Cassini MAG Full Resolution Magnetic Field Data

ResourceID
spase://NASA/NumericalData/Cassini/MAG/Full_Res/V1

Description

This PDS-accessible data set contains Cassini magnetic
field data at the highest resolution available as of May, 2012. The MAG
instrument consists of the fluxgate magnetometer (FGM) and helium
magnetometer that is sometimes operated in vector mode (VHM) and sometimes
in scalar mode (SHM). The data for any time may be from any one of these
(a flag indicates which), althought seems to be mostly from FGM. Time
resolution is variable from time to time, ranging at least from 4 vectors/min
to 32 vectors/sec. Nominally, FGM transmits 32 vectors/sec, and VHM and
SHM 2 and 1 vectors/sec, at normal downlink data rate. Magnetic field
Cartesian components are given mostly in RTN coordinates for the Cassini
cruise phase (1999-08-16 to 2004-05-14) and in Kronographic coordinates
at Saturn (>= 2004-05-14). Spacecraft trajectory data are not included
in the data records. These data are expected to be superseded by
Version 3 data to be based on an improved calibration.
