54-Sec Electron Density & Temperature During Tail Traversal of Comet G-Z


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

Time span: 1985-09-11 to 1985-09-11


These experimenter-supplied data obtained from the radio astronomy experiment during the tail traversal of comet Giacobini-Zinner cover the interval 10:00 UT to 12:00 UT on September 11, 1985. This data set consists of plasma particle measurements deduced from radio wave measurements. Values of electron density and temperature are determined from spectroscopy of the thermal noise spectrum. The data parameters are time, electron density, and electron temperature. The data were provided in ASCII format. To determine the plasma parameters, the electron distribution function is assumed to be bi-Maxwellian. The total electron density is derived from the cut-off frequency of the thermal noise spectrum. The time resolution is 54 seconds. This data set does not contain any spacecraft position information. Trajectory data for the ICE spacecraft relative to the comet are archived separately as data set 78-079A-00E. Data from the following other experiments on ICE for part or all of the same period are also archived: Solar Wind Plasma (78-079A-01R), Vector Helium Magnetometer (78-079A-02N), Low-Energy Cosmic Rays (78-079A-03E), Plasma Wave (78-079A-07D), and Energetic Proton (78-079A-08F).
