These 1-hr. FIT plasma data are a subset of data at the MIT website:
ftp://space.mit.edu/pub/plasma/imp/hr_avg/. They were reorganized
and reformatted at NSSDC, updated in Nov. 2003 and placed at the NSSDC site:
https://spdf.gsfc.nasa.gov/pub/data/imp/imp8/plasma_mit/solarwind_hr/
These data are nominally all from the solar wind phases of the IMP orbit.
The day number convention used is January 1 = day 1.
The flow azimuth (E/W) angle is positive for flow from west of the sun.
The flow elevation (N/S) angle is positive for flow from south of the
sun. The aberration in velocity due to Earth's motion around the Sun
has been removed. Flow cartesian components may be directly computed
from these angles and the flow speed.
Note: this directory. include aareadme_mit.txt from MIT site to get more
