DESCRIPTION |
This collection 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.
