***** File HAL_0005.TXT                                                       
                                                                              
     For each CD-ROM, the documentation and index files contain statistics    
about the images.  Some of these text files contain erroneous information.  A 
summary review of the disk also revealed some inconsistences and other        
mistakes.   This file lists the mistakes and gives corrections.               
                                                                              
     The byte count in the first SFDU label in the VOLDESC.SFD is not         
correct; the value should be 3494.                                            
                                                                              
     The file EPHEM.HDR does not correctly describe the EPHEM.IDX file; a     
blank was deleted from the third column (HOURS) and inserted in the fourth    
(JULIAN DAY).  The FITS header should contain the corrected format keyword    
- TFORM04 = 'F2.1    '- for the HOURS column description.                     
                                                                              
     The IMAGUIDE.TXT file was mistakenly copied from a master set of         
documentation that describes a selected set of images during Halley Armada    
Week (Mar 6-14, 1986).   The first paragraph should be omitted or simply      
use a correct copy duplicated on the other volumes.
