MESSENGER MAG Low-Rate Housekeeping Information Data Collection
Short Name:
MESS-RAW-LHK
Date:

Publisher:
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.
MESSENGER Magnetic Crustal Field Map Data Collection
Short Name:
MESS-MAG-Crustal
Date:

Publisher:
Planetary Data System
Description:
This collection consists of ASCII files containing derived magnetic
field maps and equivalent source dipole arrays for the crustal
magnetic field of Mercury. Zero values (mainly found along the map
edges) indicate no useful data.
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
Short Name:
MESS-RAW-SHD
Date:
03 Feb 2023 20:18:09
Publisher:
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).
