DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION 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 ion and electron density, temperature, and velocity moments. Rosetta Comet Escort 1 (ESC 1) covers the period from 2014-November-20 to 2015-March-10. IES measured electrons generally below 500 eV. There are brief moments in which the electron detection is at all energies. IES electron detector observed ICA interference as a repetitive Morse code pattern. IES measured solar wind plasma continuously throughout this phase. IES detected solar wind alpha particles during most of this phase. 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. For information on how the derived data files are created from calibrated data files, please see DOCUMENT\MOMENTS_CALCULATION\ MOMENTS_CALCULATION.PDF. Coordinate System : In order to determine IES pointing, attitude data for the Rosetta spacecraft is obtained through SPICE kernels. Level 5 files use Comet-centered Solar EQuatorial (CSEQ) as the reference frame to specify the velocity direction components. This is a common frame used in many other data sets and is referenced as '67P/C-G_CSEQ' in SPICE. SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in the Cheops reference frame. These parameters are computed at time t:START_TIME. Distances are given in km, angles in degrees.
