The real flyby happened at July 10, 2010 at 15:45 at a closest approach distance of about 3120 km. The magnetometer consists of two sensors, the OB and the IB sensor, mounted on a spacecraft boom. The instrument provides 3 component magnetic field vector data measured by both sensors. In this data set the calibrated and averaged and disturbance corrected data can be found. Magnetic field data are given in nanotesla. LUTETIA RPC-MAG Data Archive ========================= a) S/C DATA =========== CODMAC Level/Type Data Type Data Content 3 / CALIBRATED Data table RAW TS of OB,IB,HK data The data can be found in the ./DATA/CALIBRATED/2010/JUL directory. This directory has three subdirectories: LEVEL_A LEVEL_B LEVEL_C The LEVEL_A data (HK,IB,OB) are calibrated data in Instrument coordinates. The LEVEL_B data (IB,OB) are calibrated data in S/C coordinates. The LEVEL_C data (IB,OB) are calibrated data in ECLIPJ2000 coordinates. b) Supporting files ====================== Supporting files for the Archive user include PDS descriptions, documents, and searchable indices. These have been organized into four directories one level below the root: CATALOG, DOCUMENT,CALIB, INDEX. Structure of the volume ======================== AAREADME.TXT (PDS required introduction to the data set) VOLDESC.CAT (PDS required volume description of the data only) ./CATALOG/CATINFO.TXT (list of catalog files) *.CAT (Mission, spacecraft, instrument, data, references) ./CALIB/CALINFO.TXT (list of calib files) *.LBL (PDS Label for *.TXT files) RPCMAG_GND_CALIB_FSDPU_FMIB.TXT (Ground Calibration Parameter File for Flight SPARE DPU with FM Inboard sensor) RPCMAG_GND_CALIB_FSDPU_FMOB.TXT (Ground Calibration Parameter File for Flight SPARE DPU with FM Outboard sensor) RPCMAG_yymmdd_006_CALIB_IB.TXT (Inflight calibration Parameter for IB) RPCMAG_yymmdd_006_CALIB_OB.TXT (Inflight calibration Parameter for OB) RPCMAG_SC_ALIGN.TXT (Matrices for stowed and deployed MAG boom in relation to s/c coordinates) RPCMAG_BOOM_ALIGN_CORR_EF1.TXT (Boom Orientation correction angles obtained from EF1 Analysis.) ./DOCUMENT/DOCINFO.TXT (list of documents) *.DOC (WORD documents) *.ASC (ASCII documents) *.PDF (PDF documents) *.TEX (LaTeX documents) ./INDEX/INDXINFO.TXT (Description of the contents of the index directory) INDEX.LBL (PDS LABEL file for INDEX.TAB) INDEX.TAB (Index of the data set in tabular format) ./DATA/RESAMPLED/*.TAB (MAG data, 3 components presented as ASCII tables) *.LBL (PDS LABELS of the MAG data files) The ROSETTA project decided that the data would be archived in the PDS format. Consequently, the layout of this volume and the labels for each file conform the PDS/PSA guidelines.
