Dynamics Explorer-2 (DE 2) Magnetometer Instrument (MAGB) Data

This directory gathers data for the MAG-B instrument that flew on the DE 2 spacecraft 
which was launched on 3 August 1981 into an elliptical orbit with an altitude range 
of 300 km to 1000 km and re-entered the atmosphere on 19 February 1983. 

/gms_62ms_vmsbin   (NSSDC ID: 81-070B-01G)

These high-resolution (16 samples per second) MAGnetometer (MAG-B) data are provided 
in GMS coordinates in VAX binary fixed-length format as daily files including orbit 
information. The data are for the time period from Aug 10, 1981 to Feb 16, 1983. 

The following documentation files are included in this directory:

magb_insturment_data.txt: A description of the MAG-B instrument and data
data_format_description.txt: A description of the MAG-B GMS data format and software 
read_data.pro: An IDL program to read data into arrays 
read_and_average_data.pro:  An IDL program to read and average the data 
read_requiring_VAX_UNIX_conversion.pro: An IDL program to read data, requires VAX to 
	UNIX conversion subroutine
VAX_UNIX_conversion.pro:  IDL subroutine for VAX to UNIX conversion 

Merged VEFI-MAGB data set:

MAGB data are also available online in the form of merged VEFI and MAG-B data sets 
(1/2-second and 1/16-second resolution) in directory magnetic_electric_fields_vefi_mag
and the 1/2-second data also for plotting at
