These two data sets are of similar format. Both contain 1-minute averages of the
magnetic field, in ASCII.

1. 1min_1978_1983/
   NSSDC ID: SPHE-00843
   Old ID: 78-079A-02T

This data set covers the earth-centered phase (1978-1983) of the ISEE 3 mission, 
and its spacecraft position parameters give the spacecraft position only in 
geocentric GSE coordinates. 

2. 1min_hgi_1984_1990/
   NSSDC ID: SPHE-00844
   Old ID: 78-079A-02U

This data set covers the heliocentric phase of the mission (1984-1990), and its 
spacecraft position parameters give the spacecraft position in GSE coordinates and
also in heliocentric coordinates HGI.
