Fast Plasma Experiment Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1977-12-01 to 1977-12-12


This data set is proprietary and not for distribution. It is submitted by experimenters to NSSDC for the purpose of the Coordinated Data Analysis Workshops (CDAW). The data sets submitted for CDAW are usually small, and the time coverage is usually scanty within the time span indicated. However, this data set (or part of it) may be provided to the general science community through an online data set in CDF format. For more detailed description, as well as access information, please contact the NSSDC Request Coordination Office at

These experimenter-supplied, fast plasma data are on binary magnetic tape created on a CDC 6600 computer. The records are blocked with 20 140-byte logical records per physical record. Each logical record contains satellite identification number (1 or 2 for ISEE 1 or 2); description of mode of operation; proton and electron low/high energy sweep; year, day of year, and milliseconds of day at start of sweep; orbit number; spin period (in seconds); spacecraft position in solar ecliptic coordinates; and the following variables for both proton and electron data: density, bulk speed, flow azimuth (ecliptic plane), mean temperature (deg K), and density of energetic part of distribution (electrons above approximately 2 keV or protons above approximately 7 keV).
