   This dataset contains data obtained through the efforts of the             
International Halley Watch (IHW) Disciplines and the Lead Center. From the    
original compact disk (one of a 2-disk set), several datasets have been       
created, one for each instrument of each spacecraft.                          
   The data contained in this dataset contains the data taken by the Giotto   
OPTICAL PROBE EXPERIMENTExperiment (OPE). The dataset contains also           
documentation included in the original disk.                                  
                                                                              
     In addition to the data themselves, the disks contain a wide variety of  
supporting files and tools for the Archive user; the major categories are     
documentation, ephemeris information, searchable tables and indices, and      
software (source code as well as executable modules).  These have been        
organized in three principal directories one level below the root: DOCUMENT,  
INDEX, and SOFTWARE.
