15 Sec Averaged Vector Magnetic Field Data

Description

This data set has been restored from 1600-bpi to 6250-bpi binary magnetic tapes in IBM representation. Each tape has only one file that contains 9090 physical records (except for the last tape). Each physical record contains 4 control bytes followed by 60 logical records. Each logical record contains, in 68 4-byte words, averaged magnetic field data and spacecraft information for one 15.36-s interval. The data consist of: (1) field magnitudes, (2) Cartesian components in solar ecliptic and solar magnetospheric coordinates, (3) field latitude and azimuth angles in payload, solar ecliptic, and solar magnetospheric coordinates, and (4) auto-variances and cross-variances in payload coordinates (almost the same as solar ecliptic coordinates). In addition, data quality flags, spacecraft ephemeris data, housekeeping data, and various other parameters are included.
