EDI Prime Parameter Data
After submitting a month and year through the above interface, your web browser will be directed to a page that contains zipped CDF files. You will have the option of downloading data for the entire month or individual days. In either case, each file contains CDF files for SC1, SC2, and SC3. CDF is the standard file format for the Cluster mission. It may be
converted to ASCII using the QTRAN software available from Queen Mary,
University of London, where one can also obtain the powerful QSAS plotting and analysis
package. The Cluster Prime Parameter database begins with February 1, 2001. At this time, EDI PP data can be downloaded through December, 2005.
NOTES:
1. EDI processed data are obtained by combining multiple return-beams
within each analysis interval, using either the triangulation or
time-of-flight technique, to determine the drift velocity perpendicular to
B. The data files contain both the drift velocity, and associated (-VxB)
electric field, in inertial GSE coordinates (after subtracting the
spacecraft velocity). The ground analysis provides a statistical assessment
of the "quality" of each result, which we classify as "good", "caution", or
"bad". The PP data available here were processed using a single spin (4
second) analysis interval, and have been filtered to retain only "good"
results. The assignment of "good" is based on an automated algorithm, and
should not be taken as a guarantee of each point. In some instances
improved results can be obtained with manual adjustments to the filtering,
analysis intervals, or processing parameters. For assistance or with
questions about individual events, please contact the EDI team:
