Abstract:
In our companion papers (Hollick+ 2018ApJ...863...75H 2018ApJ...863...75H and
2018ApJ...863...76H 2018ApJ...863...76H) we analyze 637 intervals of magnetic wave
activity observed by the Voyager 1 and 2 spacecraft from its launch in
1977 through the end of 1990. We argue that these waves originate from
cyclotron resonance with newborn interstellar pickup He+ and H+. As
the list of wave events is long and potentially useful to other
researchers, we take this opportunity to list the times of those wave
events here, along with their heliocentric location, ellipticity
(often referred to as polarization), and whether thermal ion data is
available from the PLS instrument. A brief overview of the analysis
contained within the companion papers is also provided.
