VG2 JUP PLS DERIVED ION IN/OUTBND MAGSHTH L-MODE 96SEC V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: August 03, 2025 | Last Modified: 2025-07-17
This data set contains plasma parameters from the Voyager 2 inbound magnetosheath and outbound data from the magnetotail through the solar wind. Inbound Voyager 2 passed near noon local time, so it sampled regions of the magnetosheath where flow is generally subsonic. Distribution functions observed were well represented by two convected isotropic proton Maxwellians, so this type of distribution was used to derive the proton velocity, density and temperature. Physically the two populations represent the thermal plasma accelerated at the shock (the colder component) and ions reflected once at the shock before entering the magnetosheath (the hotter component). The PLS experiment could not resolve alpha particles in this region so no alpha parameters are provided; the neglect of alpha made cause an overestimate of the hot proton component of the plasma. One sigma errors are provided for the fit parameters.
