5-min Average B-Field Vector Data

Description

This data set contains 5-min averages of the magnetic field vector. Each record provides time, spacecraft location (km) in GSM and GSE coordinates, and average magnetic field vector components (nT) in each coordinate system. Also given are the 5-min average of the field magnitude, derived from the averaged components, the average magnitude directly computed from high resolution magnitude values, and the average direction angles theta and phi in the GSE system. The data are written in binary on magnetic tape, in fixed length blocks of 27,000 bytes, with logical records of 180 bytes.
