context                
  images was acquired although the HRII and HRIV instruments                  
  were turned off by fault protection shortly after the sequence              
  started.

  All text documents and other meta information files such as

  stream format files, with a carriage return (ASCII 13) and a line           
  feed character (ASCII 10) at the end of the record.  This allows            
  the files to be read by various operating systems.

  list every file in each directory.  In the table, directory names           
  are surrounded by forward slashes (/), and the top-level of the             
  volume is indicated by a single forward slash.  See the *INFO.TXT
