The very Flyby took place between March 1 and March 7 2005 with the Closest Approach on March 4, 2005 at 22:09 UTC. The dataset also contains the data from the Passive Checkout PC0 from March 29,2005. 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. EAR1 RPC-MAG Data Archive ========================= a) S/C DATA =========== 1) Averaged Data CODMAC Level/Type Data Type Data Content 4 / RESAMPLED Data table Averaged TS of OB,IB data LEVEL_E (normally not provided) LEVEL_F LEVEL_G LEVEL_H 2) Disturbance corrected data (provided if disturbance has occurred) CODMAC Level/Type Data Type Data Content 4 / RESAMPLED Data table corrected TS of OB,IB data not averaged but resampled due to filter properties LEVEL_K LEVEL_L ----------------------------------------------------------------------------- The data can be found in the DATA\RESAMPLED\2005\MAR directory. This directory has up to six subdirectories: LEVEL_E : (IB,OB) calibrated, averaged data in Instrument coordinates. Normally not sent to PSA LEVEL_F : (IB,OB) calibrated, averaged data in S/C coordinates. LEVEL_G : (IB,OB) calibrated, averaged data in ECLIPJ2000 coordinates. LEVEL_H : (IB,OB) calibrated data in ECLIPJ2000 coordinates. Influence of ROSETTA'S reaction wheels has been eliminated. Data delivered only in case of disturbance LEVEL_K : (IB,OB) calibrated data in S/C coordinates. Influence of the Lander heater currents has been eliminated. Data delivered only in case of disturbance LEVEL_L : (IB,OB) calibrated data in ECLIPJ2000 coordinates. Influence of the Lander heater currents has been eliminated. Data delivered only in case of disturbance 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_002_CALIB_FSDPU_FMIB.TXT Calibration Parameter File for Flight SPARE DPU with FM Inboard sensor RPCMAG_002_CALIB_FSDPU_FMOB.TXT Calibration Parameter File for Flight SPARE DPU with FM Outboard sensor RPCMAG_SC_ALIGN.TXT Matrices for stowed and deployed MAG boom in relation to s/c coordinates ../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/CALIBRATED/*.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.
