This directory contains the PIONEER 11 trajectory data in Pioneer             
Celestial (AE) coordinates and Kronographic (KG) coordinates during           
the Saturn encounter period.  The data set contains the spacecraft            
ephemeris time, ground received time, latitude and longitude of               
the Earth, Sun, and the spacecraft, spacecraft temporary angle                
and its distance from Saturn.                                                 
                                                                              
The data are stored as one ASCII table files (.TAB), accompanied by           
a PDS label file (.LBL) which describes the properties of the data            
file.
