Overview:                                                                     
==============================================================================
The Standard Radiation Environment Monitor (SREM) performs a wide range of    
radiation monitoring functions in orbit. It is designed as standard           
equipment compatible with all common spacecraft interfaces and mission        
constraints.                                                                  
                                                                              
The level 2 SREM data sets contain count rates (1/s) as measured by the       
Standard Radiation Environment Monitor (SREM) instrument on the Rosetta       
spacecraft, along with their standard deviations.  The archive content        
and structure is summarised below.
