--------------------------------------------------------- NSSDC Master Catalog Display Data Set --------------------------------------------------------- Hourly Averaged Magnetic Field Data on Floppy Disk NSSDC ID: 76-003A-02C Mission Name: Helios-B Experiment Name: Fluxgate Magnetometer for Average Fields Availability: Data at NSSDC Ready for Distribution Time Span: 1974-12-14 to 1977-12-31 (as determined by NSSDC) Description This data set contains hour-averaged magnetic field vectors from the Ness/Mariani experiment on Helios 1 [or 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 (unzipped) will be accessible on NSSDC's COHOWeb at URL: http://nssdc.gsfc.nasa.gov/cohoweb/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. ------------------- Discipline(s) Space Physics/Heliospheric Studies Media Information 1 Floppy Disk --------------------------------------------------------- NSSDC Master Catalog Display Data Set Personnel --------------------------------------------------------- Hourly Averaged Magnetic Field Data on Floppy Disk NSSDC ID: 76-003A-02C General Contact Prof. Franco Mariani Istituto di Fisica G.
