Overview:                                                                     
=========                                                                     
This data set contains moments data (density and velocity) derived from       
calibrated data obtained by the                                               
Ion Composition Analyzer (RPC-ICA) onboard ESA's ROSETTA spacecraft.          
The data has been treated to remove some cross talk between different         
sectors (look directions) and mass channels. The moments have been calculated 
Using integration over available energy range and look directions.            
The solar wind ions have been semi-manually selected when instrument mass     
resolution allowed this. The value zero in the solar wind ions (H+,H2+,He+)   
Typically means that no solar wind ions were observed, but in the preliminary 
data set it may also mean that mass resolution was too poor to allow mass     
separation using mass data.                                                   
Often it is in such cases possible to determine mass from the energy spectra. 
This has not been done for this data set.

The ROSETTA project decided that the data would be archived in the PDS        
format. Consequently, the layout of this volume and the labels for each file  
conform the PDS guidelines.
