DATA_SET_DESC = " 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). 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. For information on how the calibrated data files are created from edited data files, please see DOCUMENT\FLUX_CALCULATION\ FLUX_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. Version History ================= Version 1 - Initial release Version 2 - Reprocessed to remove an error in the data" CONFIDENCE_LEVEL_NOTE = " 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. Caveat about using IES Level 3 Differential Energy Flux data: The background subtraction technique used in the production of the Level 3 Differential Energy Flux data does not work well for certain modes and as a result, the flux values may be slightly different from nominal. Please contact the IES team before using the data. Once the background subtraction issue is resolved, the IES team will deliver updated data. Review ====== This archival data set was examined by the IES science team prior to submission to the NASA Planetary Data System (PDS) and ESA Plantetary Science Archive (PSA). It was reviewed by PDS, PSA, and the Rosetta data archive working group. Limitations =========== None."
