1.5-Second Demodulated (despun) Signal Strength, with Source Locations


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

Time span: 1978-08-13 to 1987-03-28


This data set contains demodulated (despun) radio data at 1.5-second resolution. Source locations (in the interplanetary medium) are included for the electrons that generate the 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, despun SB and/or SN amplitude, modulation index, average Z amplitude, phase, phase sun angle, source longitude, source elevation angle, source radius, background values, standard deviations, uncertainties, number of samples, mode, spin period, and spacecraft GSE coordinates. Data set 78-079A-10F and 78-079A-10G are similar but have not been despun, and -10G has a resolution of 108 seconds, which is the length of a complete instrument sequence of measurements.
