0.0625-s Chronicle Data, in Spacecraft Coordinates

Description

This data set, provided by the principal investigator, consists of scalar and vector magnetometer data on binary magnetic tape created on an IBM 360/91 computer. In this data set the vector magnetometer data are given in the spacecraft coordinate system. These data are at the highest possible time resolution, which is 8 scalar magnitude measurements and 16 vectors per second. Each logical record consists of an orbit data record, scalar magnetometer data records, and vector magnetometer component data records. Each record type contains data type, modified Julian day of first observation, milliseconds (ms) of day, time increment between observations (ms), and time offset. The orbit data records contain 128 values of inertial coordinates, invariant latitude, geomagnetic time (hours), and dip latitude. The scalar data records contain 512 values (in nT) of scalar observations. The vector records contain 1024 values (in nT) of vector component observations. For additional information see references given under NSSDC ID 79-094A-01A. This data set is entered under NSSDC ID numbers 79-094A-01B and 79-094A-02B.
