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 calibrated differential electron and ion energy flux as function of energy, azimuth (direction in the instrument symmetry plane) and elevation (angle above or below the symmetry plane). The Rosetta Comet Escort 3 (ESC3) covers the period from 2015-July-01 to 2015-October-21, with Rosetta at various trajectories and distances from the comet. IES measured electrons generally below 200 eV. There are brief moments in which the electron detection is at all energies. The solar wind was not always visible in the RPC-IES FOV but pickup ions of energies up to ~several keV were frequently seen. Occasional gaps in the data are the result of telemetry dropouts. On 13 August at 02:30 UT Rosetta passed through perihelion, its closest distance from the Sun, 1.24 AU, and ~327 km from the comet. On 23 September 2015 Rosetta began an excursion sunward of CG, reaching a distance of ~1500 km from the comet, then returning and resuming its previous type of trajectories. At the end of this phase Rosetta was ~421 km from CG and 1.49 AU from the Sun. 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.
