The PI of the team is Karl-Heinz Glassmeier. The data have been measured during -the STEINS flyby between September 1 and September 10, 2008 The closest approach (CA) took place on September 5, 2008 at 18:38 All magnetic field data are calibrated, resampled data. That means the data represent the 3 components of the magnetic field measured in physical units (nT). Calibration has been applied according to the Ground calibration results which means: - temperature dependent offset calibration - temperature dependent sensitivity calibration - temperature dependent misalignment calibration Data are given in different coordinates, dependent on the calibration LEVEL. LEVEL_F : averaged data in s/c-coordinates Source of these data are either LEVEL_B or LEVEL_K data. LEVEL_G : averaged data in ECLIPJ2000-coordinates Source of these data are either LEVEL_C or LEVEL_L data. LEVEL_H : averaged data in ECLIPJ2000-coordinates, Reaction wheel influence eliminated, Data available for disturbed times only Source of these data are either LEVEL_C or LEVEL_L data. Bad vectors have been removed. Any s/c caused residual magnetic fields are not eliminated. The ground temperature model for the sensor calibration has been improved (expanded for a wider temperature range down to - 130 deg C) using long term temperature model obtained from flight data. The data are sorted by the sensor (OB: outboard sensor, IB: inboard sensor)and the measurement mode (M1..M6) and average interval (A, where n denotes the average interval in seconds). Data can uniquely be identified by their file names. Averaging means calculating a mean value of of the specified interval in time domain. It does not mean any mixing of data from the OB and IB sensor. 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 has been tested especially during the commissioning phases. In cases were the PRIMARY and SECONDARY sensor were toggled the individual data files (OB/IB) will contain data measured with different sampling rates according to the actual sampling rates of the PRIMARY and SECONDARY sensors. Refer to the MODE DESCRIPTION table below. The actual sampling rate is the only indicator showing which sensor is the primary and which is the secondary one. LEVEL_H data were only generated if the signature of the Reaction wheel rotations showed up in the calibrated data. A correction could be achieved for only for higher frequently sampled data. For sample rates below one Hertz the disturbing spectrum of the Reaction Wheels can hardly be distinguished from the background spectrum. Therefore only burst mode data of the OB sensor are corrected.

The actual mode and the primary sensor of the instrument can easily be identified by analyzing the filename of the actual data files. The complete filename convention is listed in the EAICD, chapter 3.1.4. The filenames for RESAMPLED averaged data (CLE,CLF,CLG,CLI) are coded as follows: ___A. RPCMAG yymmdd CLE IB A60 LBL CLF OB TAB CLG CLI Example: RPCMAG040528_CLG_OB_A20.LBL RPCMAG040528_CLG_OB_A20.TAB Average denotes the time interval for one average period in seconds. The filenames for RESAMPLED Heater or Reaction Wheel influenced data (CLK, CLL, CLH) are coded as follows: ___. RPCMAG yymmddThhmm CLK IB M1..M6 LBL CLL OB TAB CLI Example: RPCMAG040528T1230_CLK_OB_M3.LBL RPCMAG040528T1230_CLK_OB_M3.TAB Geometry Information - Coordinate System ======================================== The geometry items SC_SUN_POSITION_VECTOR SC_TARGET_POSITION_VECTOR SC_TARGET_VELOCITY_VECTOR provided in the label of the data product are relative to the ECLIPJ2000 frame. This reference frame is built up by Ecliptic Coordinates 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 up The items SUB_SPACECRAFT_LATITUDE SUB_SPACECRAFT_LONGITUDE are 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.
