Data from the Voyager 2 magnetometer has been archived in two different       
coordinate systems for the Neptune encounter - Neptune Longitude System (NLS) 
coordinates and Heliographic (HG) coordinates. The data taken in the solar    
wind and sheath is archived in HG coordinates and the magnetospheric data is  
given in NLS coordinates. Data in each of these regions is archived in        
sub-directories which bear the name of coordinate system abbreviation.        
                                                                              
In addition to the magnetic field dataset, the magnetometer team has provided 
a dataset that is constructed for use in magnetic modeling programs. The data 
are stored in INTERNAL.TAB, an ascii table in the NLS/ASCII directory.
