The PI of the team is Karl-Heinz Glassmeier. The data have been measured during - The second Earth Flyby (EAR2) in the time period November 7, 2007 - November 20, 2007 There is a data gap from - November 8, 01:11 until November 12, 15:53 due to an Single event latchup (SEU). Refer to the Swingby report RO-IGEP-TR-0023 for further details All magnetic field data are calibrated data. That means the data represent the 3 components of the magnetic field measured in physical units (nT). Data are given in instrument coordinates (LEVEL_A), S/C coordinates (LEVEL_B) or ECLIPJ2000 coordinates (LEVEL_C). Calibration has been applied according to the Ground calibration results which means: - temperature dependent offset calibration - temperature dependent sensitivity calibration - temperature dependent misalignment calibration Bad vectors have been removed. Any s/c generated noise and 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). They can uniquely be identified by their file names. 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.

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 EDITED and CALIBRATED data are coded as follows: ___. RPCMAG yymmddThhmm RAW IB M1..M6 LBL CLA OB TAB CLB CLC Example: RPCMAG040528T1230_CLA_OB_M3.LBL RPCMAG040528T1230_CLA_OB_M3.TAB The filenames for Housekeeping data are coded as follows: _.

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.
