Introduction

  This data set contains calibrated, 1.05- to 4.8-micron spectra of Earth     
  acquired by the High Resolution Infrared Spectrometer (HRII) during         
  the EPOCh and Cruise 2 phases of the EPOXI mission.  Five sets of           
  observations were acquired on 18-19 March, 28-29 May and 04-05 June         
  2008 and on 27-28 March and 04-05 October 2009 to characterize Earth        
  as an analog for extrasolar planets.  Each observing period lasted          
  approximately 24 hours, and spectra were acquired twice per hour.           
  During the observing period in May 2008, the Moon transited across          
  Earth as seen from the spacecraft.  HRII spectra were not acquired          
  during the first attempt of an Earth south polar observation on             
  27-28 September 2009 because fault protection turned that                   
  instrument off; the full sequence was successfully rerun on                 
  04-05 October 2009.

  structure and content of these directories but does not exhaustively        
  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
