Data Set Overview:The data from the ROSETTA PLASMA CONSORTIUM (RPC) FluxgateMagnetometer(MAG)was submitted by Ingo Richter (TM) for the RPCMAGteam. The PI of the team is Karl-Heinz Glassmeier.The data have been measured during -the LUTETIA flyby between July 7 and July 13, 2010The closest approach (CA) took place on July 10, 2010 at 15:45All magnetic field data are calibrated, resampled data. That means thedata represent the 3 components of the magnetic field measured inphysical units (nT). Calibration has been applied according to theGround calibration results which means:- temperature dependent offset calibration- temperature dependent sensitivity calibration- temperature dependent misalignment calibrationData are given in different coordinates, dependent on the calibrationLEVEL. LEVEL_F : averaged data in s/c-coordinates Source of these data are LEVEL_B data. LEVEL_G : averaged data in ECLIPJ2000-coordinates Source of these data are LEVEL_C data. LEVEL_H : averaged data in ECLIPJ2000-coordinates, Reaction wheel influence eliminated, Data available for disturbed times only Source of these data are LEVEL_C data.Bad vectors have been removed. Any s/c caused residual magnetic fieldsare not eliminated. The ground temperature model for the sensorcalibration has been improved (expanded for a wider temperature rangedown to - 130 deg C) using long term temperature model obtainedfrom flight data.The data are sorted by the sensor (OB: outboard sensor, IB: inboardsensor)and the measurement mode (M1..M6) and average interval (A,where n denotes the average interval in seconds). Data can uniquely beidentified by their file names.Averaging means calculating a mean value of of the specified intervalin time domain. It does not mean any mixing of data from the OB and IBsensor.Normally the OB is the Primary (Pri) and the IB is the Secondary (Sec)sensor. However, this order can be toggled by TCs. This feature hasbeen tested especially during the commissioning phases.In cases were the PRIMARY and SECONDARY sensor were toggled theindividual data files (OB/IB) will contain data measured withdifferent sampling rates according to the actual sampling rates ofthe PRIMARY and SECONDARY sensors. Refer to the MODE DESCRIPTIONtable below. The actual sampling rate is the only indicatorshowing which sensor is the primary and which is the secondaryone.LEVEL_H data were only generated if the signature of the Reactionwheel rotations showed up in the calibrated data. A correction couldbe achieved for only for higher frequently sampled data. For samplerates below one Hertz the disturbing spectrum of the Reaction Wheelscan hardly be distinguished from the background spectrum. Thereforeonly burst mode data of the OB sensor are corrected.Mode description::MODE SAMPLE RATE PACKET PERIOD PACKET LENGTH VECTOR RATEMinimum Mode M1 1/32 Hz 1024 s 32 Pri Vec 0.03125 vec/s 1 Sec Vec 0.000976 vec/sNormal Mode M2 1 Hz 32 s 32 Pri Vec 1 vec/s 1 Sec Vec 0.03125 vec/sBurst Mode M3 20 Hz 16 s 320 Pri Vec 20 vec/s 16 Sec Vec 1 vec/sMedium Mode M4 5 Hz 32 s 160 Pri Vec 5 vec/s 1 Sec Vec 0.03125 vec/sLow Mode M5 0.25 Hz 128 s 32 Pri Vec 0.25 vec/s 1 Sec Vec 0.007812 vec/sTest Mode M6 20 Hz 16 s 320 Pri Vec 20 vec/s 1 Sec Vec 0.0625 vec/sHK Mode 32 s 8 words 0.03125 vec/sFILENAME CONVENTION & Mode Coding:Due to operational constraints it might happen that the instrumentmode or the primary sensor has to be switched during a specificobservation.The actual mode and the primary sensor of the instrument can easilybe identified by analyzing the filename of the actual data files. Thecomplete filename convention is listed in the EAICD, chapter 3.1.4.The filenames for RESAMPLED averaged data (CLF,CLG) are codedas follows: ___A.RPCMAG yymmdd CLF IB A60 LBL CLG OB TABExample: RPCMAG040528_CLG_OB_A20.LBL RPCMAG040528_CLG_OB_A20.TABAverage denotes the time interval for one average period in seconds.The filenames for RESAMPLED Heater or Reaction Wheel influenced data(CLH) are coded as follows: ___.RPCMAG yymmddThhmm CLH IB M1..M6 LBL OB TABExample: RPCMAG040528T1230_CLH_OB_M3.LBL RPCMAG040528T1230_CLH_OB_M3.TABGeometry Information - Coordinate System:The geometry items SC_SUN_POSITION_VECTOR SC_TARGET_POSITION_VECTOR SC_TARGET_VELOCITY_VECTORprovided in the label of the data product are relative to theECLIPJ2000 frame. This reference frame is built up by EclipticCoordinates related to Equinox of Epoch J2000.Orientation: X: Pointing from SUN to Vernal Equinoxe, Y: perpendicular to X in Ecliptic Plane, Z: Perpendicular to Ecliptic plane, pointing upThe items SUB_SPACECRAFT_LATITUDE SUB_SPACECRAFT_LONGITUDEare given in the PLANETOCENTRIC coordinate system.All these geometry parameters are computed at time t:START_TIME.Distances are given in km, angles in degrees.

This data set has been reviewed by two independent teams in Spring 2012. After these reviews the data set has been accepted by the Planetary Science Archive(PSA)of the ESA and by the Planetary Data System(PDS) of NASA for long-term archiving. The data have been processed on best effort basis according to the procedures described in RO-IGEP-TR0028: Step by Step Calibration Procedure. Quality flags are attached for CALIBRATED and RESAMPLED data as described in the EAICD RO-IGEP-TR0009. Both of these are available in the DOCUMENT directory.
