8-Second Averaged Spectral Density 8 Channel 6.8-1490 HZ Data


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1976-01-15 to 1976-11-21


This data set in written by a PDP computer in binary code. Each tape has a single file. The records are of different lengths. The first record is a header. It is followed by pairs of records: the first provides the day number and its fraction; the second provides several 8-s averaged values of the amplitude and peak values encountered during the 8-s interval, of the magnetic field components in 8 frequency bands. These bands are centered at 6.8, 14.7, 31.6, 68, 147, 316, 681, and 1470 Hz, and have widths +/- 50% of the frequencies. The Z-component amplitude is taken in the direction of the spin axis, and the X-component from one of the equatorial plane antennas. Among other entries are the ecliptic longitude, latitude, and heliographic latitude of the spacecraft, and the Helios-sun-earth angle. Quality flags are also provided.
