1. Introduction                                                               
                                                                              
This volume is part of the Cassini Orbiter Magnetometer Calibrated Data volume
set. It contains Cassini magnetometer (MAG) full-res. calibrated data covering
1999-08-16 (DOY 228) to 2016-09-30 (DOY 274).                                 
                                                                              
The Cassini Orbiter Magnetometer Calibrated Data volume set contains          
calibrated RDR (Reformatted Experimenter Data Record) magnetic-field data from
the Cassini Fluxgate (FGM) and Vector-Helium (VHM) Magnetometers. These data  
have been calibrated from the raw data, and rotated into geophysical          
coordinates by the Cassini MAG team at Imperial College. The data are in a    
variety of coordinate systems depending upon the mission phase as indicated   
in the table below:

This volume complies with Planetary Data System (PDS) standards, Version      
3.8, described in Jet Propulsion Laboratory (JPL) document JPL D-7669.        
                                                                              
Some versions of these data were determined to contain timing errors,         
including both backwards and repeated times. These timing errors have not     
been corrected in the data files. However, any timing errors that may be      
present in a data file are noted in the PDS label file that accompanies it.   
A full list of all files, and intervals containing timing errors is provided  
at:                                                                           
                                                                              
   /DOCUMENT/DATA_QUALITY/FGM_FULL_TIMING_ERRS.CSV.                           
                                                                              
A more detailed description of the timing errors is included in the data set  
catalog file:                                                                 
                                                                              
   /CATALOG/CO_MAG_CAL_FULL_DS.CAT.                                           
                                                                              
                                                                              
2. Volume format                                                              
                                                                              
This volume is organized into a hierarchical directory structure. It complies 
with both the Universal Disk Format (UDF) and the ISO 9660 (level 2) file     
system standards in order to accommodate users on a wide variety of platforms.
                                                                              
                                                                              
3. File formats                                                               
                                                                              
The data files on this volume are provided as ASCII tables (.TAB file         
extension). Each data file is accompanied by a detached PDS label file (.LBL  
extension) which contains information describing the data file and data       
record format.                                                                
                                                                              
Document files describing the volume, the data and data-calibration software  
are included in the volume. These files are provided in PDF, and HTML.        
                                                                              
Text files and detached label files contain 80-byte fixed-length ASCII        
records, with a carriage-return character (ASCII 13) in the 79th byte and a   
line-feed character (ASCII 10) in the 80th byte.  This format allows the      
files to be read by MacOS, DOS, UNIX and VMS operating systems.               
                                                                              
                                                                              
4. Volume contents                                                            
                                                                              
The files on this volume are organized into one Root directory containing     
several subdirectories. The following table shows the structure and content
