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 These data are expected to be superseded by Version 3 data to be based on an improved calibration.
