LANL PLASMA DATA FROM IMP-6 (2-min. resolution)

This home page provides access to the IMP-6 2-minute resolution data set from the Electrostatic Analyzer instument provided over the years by Los Alamos National Laboratory (LANL). Magnetosheath data were excluded from the 2-min data by LANL.
The original ASCII data set is placed at SPDF's anonymous FTP site in directory
At this directory a user can find a description of the data .

Time span 1971-03-18 - 1974-08-03
