  One-electron tunneling through a quantum dot with a strong magnetic field in
the direction of the current is studied. The linear magneto-conductance is
computed for a model parabolic dot with seven electrons in the intermediate
states and for different values of the magnetic field. It is shown that the dot
density of states at low excitation energies can be extracted from a precise
measurement of the conductance at the upper edge of the Coulomb blockade
diamond. We parametrized the density of states with a single ``temperature''
parameter (in the so called ``constant temperature approximation''), and found
that this parameter depends very weakly on the magnetic field.
