VEX-V-Y-MAG-4

This data set comprises resampled calibrated data from the Venus Express Mag (MAG) instrument, i.e. resampled space magnetic field in nanoTesla and in VSO coordinates. The time resolution is 4sec, resampled from 1Hz calibrated data. Full datacoverage 24 hr per day is available with only few datagaps. The basic data were collected during the Venus Express mission from Launch (9th November 2005) to the end of the nominal mission(03 Oct 2007). 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 4 level are RESAMPLED CALIBRATED data in nano Tesla and VSO coordinates, with a timeresolution of 4 secs. These data are downsampled from the 1Hz calibrated CODMAC 3 data. DIRECTORY NAMING CONVENTIONS: In the DATAdirectory, data are archived according to different phases from the flight before the Venus Orbit Insertion. After Venus orbit injection, data directories are archived according to DATA PHASE NAME, which is according to DATE and not according to orbit numbers. Therefore, all DATAdirectorynames contain a DATA PHASE NAME, as defined in Table below, and an indication of the data or timeresolution of the data.

本数据集囊括了来自金星快车号磁强计（MAG）仪器的重采样校准数据，即以纳特斯拉和VSO坐标形式的重采样空间磁场。其时间分辨率为4秒，由1Hz校准数据重采样而来。数据覆盖范围全天24小时，仅存在少量数据空缺。基本数据收集自金星快车号任务从发射（2005年11月9日）至常规任务结束（2007年10月3日）。基本数据包括未经校准的原始测量数据、校准数据、重采样数据以及几何信息。此外，还包括相关文档。
数据内容：
维护数据：由于未用于校准，未在档案中注入任何维护数据（如温度、电压）。这些数据存储在IWF，用于监控仪器状态。鉴于仪器状态良好，未使用任何维护数据进行校准。
测量数据：CODMAC 4级数据为重采样校准数据，以纳特斯拉和VSO坐标表示，时间分辨率为4秒。这些数据由1Hz校准的CODMAC 3级数据进行下采样。
目录命名规范：在数据目录中，数据根据金星轨道插入前的飞行阶段进行归档。金星轨道注入后，数据目录根据数据阶段名称进行归档，该名称根据日期而非轨道编号。因此，所有数据目录名称均包含数据阶段名称，如下表所示，以及数据的或数据的时间分辨率。数据阶段名称 | 数据阶段名称ID | 数据目录名称 | XXXXXXXXX 在地球上的调试阶段 | COMMEARTH | 航行阶段 年月 | CRU200601 | CRU200602 | CRU200603 在金星捕获轨道 | CAPTORBIT
