NSSDCA ID: SPHE-00861
Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)
Time span: 1973-10-30 to 2000-06-10
This data set was created at NSSDC by converting the PI-provided 15.36-sec binary data set (73-078A-01N) to ASCII and simultaneously rejecting many little-used data words. The parameters chosen for inclusion in this data set are: time, spacecraft position (GSE and GSM), field magnitude, field Cartesian components (GSE and GSM), and the variances and covariances of the GSE field component averages. Unlike its source -01N data set, this data set uses a common January 1 = day 1 convention throughout. An earlier version (-01M) of this data set was initially created (from earlier binary data set -01A) in the early 1990's and was replaced in 2002 by this version with slightly different formatting which: used 4-digital year fields; fixed a previous end-of-day record loss problem; used variances and covariances rather than their square roots; fixed a problem with position information in last pre-data-gap records.
Ths data set is accessible via https://spdf.gsfc.nasa.gov/pub/data/imp/imp8/mag/ in the 15s_ascii directory and with browse functionality via FTPBrowser at http://ftpbrowser.gsfc.nasa.gov/mag15s.html
