    • We consider the asymmetry to be small if at high magnetic field each of the dots is singly occupied in the ground state in contrast to the large asymmetry case for which only the deepest dot is occupied.

    • In a single dot the first spin-polarized ground-state appears between B=5 T and 15 T for V=25 meV and between B=6.5 T and 19.5 T for V=35 meV.
