108/ 108-Second Average Modulated Signal Strength   https://nssdc.gsfc.nasa.gov/nmc/dataset/display.action?id=ASRA-00002
Time span: 1978-08-13 to 1987-03-28
NSSDCA ID: ASRA-00002  OLd: 78-079A-10G
This collection contains modulated radio data, at 108-s 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 and 3 kHz. The complete sequence was covered in 108 seconds. Parameters included are time, various S and Z sample averages for 12 frequency channels, mode, spacecraft GSE coordinates, and Z dipole configuration.

Data sets ASRA-00008 and ASRA-00004 are similar, but at 1.5-s resolution, and ASRA-00008 has been analyzed (despun) to yield source longitude and elevation angles.


1_5S/  1.5-Second Modulated Signal Strength https://nssdc.gsfc.nasa.gov/nmc/dataset/display.action?id=ASRA-00004
NSSDCA ID: ASRA-00004 Old: 78-079A-10F
Time span: 1978-08-13 to 1987-03-28
This collection contains modulated radio data at 1.5-s 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 collections ASRA-00002 and ASRA-00008 are similar, but ASRA-00008 has been analyzed (despun) to yield source longitude and elevation angles, and ASRA-00002 has a resolution of 108 s, which is the length of a complete instrument sequence of measurements.


demod:  1.5-Second Demodulated (despun) Signal Strength, with Source Locations https://nssdc.gsfc.nasa.gov/nmc/dataset/display.action?id=ASRA-00008
NSSDCA ID: ASRA-00008  old: 78-079A-10E
Time span: 1978-08-13 to 1987-03-28
This collection contains demodulated (despun) radio data at 1.5-s 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.

Collections ASRA-00002 and ASRA-00004 are similar but have not been despun, and ASRA-00002 has a resolution of 108 seconds, which is the length of a complete instrument sequence of measurements.
