Data Set Overview : The data from the ROSETTA PLASMA CONSORTIUM (RPC) Ion CompositionAnalyser (ICA) was submitted by Hans Nilsson for the RPCICA team. The data set contains data of mass resolved positively charged ionsin the energy range a few eV to 40 keV. The raw data is separated intomass channels or mass channel ranges, not actual ion mass. For mostcircumstances, significant counts are seen only for certaindirections, mass channels and energy levels. The data is thus sparsewith many zeros. The unit is COUNTS. This dataset contains RAW DATA from the RPCICA instrument onmission ROSETTA during the third flyby of Earth. The data containsobservations of the solar wind in the vicinity of Earth and apassage through the Earth's magnetosphere, including some radiationbelt data.

An automatic screening removing most corrupt data has been used.Some faulty data may remain, this is usually obvious from the look ofthe data. Cross-talk affects some directional and mass resolution.A quality flag also indicates data with potential problems concerningnoise levels and stability of the energy scale.
