11. The convergence for the restriction of the configuration space is checked for N = 4, comparing the ground state energies with ten and 15 orbitals. The difference is within 0.1% (0.8%) in the small (intermediate) interaction case.

13. The restriction of the configuration space may result in numerical inaccuracy. Generally, however, the correlation effect is larger for the low-spin state and thus this estimation for the high-spin region is expected to give a wider limit.

15. This calculation with a restricted configuration space becomes a better approximation when the magnetic field is sufficiently high, because the one-electron levels of n = 0 and m > 4 hardly appear as long as the total angular momentum M ≤ 4 (5) for N = 3 (4).
