VEX-V-Y-MAG-2

This data set comprises uncalibrated data from the Venus Express Mag (MAG) instrument in nano Tesla and in S/C coordinates. Only known sensor effects are corrected; these RAW data contain a significant amount of variable spacecraft background field. The basic data were collected during the Venus Express mission from Launch (9th November 2005) to the end of the mission. The basic data is comprised of uncalibrated raw measurement data, calibrated data, resampled data and geometry information. Also included documentation. DATA CONTENTS: HOUSEKEEPING data: NO HK data (temperatures, voltages) are injected into the archive, since they are NOT used for calibration. They are stored at IWF and are used for monitoring the health of the instrument. Since this is in perfect order, NO HK data were used for calibration. MEASUREMENT data: CODMAC 2 level (RAW SENSOR DATA) are RAW data. Only known sensor effects are corrected; these RAW data contain a significant amount of variable spacecraft background field. 1) CODMAC 2 level (RAW SENSOR DATA) inflight data products with 1 Hz data resolution, i.e. Solar wind mode, are available for the whole mission duration (after Venus orbit insertion, 12 April 2006) and nearly without datagaps, since MAG is ON in principle at ALL times. To obtain continuous 1Hz datacoverage, all data intervals of higher data rate are downsampled on ground with the same methods as onboard (see 2.2.4) and merged into the 1 Hz data set, to enable a full coverage with equidistant samples in time. 2) CODMAC 2 level inflight data products with 32 Hz data resolution are available for short time intervals (2x10 mins to 2x2 hours) around pericenter after start of the nominal mission (14 May 2006) Data intervals of higher data rate are downsampled with the same .. methods as onboard (see 2.2.4) and merged into the 32 Hz data set. 3) CODMAC 2 level inflight data products with 128Hz data resolution are truncated!, Please s [truncated!, Please see actual data for full text]
