  Given their uniqueness, the Ulysses data can still provide us with valuable
new clues about the properties of plasma populations in the solar wind, and,
especially, about their variations with heliographic coordinates. We revisit
the electron data reported by by the SWOOPS instrument on-board of the Ulysses
spacecraft between 1990 to early 2008. These observations reveal velocity
distributions out of thermal equilibrium, with anisotropies (e.g., parallel
drifts or/and different temperatures, parallel and perpendicular to the
background magnetic field), and quasi-thermal and suprathermal populations with
different properties. We apply a 2D nonlinear least square fitting procedure,
using the Levenberg-Marquardt algorithm, to simultaneously fit the velocity
electron data (up to a few keV) with a triple model combining three distinct
populations: the more central quasi-thermal core and suprathermal halo, and a
second suprathermal population consisting mainly of the electron strahl (or
beaming population with a major field-aligned drift). The recently introduced
$\kappa$-cookbook is used to describe each component with the following
anisotropic distribution functions (recipes): Maxwellian, regularized kappa-,
and generalized kappa-distributions. The temperature anisotropy quantified by
the best fits is considered as a case study of the main parameters
characterizing electron populations. By comparison to the core, both
suprathermal populations exhibit higher temperature anisotropies, which
slightly increase with the energy of electrons.
