RO-C-RPCIES-3-EXT1

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). Rosetta began this interval at a distance of about 90 km from the nucleus then proceeded in approximately elliptical orbits primarily in the terminator plane, gradually decreasing the distance to about 12 km in 14 March 2016. Rosetta then began its tail excursion, moving to a distance of 1000 km antisunward of the comet on 30 March 2016. The S/C then returned to the vicinity of the comet, reaching a distance of ~200 km on 5 April 2016. IES operated continuously during this period. 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.
