Data Set Overview : The following describes the nature of instrument operation during the various periods for which IES data are available in this submission. In all cases the data are raw electron and ion counts as function of energy, azimuth (direction in the instrument symmetry plane) and elevation (angle above or below the symmetry plane). Except for most of the data obtained during the first Earth Swingby (ESB1) all data were obtained in the solar wind near 1 AU. The period from March to October 2004 represent various phases of instrument commissioning, i.e. the first exercises of IES in space after launch.  September 8-10, 2004. This data set was obtained during the first high voltage turn-on in space and shows that IES fully survived launch. The data clearly show the expected solar wind protons and alpha particles as well as the electron distribution.  September 20-23 and October 13-14, 2004. This data set was obtained during the so-called 'Interference Scenario' to investigate any possible electrical interference between instruments or spacecraft subsystems. Various combinations of instruments were operated at different times, hence the intermittent nature of the IES data.  September 23 & 30, 2004. This data set was obtained during the so-called 'Pointing Scenario' to investigate any spacecraft attitude effects on the payload. Hence the IES data show the solar wind beam changing in direction as the spacecraft orientation changed.    Parameters : N/A    Processing : All Rosetta Plasma Consortium (RPC) data packets are transmitted together during downlinks with Rosetta. RPC data are retrieved from the Data Distribution System (DDS) at European Space Operations Centre (ESOC) to a central RPC data server at Imperial College London. Data for IES is copied from the RPC central data server by IESGS at Southwest Research Institute.  The pipeline processing software is the IES Ground System (IESGS). IESGS extracts IES CCSDS packets from the RPC collective data files stored on the RPC central data server at Imperial College. These packets are used to build ion and electron data products. The data products are grouped by date and written out to PDS compliant archive data files. One data file is created for each mode used in each day. IESGS also generates the labels for the archive data files. IES science products, archive and label files, and limited spectrograms are available to team scientists on the IESGS website.

Confidence Level Overview : This dataset is used by the IES science team after processing. This is done to ensure that the archived data contains good valid products.   Review : This archival data set was examined by the IES science team prior to its acceptance by the Planetary Data System (PDS). It will later be subject to a reviews by PDS and the Rosetta data archive working group.   Data Coverage and Quality : N/A   Limitations : None.
