The PDS labels on this volume conform to the Data Dictionary distributed      
with Release 4.1 of the PDS Toolkit. All TEXT, HEADER, SPICE KERNEL and       
TABLE objects obey GENERIC PDS standards, except that some TABLE objects      
are not accompanied by sets of COLUMN sub-objects, in which case format       
information is included in an accompanying DESCRIPTION element.               
                                                                              
The PDS Catalog files, *.CAT, conform to the PDS "streamlined" standards      
introduced in April 1994.                                                     
                                                                              
With exceptions noted below, all *.DAT files in the data directories          
were copied directly from ALT-EDR product tapes without change. Error         
messages from the PDS label generation routines have been copied to the       
ERR.TXT files within the data directories. Most errors are concerned          
with incorrect SFDU lengths, and the object pointers in the label files,      
e.g. ^TABLE = ("SAB.DAT",566), should be used in preference to the            
object lengths recorded in the *.DAT files themselves.                        
                                                                              
Some entries in the PRODUCT column in INDEX.TAB and CUMINDEX.TAB files        
on MG_3315 through MG_3337 are unreliable. Use CUMINDEX.TAB on later          
disks for the correct names of ALT-EDR product tapes.
