MESSENGER MAG Low-Rate Header Information Data Collection
Short Name:

Publisher:
Planetary Data System
Description:
MAG instrument state (health and mode) as reported by the LRHK
packet. This changes only on packet boundaries so it is kept in a
separate EDR, minimizing repetition of information. Each row in the
LHRK Header EDR corresponds to information extracted from one LHRK
packet.
MESSENGER MAG Low-Rate Housekeeping Information Data Collection

Planetary Data System
Description:
This collection contains tables of instrument state as reported by
the MAG Low-Rate Housekeeping (LRHK) packet. It includes the 3-axis
field values (received from the filter and subsampling logic) and the
corresponding AC values.
This collection contains snapshots of MAG vector samples, or burst
sampling, over a time span of 8 minutes, at a rate of 20 samples per
second for a total of 9600 vector samples. The burst data give
information about waves and turbulent phenomena expected to occur at
the magnetospheric boundaries and elsewhere in association with pickup
processes of volatile species as they are photo-ionized. Typically one
burst period will be recorded every day of orbit operations.
MESSENGER MAG Raw Science Header Information Data Collection

Planetary Data System
Description:
Captures the instrument state (health and mode) as reported by the
science packet. This information only changes on packet boundaries so
it is kept in a separate EDR, minimizing repetition of information.
Each row in the Science Header EDR corresponds to the information
extracted from one science packet.
MAG instrument raw status information, temperatures, voltage, command
status counts as well as low-resolution (14-bit) 3-axis magnetic field
samples as recorded by A/D converters integral to the Low Voltage
Power Supply (LVPS).
MESSENGER MAG Time-Averaged Calibrated RTN Coordinates Science Data
Collection
Short Name:
mess_mag_calibra

Planetary Data System
Description:
Time-averaged spacecraft position and calibrated 3-axis magnetic
field samples in Radial-Tangential-Normal (RTN) coordinates. The
spacecraft postion is given by the radial distance from Sun center,
northward latitude above the instantaneous ecliptic plane, and azimuth
angle of the spacecraft in the instantaneous ecliptic plane with
respect to the Earth-Sun line, positive in direction of the Earth's
orbital motion. The data are tagged with latency corrected UTC and MET
time stamps at the center of each interval. The RTN RDR is derived
from the Science CDR for this coordinate system with time averages
computed within 1, 5, 10, and 60 s intervals.

Description:
Time-averaged calibrated 3-axis magnetic field samples in sensor and
spacecraft coordinates. The data are tagged with latency corrected UTC
and MET time stamps at the center of each interval. The SC RDR is
derived from the Science CDR for this coordinate system with time
averages computed within 1 s intervals.
