For a circular two-dimensional parabolic dot in perpendicular <magnetic field>, orbital levels are $\hbar\Omega(2n+|\ell|+1)\pm\ell\hbar\omega_c/2$, with $\Omega^2=\omega_0^2+\omega_c^2/4$. The sign depends on the angular-momentum and signed-charge convention. At zero field the shell degeneracy is $q+1$ before <spin>; Zeeman and interaction terms require separate treatment.
