Voyager 1 Fluxgate Magnetometer Hourly Average Cruise Data Archive

Description

These data contain hour averages of the interplanetary magnetic field (IMF) measurements obtained by the dual magnetometer triaxial fluxgate systems on Voyagers 1. The instruments were designed to measure the IMF between Earth and Saturn (10 AU) during the primary Voyager mission. The design and performance yielded absolute accuracies to better than < 0.1 nT. In general, each component of the IMF hourly average has an uncertainty of up to (+/- 0.05 nT) in the region beyond 10 AU. More accurate measurements could only be obtained by special processing of the data, but it was not feasible to do this for the entire data set included here. The instrument was described by Behannon et al., Space Science Reviews, 21, 235, 1977.
