  We present electron transport calculations of shocked argon based on an
average-atom modeling of the plasma, and compare them with measurements,
involving both incident and reflected shock waves. Since the corresponding
experiments are subject to a 5 T magnetic field, the impact of the latter on
the Rankine-Hugoniot equations is taken into account, starting from the
magneto-resistive hydrodynamics, and the resistivity tensor is deduced from the
Boltzmann equation. The resistivity tensor yields the electrical and Hall
resistivities. Our average-atom code Paradisio provides the quantities required
for the calculation of electrical resistivity within the Ziman-Evans formalism,
as well as for the Hall resistivity. We obtain a good agreement between
calculated conductivities and experimental values, both for the incident and
reflected shocks. Our values of the Hall constant are compared to experimental
values derived from Hall voltage measurements, as well as to theoretical ones
based on the quantum statistical linear-relaxation-time approach.
