This data set contains hour-averaged magnetic field vectors from the Ness/Mariani experiment on Helios 2. Each record contains time, magnetic field intensity and cartesian components in spacecraft-centered solar ecliptic coordinates, standard deviations, numbers of fine-scale points in the average, and an instrument mode indicator. It should be noted that the "average" mode, which was used a minority of the time and involved on-board averaging, may have incorrectly handled range changes caused by occasional significant changes in ambient field intensity. The data set had not been filtered for this effect upon delivery to NSSDC. The delivery to NSSDC involved one zip'd diskette containing Helios 1 and 2 data. The data are available on-line at: https://spdf.gsfc.nasa.gov/pub/data/helios/helios2/mag/hour_ness/
The data (unzipped) are also accessible on COHOWeb at: http://cohoweb.gsfc.nasa.gov/cw.html
and will also be available on the 1996 edition of NSSDC's heliospheric CD-ROM. As this description is created, we had not yet decided whether or how to include the "average" mode data in these value-added data products.
