5 Minute Averaged B 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. There are 52 files corresponding to 52 intervals of observations. The data are written in fixed length blocks of 8,284 bytes. All data in a block are 4-bytes, real and binary.
