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 raw electron and ion counts as function of energy, azimuth (direction in the instrument symmetry plane) and elevation (angle above or below the symmetry plane). This data set includes data obtained by IES during the period 10 May 2010 to 10 September 2010 (referred to as the AST2 flyby period by ESA for reference although instrument operation was not continuous during this period). The period between 10 to 13 July 2010 encompassed the asteroid Lutetia flyby. The actual flyby of the asteroid occurred on 9 July 2010 when IES was not operating. Thus only solar wind data were obtained. During the period between 0300 UTC on 11 July 2010 to 1100 UTC on 12 July 2010 no IES data were obtained. 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. Coordinate System : In order to determine IES pointing, attitude data for the Rosetta spacecraft is obtained through SPICE kernels and converted from the J2000 coordinate system to the HGRTN coordinate system. HGRTN is the heliocentric RTN system such that the sun-spacecraft vector defines the positive x-axis and the positive y-axis is the cross-product of the heliographic polar axis and the HGRTN positive x-axis. J2000 is the inertial frame defined by the intersection of the Earth mean equator and the ecliptic plane at the J2000 epoch of January 1, 2000 at noon. The pointing for each bin of IES is thereafter determined by multiplying the converted spacecraft attitude matrix in HGRTN by the vector representation of each particle measurement bin. The resulting vectors represent the flow of particles through the respective particle measurement bins in HGRTN coordinates.

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. Review : This archival data set was examined by the IES science team prior to submission to the Planetary Data System (PDS) and was then reviewed by PDS and the Rosetta data archive working group. The current set is a resubmission after correcting or responding to the various RIDs resulting from that review. Limitations : None.
