1.5-Second Modulated Signal Strength


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

Time span: 1978-08-13 to 1987-03-28


This data set contains modulated radio data at 1.5-second resolution. The data pertain to solar type III radio bursts. The S dipole antenna lies in the spin plane; the Z dipole lies along the spacecraft spin axis. Measurements were made in 12 frequency channels, between 30 and 1980 kHz, in each of two bandwidths, 10 kHz (B), and 3 kHz (N). Signal strengths are identified by the combination of a dipole letter and a bandwidth letter. Parameters included are time, frequency channel number, calibrated S and Z samples as log of antenna temperature, SB or SN average amplitude, SN rms amplitude, spin period, s/c GSE coordinates, sun angle, and an array of calibration and housekeeping values. Data sets 78-079A-10E and 78-079A-10G are similar, but -10E has been analyzed (despun) to yield source longitude and elevation angles, and -10G has a resolution of 108 seconds, which is the length of a complete instrument sequence of measurements.
