资源简介：
The Magnetic Field Experiment (MAG) consists of twin vector fluxgate
magnetometers controlled by a common CPU. The sensors are mounted on
booms extending 4.19 meters from the center of the spacecraft at
opposite sides along the +/-Y axes of the spacecraft. The instrument
returns 6 magnetic field vector measurements each second, divided
between the two sensors, with onboard snapshot and FFT buffers to
enhance the high-frequency resolution.
MAG level 2 data is organized into 27 day time periods (Bartels
Rotations - roughly one solar rotation period). For each Bartels
Rotation, the level 2 data contains time averages of the magnetic
field data over the following time periods:
- 16 seconds
- 4 minutes
- hourly
- daily
- 27 days (1 Bartels rotation)
