NEAR Magnetometer (MAG) Level 2 Data Archive (PDS)

NSSDCA ID: PSFP-00260

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1997-06-28 to 2001-02-12

Description

This data set contains level 2 processed vector magnetic field data acquired by the fluxgate magnetometer (MAG) on the NEAR spacecraft. The data are processed science data provided in physical units (nT) in two coordinate systems Near Sun Orbital (NSO) and Eros Body Fixed (EBF). Instrumental and spacecraft effects have been removed from the data during processing. The data are provided in ASCII tables located in the DATA directory. Plots of the data are also provided for browsing purposes in the BROWSE directory. Spacecraft position is also included in the data tables and plot files.

Raw data contained in the level 1 MAG dataset were processed by applying a series of corrections known from pre-flight calibrations and removing spacecraft fields evaluated in-flight. A summary of the calibration process is provided in the MAG_CALIBRATION document. The data are divided into volumes which contain cruise, Eros fly-by, Eros orbit, Eros surface, and Earth fly-by data. The volumes containing each file, the PDS ID, and the date range covered (in the form YYYYDDD) are given below:
