Merged Hourly Averaged Field-Standard Deep Space IMF/Solar Wind Data


Availability: Archived at NSSDC, accessible from elsewhere

Time span: 1973-11-03 to 1974-09-18


This data set, on magnetic tape, contains 1-h averages of the interplanetary magnetic field. The data were derived from data set 73-085A-04C. The data were corrected to solar equatorial X, Y, and Z components; and the Carrington longitude, Carrington rotation number, and earth-sun-spacecraft angle were added by NSSDC, to put the data into the standard format of the deepspace mission solar wind data series produced by NSSDC. The eight words of the standard format reserved for plasma data are set to zero in this data set. The data set consists of one file of ASCII-character documentation and one file of IBM 360 binary data. The data points are referred to spacecraft event time. The parameters included are time, spacecraft heliocentric distance, Carrington rotation number, Carrington longitude, heliographic latitude, earth-sun-spacecraft angle, and magnetic field vector in the solar equatorial system, both in rectangular coordinates and in spherical coordinates. The rms deviations of the rectangular components and magnitude are also given.
