Helios/IMP-8/ISEE-3 Archive Access
To learn about two-spacecraft data set challenges it is useful to revisit the Helios 1/2 mission data. Toward that end, we here provide access to Carrington Rotation browse plots and browse data for solar wind parameters, Solar Energetic Particles (SEPs) and orbit information. Use of these data in presentations or publications should acknowledge the providers Rainer Schwenn at the Max Planck Institut, Lindau (solar wind and orbit data) and Don Reames at GSFC (SEP data - GSFC), Horst Kunow and Reinhold Mueller-Melin (SEP data - Kiel), Principal Investigator Helmut Rosenbauer as well as the other original Helios investigators. The archived IMP-8 data is courtesy of its investigators and the NSSDC
Helios data summary:
| Instrument | Energies | Resolution | Channels |
|---|---|---|---|
| SEP p+ (Kiel) | 4-51 MeV | 1-15 min. | 6 |
| SEP p+ (GSFC) | 3-57 MeV | 30 min. | 6 |
| SEP α (Kiel) | 2-8 MeV | 1-15 min. | 6 |
| SEP e- (Kiel) | 0.3-2 MeV | 1-15 min. | 4 |
| Plasma (MPAE) | N/A | 81 sec. | N/A |
| MAG (Rome/GSFC) | N/A | 81 sec. | N/A |
IMP-8 & ISEE-3 data summary:
