This directory and its subdirectories contain software, and ion and nav data  
which may be used to transform the provided ion data into the rest-frame the  
of the particles. In a rapidly flowing plasma, ion detection telescopes (or   
other measurement systems) facing into the plasma flow will record more counts
than those sectors facing in other directions. This is known as the           
Compton-Getting effect, named for the classic 1935 paper. These data were     
generated by the promgram 'lem_v5.f'. For more information please refer to the
'User's Guide for lem_v5.f' (lem_v5_user_guide.asc).                          
                                                                              
The Compton-Getting (CG) effect for the inner magnetosphere of Jupiter will be
most critical for the lowest energy ions and the heavy ions detected by EPD.  
At high energies, the effect is much weaker and it is often appropriate to use
the data as a good approximation to the rest-frame data without correction.
