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). Rosetta Extension 1 (EXT1) covers the period from 2016-January-01 to 2016-April-05. IES observed solar wind plasma continuously throughout this phase, except for the interval of January 4-9, 2016. There are periods in this phase when we are unable to separate solar wind protons from the picked-up ions. During these intervals, no solar wind proton moments are reported. IES detected solar wind alpha particles during this phase. There are some intervals where proton moments are not reported, but alpha moments are reported. This is due to the fact that alphas are deflected less than protons, and the alpha population is at higher energies than picked up ions, which are mixed with the proton population. IES measures different electron energy populations throughout this phase, but electron moments are reported as a single unseparated population. 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." 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. The current set was peer reviewed scientifically in 2016 by external experts and the recommendations and fixes have been implemented. Limitations =========== None."
