Fast Plasma Bow Shock Crossing Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1977-11-07 to 1978-01-01


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, bow shock crossing data are on a ASCII magnetic tape created on a CDC 7600 computer. The data are blocked with fifty 80-character card images per physical record. The first 80-character record of each block contains the date in year, month, and day. It is followed by 49 records containing time in seconds from midnight; universal time; particle density; alpha fraction; velocity; phi and theta (angles in deg); parallel and perpendicular temperatures; and velocity difference. These data were submitted as input for Coordinated Data Analysis Workshops and are therefore limited to discrete periods within the time interval covered.
