  Non-Standard Practices                                                     
The PDS standards do not specify where to store the required MD5 checksum    
file for a volume.  We have placed it in the root dircetory of the volume    
with the file name "CHECKSUMS.TXT".  This may be considered invalid by some  
verifiers.                                                                   
                                                                             
ASCII versions of documents have '.TXT' extensions, which is a variance from 
the PDS standards that expect '.ASC'.                                        
                                                                             
                               ERRATA                                        
---------------------------------------------------------------------------- 
                                                                             
/DOCUMENT/*/*.ASC and /DOCUMENT/*/*.HTM                                      
                                                                             
Copies of previously published documents found on the /DOCUMENT/ sub-        
directories contain some known misspellings. These may either result from    
misspellings that follow the original documents or else errors introduced    
in the transmission of these documents to ASCII and HTML format.             
                                                                             
---------------------------------------------------------------------------  
/DOCUMENT/INSTRUMENT/*.PDF                                                   
                                                                             
The PDF files are formatted in ADOBE PDF 1.3 or 1.4, not in the expected     
PDFA format.                                                                 
---------------------------------------------------------------------------  
                                                                             
Viewability of /DOCUMENT/*/*.GIF files                                       
                                                                             
The viewability of some of these images may depend significantly upon the    
operating system and the viewer used to view them. Specifically, they are    
best viewed on a color monitor.                                              
                                                                             
---------------------------------------------------------------------------  
                                                                             
PDS labels in /DOCUMENT/*                                                    
                                                                             
All of the document labels have been updated/corrected to describe ASCII     
files as RECORD_TYPE = STREAM rather than VARIABLE_LENGTH. In addition,      
the RECORD_TYPE of GIF files has been changed to UNDEFINED.                  
                                                                             
---------------------------------------------------------------------------- 
                                                                             
PDS labels in /DATA/*                                                        
                                                                             
All of the data file labels have been corrected so that the INSTRUMENT_NAME  
value is now the full instrument name rather than the instrument ID which    
is not unique across spacecraft/missions.                                    
                                                                             
---------------------------------------------------------------------------  
                                                                             
ASCII data file record formats                                               
                                                                             
ASCII data tables contained on this volume are fixed width and space         
delimited. The PDS Standards recommend using fixed width comma delimited     
fields in ASCII tables. In general this recommendation was not followed on   
this volume in order to provide data in the same format in which they were   
originally provided to the PDS.                                              
                                                                             
---------------------------------------------------------------------------  
                                                                             
SPLASH Software limitations                                                  
                                                                             
The version of the SPLASH software that was available at the time of the     
production of this volume was unable to correctly resolve ARRAY, and         
CONTAINTER objects and repeated ITEMS. As a result, some files or columns    
may not plot correctly for the following data: COSPIN-AT, EPAC, and URAP.
