RO-C-RPCIES-3-ESC1

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 calibrated differential electron and ion energy flux as function of energy, azimuth (direction in the instrument symmetry plane) and ^ation (angle above or below the symmetry plane). IES measured solar wind plasma continuously throughout this phase except for an occasional brief period if the S/C pointing was not optimal. Frequently low energy (<50 eV) ions were observed. These ions are believed to have been produced locally by photoionization and attracted to the S/C when charged negatively by an electron cloud. In addition, higher energy (~keV) pickup ions were observed from time to time. 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 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.
